I'm going to cover with you how to check for permanent codes and how permanent diagnostic troubles codes (PDTC) differ from (DTC) pending or stored. I will also show how you can get help with your 1996 -2009 Vehicle when inspection monitors are not setting. Permanent codes cannot be cleared by disconnecting the vehicle's battery.

Cool information about permanent Diagnostic Trouble Codes PDTC
Permanent Diagnostic Trouble Codes (PDTCs) are very similar to regular Diagnostic Trouble Codes (DTCs). However, unlike regular DTCs, they cannot be reset by disconnecting the vehicle's battery or cleared using an On-Board Diagnostic (OBD) scan tool.
A Permanent DTC can only then be cleared by the module strategy and cannot be erased by clearing DTCs with a scan tool, a Keep-Alive Memory (KAM) reset, or battery disconnect.
Mode $0A lists emission-related "permanent" diagnostic trouble codes stored. As per CARB, any diagnostic trouble codes that is commanding MIL on and stored into non-volatile memory shall be logged as a permanent fault code.
These are the new, emission-related DTCs that can’t be cleared from the ECM or TCM until the computer knows for sure that the problem was fixed. This usually involves performing a Universal Trip Drive Pattern exactly as described, but there are other ways, such as performing a dedicated monitor cycle. Permanent DTCs first appeared on certain 2009 vehicles, and are being legislated on 2010 vehicles. As with any new technology, the “glitches” may need to be worked out in the field, so reading the repair manual and TSBs are important steps before beginning diagnosis.

Clear permanents codes by FIXING THE PROBLEM. Jesus how helpful, we really needed a 10min video for nothing.
Well said!!
@@RANDOMFIX Dumbest video ever
I cleared my permanent code (Purge Valve) and drove it over 300 miles. Still will not clear...
Great video. I have just learned about “permanent” codes. The vehicles I normally work on are older than 2010.
Glad to help and thank you for the feedback, yeah that’s pdtc are a pain in the neck!!!
so the permanent codes are there to prevent cheating emission tests which is good for the environment but then you have to drive aimlessly burning gas and releasing carbon for 200 km just to clear the damn code every time it shows up
Exactly.
If you drive a ram 1500 idling the engine for 5-10 minutes at a time WILL cause hemi tick due to lack of lubrication on the lifters, which then wear and beat the snot of the cam lobes and eventually kill the engine. What's also annoying is everytime the code reappears the engine turns off mds which is what deactivates cylinders for an eco friendly drive lol. I swear they want you to destroy your vehicle so you'll buy another.
15/200. . Idiots...
Came across one for the first time. I suspected the things you presented in this video, but appreciate the confirmation and other information I didn't yet have. Great video. Thank you for sharing.
Glad to help and good luck with setting your drive monitors.
@@RANDOMFIX Thank you. Waiting on the part. Should (fingers crossed) be a fairly simple fix.
This Code system is so unconstitutional. It's just another hurdle created in order to keep people from working on their own equiptment. I just recently dealt with this issue, its a bitch to drive 200 miles just to see if the system will allow you pass. This also screws with mechanics time table to complete a repair. We need a way to hack this junk, and anyone who is okay with this legislation is trash.
That was pretty slick how you showed a photo of a OBD reader, and the title "How to clear Permant Diagnostic Trouble Codes..." It gives the impression you're going to show us all a neat hack to remove pesky PDTC's when in fact you merely tell us we really can't clear the codes, you have to fix problem, then let the car delete the codes. Very smart way to get views!
But that’s the truth. How else would I be able to tell you that?
@@RANDOMFIX it isn't helpful. You didn't clear the code - you fixed the problem. For me, I have a code that was thrown that will not me START the vehicle. There is actually no problem, due to DEF levels, but the computer can't clear it because I can't start it. Just wasted 10 mins of my life.
What are you driving where the def is not letting the vehicle start? It gives you a count down from 10 to 0 on the remaining starts. Did you exceed the count down?
@@RANDOMFIX Title the video "You can't clear permanent codes". This is clickbait.
So from my assessment of this video it was nothing but click bait !!
Thank you SO much, this video is VERY helpful!
Larry, thank you for the great feedback. I need to make an update to this. Video as the rules have changed a little. Now if after 15 cycles your vehicle is not ready the smog technician can manually test. This is update for California at least but I am sure it affects others states as well.
Thank you my man. I was having a different permanent code 1299 after some bad coolant sensors put my truck into limp mode. Half my cylinders are running because the limp mode. So I’ll have to drive it around with half the performance until it clears. 🤦♂️
Thank you and taking time to great feedback and good luck clearing your p1299 an let me know if need any additional help.
Smog check is pointless anyways .. money hungry government
Thanks for the information …I made a tuneup on my Prius v and got hybrid battery replaced because I had p0a80 code and green bean battery still under warranty..any way beside p0a80 I have p0102/p2195/p01171 .After hybrid battery replacement and drive for almost 20 miles,the car was running well until today I got Engine lights on and the car now like before looks goes up and down accelerating and desacceleranting by it self …I have obd inova obd scan tool and even erasing the codes it came back again and again…Unfortunately I just bought the obd scan tool after replaced …MAF sensor ,head valve cover and gaskets related to it ..
Thanks for sharing how many miles are on your Prius v?
very informative! I had a bad ambient temp sensor on my MINI R56 and after the repair I cleared the CEL but the permanent code wouldn’t clear. you did great in explaining it so thank you.
Thank you so much for the feedback. These permanent codes are a real nightmare and will cause much confusion for many vehicle owners.
Did you get that code to clear yet? I'm still having issues with mine.
@@chickentendies4485 I just got the check engine light cleared Friday but the permanent code is still showing on the ODB2. I’m hoping after driving around in the next week or so it should clear
@@steezymiyagi yeah my obd2 is showing O2 sensor cycle not complete. And my code is still permanent since I did the repair on Thursday. Apparently we just have to keep driving it. Despite the fact that I've been driving in and out of town and I live on Galveston Island so I have to drive to the mainland, it still has not reduced to a pending or stored dtc.
@@chickentendies4485 my buddy is an auto technician and he told me it doesn’t matter if you drive the car for 10 minutes or an hour, it’s about having the car cool down and starting it up again 10-15 times. I think in a week or 2 you should be cleared up.
Thanks, nice to know it will self clear over time.
That's what I understood as well
Yes, but there are thing you can do to make the process faster.
Yes, but there are thing you can do to make the process faster.
What if my I/M ready doesn’t show a pDTC but a permanent code pops up when I do the OBD scan? If it was still an ongoing issue wouldn’t the code pop up again on I/M ready?
when you scan the vehicle is there any codes?
Should i clear the code everytime in pops up? Had all the problems fixed and the permanent code p0440 is still there but the check engine pops back up with the same code but also as a stored code every 25-30 miles. I can clear pending and stored but not permanent. I heard that i have to drive around but would the light just clear itself or would i have to clear first and then drive?
If your check engine light is turning back on with the same code after you have cleared it that means the issue still persists.
So don’t delete codes ? Just start and run 15 times to self clear ? When I use my obd2 scanner to clear it the codes remain permanent after I turn of and turn on again should I just drive around with the check engine light 15 cycles until it clears on it own? This what I understand correct ?
Yes, don't just drive, let the vehicle warm and idle for about 10 minutes and then for a 10 minute or longer drive around town.
I fixed my o2 sensor and my converter drove from ohio to Tennessee and check engine light still on with same perm. Code ... what should I do
Hopefully you used the oem o2 sensor. Did you clear the code after replacing the o2 sensor? Hey did you replace the o2 sensor? What dtc code did you have?
Just change my evap purge 2010 Lexus code p0441 Permanent drove to work yesterday check engine light came on again same code 😀 👍 you say it fixes itself over 15 drive cycles I'll try
keep me in the loop.
My 2016 f150 went into limp code. I replaced the part but it stayed in limp mode and now wont start. Any suggestions?
You need to scan it with a scan tool and see what’s pulling up. Have you tried disconnecting the battery for a few hours? Does it cranks? What part did you replace?
I have 2012 Nissan with a code for cat below threshold a mechanic recommended I changed the down stream 02 sensor which I did but the code is permanent about how many drive cycles do I need for that vehicle thanks
That’s what I covered in the video. You have to do many cold start warm up cycles and drive around town for 10-15 minutes. Is the new o2 sensor oem?
@@RANDOMFIX AutoZone oem
Turned out to be a bad Front Cat
Going through this right now with a 2018 Honda . Check engine light came on with 3 codes.. took it in for repair and it had a purge valve replaced. Check engine light went off after work was done. All codes gone except one permanent code ( small vacume leak ) the evap monitor will not complete so the car is staying in not ready mode for emissions check. My sticker expired last month and the dealer told me to just keep driving it around and the code should clear and the monitor should go to ready. Neither has happened in 2 weeks!! I have driven it everywhere and tried all the different drive cycles. Is it possible the dealer didn’t fix something right so the code is not going away allowing the evap monitor to complete? Gas is to dang expensive to be driving all the time just trying to get this code to clear or the monitor ready.
I hear you on the high gas prices. Fyi the evap is exempt even in California but the permanent code needs to clear by it's self.
This will help so you do meet to keep checking with a scan tool.
th-cam.com/video/cxpE_I1cKh8/w-d-xo.html
I would do a long warm up ( 10 minutes or even longer) and then drive a for 15 minutes around town and the freeway.
Keep me in the loop.
Hello, we’re you able to fix this issue? I’m going through something similar
lmao been 3 months for my 2015 wrx and the fuel system and egr still wont ready. Evap only went ready last week. 3 MONTHS
Any update? Going through the same situation small leak permanent code won't clear or flash
Evap code is except so take it to get smogged
Hey sir I just wanted to ask a question I have bmw 328 i 2011 I was getting the misfire codes as permanent i just called the sparks and coils and I delete the code and when I start it no check engine light … i drive for hours no check engine light when I turn of and turn on car again check engine light is there and the permanent codes is still there ? Can u please help
Did you delete the code ? Same thing happening to me. No engine light anymore but the code is still there
You can’t delete the permanent code. The vehicles to clear it after the issue has been fixed.
Great 🇯🇲
Thank you
kool thnaks brother,,very educational,,,,,learned ton....
Glad to help
I have a 2011 Nissan Altima! I fixed my mass airflow and o2 sensors. I drove from Los Angeles to Vegas Way over 200 miles still having permanent codes. Maybe I’m not cold starting idk it’s Really frustrating cause the car Runs Smooth as Butter
Yes, you will need to complete some cold starts plus drive for a little while reach time.
They need do what I told in this video
th-cam.com/video/PMcJtcSOzdk/w-d-xo.html
Thank you for the info and tips ..its been challenging to pass my smog on my 2012 Toyota thundra i fix whatever it was on a po456 code ..i cleared it on my pending code got all the ok on all the monitors believe me i did all the endless mile driving cycles.. when i took it to retest smog they said it still fail on a permanent code at this point i giving up..they said to drive more and do more start ups..any advice would help thanks
So you have a permanent code with all monitors ready?
@@RANDOMFIX yes I did.. P0456 at first it was a pending code I ran the drive cycle all monitors were all ok and my secondary air monitor showed inc and I know it was ok but he mention I still had a permanent I need to run more miles to pass smog and in fact I did a warm up start in the morning my secondary air showed "ok" on my obd I was very confuse what the smog tech wanted I to pass my smog
@2010nvillanueva he wants the permanent code to be cleared. Obviously your vehicle needs to learn the issue is fixed to clear the permanent code and he wants all the monitors to be complete or showing okay.
@@RANDOMFIX i need to drive more of the cycle to clear permanent code
Yes, cold starts, let warm I for 15 minutes and then drive around town as usual for 5 to 15 minutes so the vehicle detect the issue has been fixed. What repair did you make?
I have a 2013 Lexus RX450H. I have driven it for 10,000 miles. The perm. code is still there "replace hybrid battery". All we did was plug it out(the hybrid battery) and plug it back in while the vehicle was on. No stored code or pending codes and the car drives fine. any thoughts?
Do you have a oe level scan tool? That will allow to see the Toyota side of code. Have you been to dealer yet?
@@RANDOMFIX That is my question. Why should I need to go a dealer for that? The fact is I have two of these cars and they both have this permanent code that wont go away. The dealer wants $540 just to check it out. Unbelievable!
My cel went on because of a loose gas cap triggered p0442. Fixed the issue erased the code. Have driven the car for 9 days to work at highway speeds and I still have the permanent code that won't erase.
What are you driving? Just like for setting the evap monitor, keep your fuel between 1/4 to 3/4 and park on a flat surface. Start the car and let idle for 20 minutes and drive around town for 5 to 10 minutes normal driving, speeds of 25 to 45
Best way to deal with this, move to a state with no motor vehicle inspections, I.e. Florida
Lol, that would diffidently fix the issue. Yeah, just wait for it and those no emission states like Florida and Arkansas state will follow in ten years. These parameters will get stricter and stricter.
I have this issue with my 2011 Dodge Ram 1500 4.7l. It has 3 codes and 2 codes for throttle, which I've replaced twice, and they never go away. I drove the truck for about a month with no issues, and then out of nowhere, it came back. The other code is for incorrect communication received by the ECU. I've been dealing with this for almost a year and still can't get it to go away.
Sorry to hear about your issue. Your not the only dealing with the crazy bs. I have a dodge as well and had all sort of check engine lights for no reason. I was getting ready to fix them when I realized that my battery was on the weaker side. After replacing the batttery all the issues went away. Is that your issue as well? I don’t know but play close attention to it and make sure you a good ground. And be aware your vehicle this dodge 4.7 is known for issues like these and might under some sort of recall or exception. See if there are any tsb issued for this on carcomplaints.com
Keep me posted and lastly just know that ecu could be bad and don’t cross that off your problem list yet until you test it. I would unplug the battery for 24 hours after confirming it almost perfect. Then reconnect the battery and start all over. Keep me posted.
I changed new spark plugs on my prius gen3 , all are fixed
But still can’t clear code permanent on ODB 2
How to clear? Or wait till after 200miles will auto clear?
Yeah, just try clearing it once and the code will still be there until the vehicle confirms the issue is gone. So start the vehicle and let it idle, since it’s a hybrid let it idle with ac for about 30 minutes as the engine will only run very few minutes unlike a regular car. After that drive it around town for 10 miles or so. You may have to do this 15+ times but it might clear sooner. What was the code for ?
@@RANDOMFIX prius 013 P0302 misfire 2, status :permanent
At the there is nothing for permanent codes,
You said to see the whole video if there is permanent codes,
I buy a 2012 nissan crappie versa, two months and no check engine light but permanent codes still there I cannot pass smog to registered, already spend 1500 on repairs for nothing.
Hi Anthony, sorry to here about your Versa ( if worst started with a v. Vorst ever random silly automobile) issues. The code will only clear if the vehicle detects the fault is cleared. You could for 6 months and the permanent will hang around. Please follow the directions left the vehicle warm properly and drive around town with regular driving habits. You could of inverted this issue and maybe the seller sold if that reason or you the smog was a fake. I hope that helps and Happy New year a day to late.
I have mass air flow sensor code. Do i delete the code then switch to new sensor or do i switch to new sensor then delete code?
Install the new mass air flow sensor and delete the codes. If the mass air flow sensor throw a permanent code then the vehicle will have verify that is no longer an issue.
Thank you very much 🙏
I need to know if my permanent codes have cleared yet. I have a scan tool- 20 bucks- cheaper one.. SHOULD it be picking up the permanent codes IF they’re still there? I’ve heard it can take a month to clear after issue is fixed.. Been told “it should”.
Sorry for the late reply, yes it should display that permanent codes. Any updates?
@@RANDOMFIX yes. It does show them but it’s under the DTC menu. Not under OBD. It will say “INC” if it’s not ready. Mines not ready unfortunately. Been at sea for two weeks so truck hasn’t gone through enough cycles yet. And thanks for the reply. Useful info for anyone in the future. That’s how to see if it’s cleared yet or not. OBD will say all pass.. DTC menu will say INC. until that’s gone, no pass ….
@@IAnonymous3 - You are mixing up Permanent codes and monitors. Your monitors are incomplete, that does not mean you have or do not have a permanent code. Permanent codes do not have anything to do with your monitors being ready.
@@stevew9563 okay. My mechanic said I had to wait until those were gone to pass emissions… smog.. California. Said you can have any Incs. That was the problem originally was permanent fault codes I’ve been waiting for them to clear they may have cleared by now.. but those INCs are still there…… not sure he to get rid of them.
@@IAnonymous3 - The "INC" or Incomplete are your Monitors, Yes those have to be complete in order to pass smog (Except EVAP in CA) . But make sure you are looking on the "Monitors Complete Since Last Code Clear" screen on your scanner. Not the "Monitors this key cycle"
Monitors are not Permanent codes so don't mix up the two subjects.
Does this code reader work for 2014 + rams
Yes, all 1996 and newer obd2 vehicles.
Will leaving the battery disconnected for a couple weeks not clear all codes ?
Nope you can not clear permanent codes. This applies to 2010 and newer vehicles. The disconnect trick was successful with older vehicles.
My question is if you have a permanent code but you’ve already fix the issue it’s resolved itself and you reset the check engine light and go on a 50 mile drive but before you even leave the driveway the check engine light comes back on and it just shows the permanent code and the pending code does it still need the 200 mile drive to permanently clear the code or is the issue still there
If the code code reappears before you leave the drive then the issue is not fixed.

Sometimes people fix it not knowing there is an underlying issue.
I’ll have the same problem with my truck 2016 Silverado it has a permanent code I went to get it smogged but didn’t pass they give me one code is P050D ? Any help plz idk nothing about cars
P050d is generic code
What does OBD-II fault code P050D mean? OBD-II Code Decreased engine performance is defined as a Cold Start Rough Idle. The engine control module (PCM) monitors misfires on initial startup. When the PCM detects a misfire on startup, the PCM will set code P050D.
How is your vehicle running, please provide more insights about what happened and you did to fix some of the issues.
@@RANDOMFIX it drives normal starts normal but jerks a lil bit when it goes up in a hill or passing a car when I step on the gas does that ?
Was your check engine light on?
Did they actually perform a smog check? Or just pre inspect it with a scanner?
just so funny that the are extremely strict on those errors instead of measuring what's coming out the pipe ! And then let other vehicles modify their mufflers and blow out shit.. :(
yes, this whole smog test is funny now, it's taking good cars off the road.
I have a permanent prompt displaying on my 2016 Colorado 2.8L Duramax. It reads:
“Emission System
See Owners Manual Now
132 mi Until 65 MPH Max Speed”
No check engine light/DTCs are present. It did have a temporary DTC of P20BE but it cleared itself after some time driving and hasn’t came back on. Ive driven it well over 150+ miles. This all happened after sub ZERO temps and -20° windchills. No issues with truck prior to cold snap AND it still is starting, idling and driving fine. Just has the permanent display as I stated above.
Thank you for your feedback, much apprecated!
Can this scanner be updated
This is an obd2 reader not a scan tool. I has a usb b connect and did come with a cd but I have never tried to do it.
what if i clear the codes multiple times before i get to 200 miles or 15 start and warm up cycles? does this mean i have to start over from scratch and do another 200 miles and such?
You can't clear a permanent code using a obd2 reader or scan tool. It will only clear after your vehicles the issue is cleared.
@@RANDOMFIX then why is your video titled how to clear permanent codes? You can’t. It’s a manufacturer specific code.
@@slavikk6712it could b ignore not clear.
I have a dodge grand caravan 2017, with a permanent po302 permanent po300. I changed all coils, spark plugs, injectors, wiring, break vacuum hose,throttle body and sensors attached, purge valve, all 02 sensors, and still getting these permanent codes!!! I reset with my scanner but the permanent ones remain!!! Ima try this tonight ima hop on the freeway and drive away in hopes of getting these codes deleted for good!!!!
Hate to break it to you but permanent codes do not mean there is anything wrong with your car. They would be better be called "Verification" codes. Meaning they are only there to verify your repair has been made correctly. Do you need to pass a SMOG test in CA? If not stop trying to fix anything. Nothing is broken. Ignore Permanent codes.
@@stevew9563 I know thanks to this video I understand that now!! LOL I think my problem was fixed when I got new spark plugs, and coils, but I didn’t know that the permanent codes needed to be reset by driving 😩😩 so I kept fixing things and fixing things, I even went as far as fixing two mounts that were out of shape, one was broken so it’s okay that I fixed it!! but indeed I panicked and stressed badly these last 2 weeks!!!
@@izzyn4315 - Well you are not alone, happens all the time. Terrible name for those codes!!
Glad to help the video was help and it sounds like your vehicle is much better shape with all of we parts. That is p0300 is tricky code as it’s random misfire.
Hey buddy I have 07 jeep compass scaner tools says permanent code not supported
Permanent codes did not start in most cars until 2010.
Thanks for helping out here, yes you are right about the pdtc starting in 2010.!
So even if I still have the permanent code and I drive over 200 miles and cold start the truck over 15 times I will pass? I just failed for a p2609 air intake heater code... has nothing to do with damn emissions. Just a permanent code since it's cold here.
Unfortunately a code is code and will keep you from passing. The 15 cold starts with 5 to 10 minute drive will erase the permanent code and once you have all the monitors ready try again and your will pass.
CAT Not ready? EGR Not ready?
Driving over 200 miles did NOT work! Here is what worked: in morning warm up car for ten minutes. Rev car to 2000 for two minutes. Drive at 50 MPH for ten minutes. No cruise control no AC. Then let go of accelerator. Don’t step on the break. Let car slow down as much as possible on its own. To check if car is ready for smog use code reader or turn car on (two clicks) not engine and look at Ck engine icon: if it stays on then go away you are good. If it blinks then your car is not ready for smog Ck. Hope this helps. I have been killing myself to solve the issue.
Hi Jacky, thank you for sharing, this video about permanent mode 10 codes. The drive cycle you shared is similar to
th-cam.com/video/jldTJI64cfM/w-d-xo.html
By the way what are you driving?
I am goin on 4 days and I still have a pending code and I have 2 more monitors to be cleared so I can pass my inspection, do I need to drive it more
Pending code or permanent code?
@@RANDOMFIX yes I had cleared the check engine light Since I replaced the part and after 4 days I seen on the obd2 showing pending code with 2 more monitors still not ready, can the part be bad
If you cleared the code after the repair and it’s still pending that means the issue has not been resolved and you need to fix the issue. What was the code and what did you replace?
@@RANDOMFIX I replaced code p0411
Secondary Air Injection System Incorrect Flow Detected I thought it was fixed Since the check engine light never came back on. But its still showing pending code so think in the morning it’s going to show a check engine light.
Sorry I don’t understand. You reset the code or replaced the secondary air injection pump?
My mom's 2006 nissan quest keeps having a pending code even immediately after erasing all codes. Then once the car is turned on and off, the check engine light pops on
You have an open loop issue ( the vehicle is able to detect the issue right away because of this.) you don’t have a permanent code as your vehicle is a 2006 and permanent codes only affect 2010 and newer. This will better explain it. th-cam.com/video/kVPSEQsvMOk/w-d-xo.htmlsi=42URGrUswlRLgCMO
This will help you with you drive cycle th-cam.com/video/s9PLkO-CjZ8/w-d-xo.htmlsi=ose2JkK8J65uwgru
But you need to fix the issue that is trigger the check engine light first.
I have the P207F code how do I permanently clear it.
Do you need to pass a state inspection? What state? Is your Check engine light on?
@@stevew9563 Florida. No our state inspection is them looking at the vin to make sure it matches some paperwork they do not care if the car works 😂
@@salimrollog7327 - Don't sweat a permanent code then. Nothing to fix.
i got a permanent code but it also says archive inactive .is the code still something I need to worry about
What sort of scan tool or obd2 are you using? I haven’t seen an inactive permanent code yet.
@@RANDOMFIX I have a bluetooth OBD scanner and I used an app called CarScanner on iPhone.
It says:
P0430 Archive (inactive)
Catalytic converter system, bank 2 - efficiency below threshold
Catalvtic Converter System Bank 2 Efficiency Below Threshold
Status: Permanent
I assume that this is a permanent code that has not been cleared.
Do you have to pass an emissions test anytime soon? if not, now worries, ignore it.
@@stevew9563 No, this is actually a car I want to buy from a dealer and I found out the codes after scanning the car. They jump start the car because the battery was bad and that’s why the code is inactive? Because it shouldn’t be there if they addressed the problem? Thank you.
I won’t buy a car until all the drive monitors are set. Have them replace the battery unless you can very yourself that battery is a good by putting it on a load tester. This will be challenging with some dealers.
The real question to ask is why is the battery died, is it old? is there a short? You don’t want to be owner of a dealers dead horse. Proceed with caution.
Permanent codes are caused by constantly clearing DTCs without fixing the actual condition.
When the ecu fails on a code that was just cleared, after a number of times...it goes permanent.
Then, only the ecu will clear the code when a good condition is measured enough times.
That's it.
Thank you for sharing, great information
But how long do I wait before light comes back if problem persist
If you clear the code and complete the instructions in the video the light will not turn back if the vehicle goes the parameters and determines the problem is fixed.
@@RANDOMFIX ok so did that not sure how many times should I wait before I know it’s good
It's in the video, 15+ cold starts with a 10 minute drive each time. It could clear sooner if the vehicle is able verify the problem is fixed.
I have a 2012 Camaro LS and have a permanent code preventing my car from passing smog. Driven 15+ times, over 400 miles and smog place said the code is still popping up and not passing. Not sure what else I can do. Driving with expired tags.
Original problem was just needed a new gas cap. No check engine light since.
Where is your shop location ?
I left the business long ago in 2016 but found lots of people asking me how to complete a drive cycle so I made these 60 plus videos on the top. I will release another smog related video in the next day or so.
My p0442 for ford permanent code won't flash the check engine light but is still on the reader ... I had 50 start ups and 500 miles but unfortunately my battery died so now it reset... frustrating situation( I'm doing the drive cycle as best I can) but it still won't clear
Does not matter if it clears unless you need a CA smog check. Do you? If so then you need 200 miles and 15 warm up cycles and the smog computer will ignore the Permanent DTC.
Thank you for your feedback, much apprecated!
Are there circumstances under which a PDTC will not cause a vehicle to fail a Smog Check inspection?
Yes. PDTCs will be ignored if the vehicle has completed at least 15 warm-up cycles and been driven at least 200 miles since its OBD information was last cleared.
I Neil, I’m not sure if you Asking a question or stating a fact. This was true in the past but now a pdtc will cause a fail unless it’s is known to be an inherent defect as I stated in the video. You can follow my experience at the smog shop in 2022 and the recent updates in this video.

@@RANDOMFIX - Come on man that is not true.The 15/200 rule still applies.

@@RANDOMFIX - You wrote: "This was true in the past but now a pdtc will cause a fail unless it’s is known to be an inherent defect as I stated in the video."
A PDTC will not case a fail as long as you have 15 Warm UP Cycles and Driven 200 miles. Just like the OP said.
Steve, you have a good point but I go off what the tech told at minute 12:03

Maybe I misunderstood him? Please clarify you know differently as I this would help a lot of people who end up driving around burning expensive gas. I appreciate you letting me know nonetheless.
Do I have to let the car cool down 8 hours? I actually live in my car and I have a O2 sensor not ready and the evap not ready Everything else is ready I replaced the battery about two months ago and I drive daily but only like five or 6 miles, I do idle alot To run the air conditioning I don't have a engine light on, I do have one permanent code leak detected but I actually repaired it I found a hose that was cracked in half and I replaced it but that was like 4 months ago.. I'm not 100% sure if that's going to fix the leak but I would think so because it was a decent size.. But the code is still permanent I cleared the code because I had to replace the battery for a few months ago I have emissions test due October 15 I just went today and they told me two of the things aren't ready I don't know why the O2 sensor is not ready makes no sense to me... But yeah I fix the evap small leak It was literally a hose to the solenoid on the top of the motor I found it out when I replaced the water outlet a few weeks back I also disconnected the battery a few weeks back so maybe the monitors aren't set because I haven't been driving very far about 10 miles max a day nothing really over 50 miles an hour , It's a Mazda six 2013 .. I did buy a scan tool today and I can clearly see it there in the red those two and I can take live readings while I'm driving my dash radio has all monitor is too but it's only for like the RPM and speed and gauges and stuff it will throw engine codes if I ever get them.. But the two permanent engine codes are for the evap leak.. Hopefully that little hose is all that was leaking.. I did go on the line and didn't see much but it was open to the atmosphere for sure.. When the weather was cooler I would smell gasoline when I had the heater on to the outside so it was definitely coming from the engine compartment top that location where that cracked hose was... Anyway I guess I'll keep trying I just don't know the proper procedure for Mazda six 2013 four-cylinder would be exactly everybody has a different drive cycle they should just have a reset button that you can press... I have to October 15 To figure things out I'll check the thread later to see if anybody answers..
Yes you will need to start with a cold start which is 8 hours or more resting. Try letting the vehicle rest in a non garages area if you live in very hot climate. I am learning that certain parts of the country like Texas the garage is 95 degrees plus 24 hours a day.
Focus on long warms up and drive around town between 45 and 35 and try coast as much as possible. You will have to do this 15+ times. Good luck and keep us posted on your 2013 Mazda six.
The 8 hour cool down is really only for the EVAP, you don't need that really to pass. All you should worry about is the oxygen sensor. I will post a pic of the Mazda drive cycle. not sure it will post though here in the comments.
i.imgur.com/9HT8vuH.png
@stevew9563 he is trying to clear a pdtc it advised to left the vehicle cool down but you maybe right. Better to be patience than to do something that will solve the issue. There is nothing wrong with letting the vehicle cool down.
@@RANDOMFIX - Well have to get the O2 monitor ready first. in the time it takes to do that you could get the 200/15 taken care of. But pinkie will have to get good at reading his Scanner to see the 40 degree temp drop for the completion of the warm up cycles. That does not take 8 hours. Maybe 1-2
Is Thursday going to be Mo Milla?
Not sure what your saying : (
yes, anyway to get combustible off the road a $maker for the future I hate permanent codes they are time consuming for sure :(
Sorry for the late reply, I appreciate your feedback
so this is a problem for all new cars then ??
Yes, this will be a major problem for 2010 and newer vehicles. Sometimes there is an actual defect and the owner is not at fault but we are stuck trying to fix. I'm there is some poor guy for $$$$ right now for a repair that can't ever be corrected without replacing the engine control unit. I hope every checks the list of defective vehicle first before pay $$$$.

Drain the battery of all power 40 min all codes will be gone.If not power to store the code how would it save anything. 😊
Nope wont work for Permanent codes in 2010 and newer cars. But there is no need to clear permanent codes they are not hurting anyone. Only reason they matter is for a CA smog check. Other than that ignore them.
@Steve W I got the permanent ones removed by draining all power no codes I had miss fire cly 1 permanent it cleared all of them.But if it happens again the check engine light will.come back on.
@Steve W I have a 2011 honda odyssey worked removed all codes even permanent ones.

I am ase certified, What I have done was disconnect the battery, touch battery cables together, and turn on lights for an hour. Once done, I reconnect the battery and permanent codes clear out. You can also disconnect the battery and then unplug the ecu. Either way worked for me. When the vehicle is turned on, it will go into learn mode until you drive it, and parameters will return to normal. Do so at your own risk

Sometimes even after you fix a problem in a modern car the code won't erase.
yeah its a stored code on the computer so USUALLY it will come back i believe the only way to get it to go away is to purchase a new ecu
Not a good video. You are conflating two different items. Permanent code process and drive cycle. The 15 warm up cycles and 200 miles does not clear the permanent code the smog machine just ignores the permanent code after that. The permanent code can still be there and still pass smog.
And the 15 warm up cycles and 200 miles has nothing to do with the Drive Cycle. You can do the drive cycle and complete your monitors in 1-2 trips if you are driving according to the drive cycle.

Hey brother I have a 2010 prius replaced the hybrid battery I still have the permanent code P0A80 please help
Who replaced the battery? Make sure the filter and fans are working and not covered in dog hair or dust. You should clear the hard set codes and see what happens. If this is a permanent code then the vehicles needs to confirm the issue is fixed.
Good luck and let me know what happens?
Did they clear all the codes after replacing the Hybrid Battery? If so get 15 warm up cycles and drive 200 miles. If the only code you have at that point is a permanent code then you will pass a smog check with the Permanent code in place.
It's OK to have a permanent code as long as you are not needing to pass a smog check. A permanent code does not mean anything is wrong with your car. It means something "Was" wrong with your car.
