Thank you Im in Mexico and I try to take it to the dealership here in mex and I can’t because my car is American and your vídeo saved me time and lots of pesos you solved my problem nd I got it fixed with $35 US dollars ☺️ thank you
3:26 throttle body, this needs to be cleaned with special spray and maf/map sensor located next to it. When diy that procedure you will need to do all things together to warrant trouble free engine running for the next 50-80k miles, than cleaning again.
Throttle body clean
Intake manifold clean and map sensor
Pcv clean and inspect, replace if necessary or if the car over 100knmiles
Egr valve, cooler and pipe clean
All metal gaskets can be re used but the rubber one on intake manifold must be changed.
Good video 👍
Tip. Use an old tooth brush to clean out the EGR tube along with brake /parts cleaner spray. Use a 12D common nail to clean out the small EGR tubes in the manifold ports. it is a perfect fit. After using it I reamed the hole out with a drill bit. I had a simple dish plastic bristle scrub brush, dipped in mineral spirits to clean the manifold ports. Used a metal wire brush dipped in mineral spirits to clean the engine block ports. Nice video. Easy to follow. Car runs like it is right off the showroom floor.
Great video. I cleaned the manifold(2 clogged ports) removed and cleaned the injectors, and replaced the pcv valve at the same time. 240k miles and runs great. I had a P0300,P0302,P0304 and P219A and they were resolved with the above mentioned repairs.
Hi how did you clean injectors?
This should be a 50,000 mile maintenance on this Prius generation really helps on fuel economy and brings back power also I used steel and plastic brushes but if yours is more of paste like I found that a plastic brush is better to used because the steel brushes are harder to clean and this gunk gets stuck on the steel brushes but the plastic ones can be clean a lot easier I bought my brushes at harbor fright
I used carburetor cleaner to clean out the small ports. Took 4 bottles of carb cleaner to do the job. 100k miles later I have to do the job again.
😳😳ужас
надо чистить каждые 30-40т
A couple weeks ago I replaced my EGR & PCV valves, cleaned the EGR pipe and cooler, cleaned the intake manifold, replaced the MAP sensor and I'm still getting the P0401. I followed a video from NutzAboutBolts and they overlook the existence of the separate EGR passages in the manifold!! I'm now going to remove my intake manifold again to clean those passages. Hopefully that will fix my issue. THANKS A TON FOR THIS VIDEO!!!!
Did it work? Same issue here
@AlvaroRodriguez-my4ur I ended up taking my car to the Toyota dealer and they found the EGR valve I had installed was intermittently working. It wasn't OEM. Last time I buy off brand parts.
@@BadPhD777 damn, thanks for the reply though
BUY A BRAND NEW EGR VALVE ALONG WITH INTAKE MANIFOLD! YOUR PROBLEM WILL GO AWAY
This is all the governments doing. These engines would last if it wasn't for the EGR
Hand twisted a 7/32" drill bit in the small ports. Worked well to break loose the crusty stuff. Loved your technique to keep the hoses attached on the throttle body. I followed a different video that recommended draining the coolant - wasteful!
great video with great details. It is good to know the coolant lines do not need to be removed.
You’ll want to run a can of Royal Purple Max Clean at your next fill up. It’ll do a great job of cleaning up your injectors and combustion chambers. You should notice better starting and smoother running of the engine.
Personally, I’d also remove the crankcase breather tube; plug it on the box and put a cheap filter on the valve cover. The hybrids get a lot of buildup on the intake side.
Have you done the vent to atmosphere pcv on your prius? I was under the impression the system would read that as a vaccum leak and the car wouldn't run. And yes i mean with the intake side plugged.
You are on the right track.
But you should have also
1) replaced the pcv valve
2) cleaned the egr pipe
3) cleaned the egr stainless cooler
My 2010 with 170,000 miles runs like new after all the above.
Still burns oil though 😥
I replaced the pcv valve before I cleaned the egr valve and egr cooler 5 months prior to doing the intake.
How much oil burned? My 2010 Prius burns a quart every 3,000 miles and never replaced PCV after 185k miles. Toyota says normal to burn a quart in as little as 1200 miles.
Some models have a recall on piston rings.
@@mikeflores2000 2010-14 Prius had bad rings. If the car burned more than a quart every 1200 miles, Toyota would change the rings and pistons IF it was still in the 5 year 60,000 mile powertrain warranty. 5 years expired in 2015 for the 2010 models; 2019 for the 2014s. In mid 2014 Toyota did a production change to the new pistons and rings. So some 2014s are better as are the 2015s. The gen4 Prius in 2016 has a reengineered engine, egr, intake, cylinder cooling, etc. Much better hybrid system used across the Toyota product line today. Only the upcoming Toyota Crown (replacing the Avalon) has the newest gen6 turbo "Hybrid Max" system that has well over 300 hp.
Very useful and coherent video, sir. Seems like my rough engine idle may be related to carbon deposits. Thanks!
Did you fix it what is your driving style since it only happens to few Prius wondering driving style city or highway driving might contribute to Egr build up?
@@ceylontea5877 Mix of both. It clears up after running a bit. Relatively infrequent now. Doesn’t seem to affect performance so far. Just sounds rough on startup.
Thank you and keep adding more to your Prius maintenance list. All of us Prius owners are thankful for sharing your knowledge during these inflationary times.
I've got more footage "in the can", I just can't find the time to edit the footage into a coherent video. I'll get around to it.... eventually.
Really enjoyed this valuable video. From London. Thanks
excellent. i wish you lived in the UK so i could pay you to do this for me
easy enough as a DIY🙂
I fixed my car!!!! Thank you!!!
Thank you so much for this video!
Good Video, looks like I have a project this weekend. 2012 Prius with 240.000 miles is having the same problem.
My new 2010 Toyota Prius now has 185k miles. During cold winter morning starts the engine would chatter and shake violently worse than a diesel 18 wheeler. The problem disappeared without my doing anything except 6 cans of Seafoam, 1 can per fill-up.
My main concern is my MPG has gone from 50 to an average of 33. Is the throttle plate stuck closed, intake valves all gummed up, fuel injectors bad? I cleaned the MAF sensor.
Changed air filter with washable K & N,
oil and filter every 10k miles. I should every 5k city miles. My transmission fails to upshift likely because fluid never drained after every 60k miles.
I’m running into the same issue currently and after seeing your video I’m gonna tackle this issue as well, thank you for the clear and concise description and process 👍🏽
did it work well?
@@VinayakGovande it worked but then my gasket completely went up so now I decided to put her on sale. She gave me over 200,000 miles so I can't be upset at that.
@@Cambodimerican24 my engine was hitting 260,000 miles with cumulative issues building up. I decided to replace the engine with a JDM engine I picked up in Baltimore. Cost $1200 and most of my Saturday to get it. I already had a Harbor Freight hoist and engine leveler. Cleaned up the JDM engine, shot Marvel down each spark plug hole and turned the engine through with a wrench to work oil down cylinders and rings. Cleaned EGR system, new oil and filter. Pulled old engine, swapped over needed items, dropped in JDM engine. That was March? of this year, it's now Dec and engine been great.
My Prius was in pretty good shape, I couldn't have found a replacement Prius for $1200.
I had the old engine out and new engine in for the cost of the engine, gas to get it, and my time. Started pulling Saturday morning, driving by Saturday night.
Thanks Rob! So many laggy hybrids just need some elbow grease (or a wire brush!) to get them back on track.
Thank you! Have the same problem on my prius 2014. I will do this job in the next couple of days. Your video really helps with the way you describe everything in detail!
Did you clean your intake manifold? Did it fix it?
@@juliocesarrojascontreras5125 I bought and replaced the Intake manifold, EGR Valve EGR Cooler and PCV Valve. They needed to be replaced because there was more grime than I could clean. But it didn't fix it. The problem with these 3rd gen Priuses is that they blow head gaskets like there is no big deal. So everyone that has these issues most likely they have a blown head gasket. Along with these parts that we are cleaning that are clogged.
@@ovidiutim3015 Thank you for your time answering my question. I have heard many people with the same problem (blown head gasket). I'm going to buy a head gasket tester and see. But, I'm sure is the head gasket. Thank you.
@@juliocesarrojascontreras5125 As I suspected it was the headgasket the main reason why the engine was running rough and missfire in cylinder 1. And after taking the piston head down that cylinder was wet and had barely any carbon deposit on it due to the fact that cooland cleaned the piston clean.
I did the job myself and it's pretty straight foreward after you get into it. Takes about 15 to 20 hours start to finish. My prius has 260k btw
@@ovidiutim3015 thank you! I appreciate it. That was a big help 🙏🏼
I am getting P0401 which means EGR insufficient flow. I have cleaned up the EGR lines from the exhaust and the straight line through the intake BUT never thought about the tiny holes on the intake. I am going to check it out because I am still getting the code but my car runs nice and smooth under any loads. I had to go through extensive work replacing the head gasket which is a common problem on these Priuses but I love the car not easy to give up on it. My other car is 2009 Camry hybrid with all the bells & whistles but I'd like the prius better!
Good video. You added some pointers Nuts About Bolts didn't have in a similar video. I did this job once, but only used fluids for cleaning. I'll do it again with brushes. Although, right now I'm not noticing any issues.
Nuts and Bolts does a pretty good job. They probably miss mentioning stuff because they're doing the job and making a video simultaneously. I find myself reshooting scenes because I missed adding something. It all takes time.
very clear explanations.... great video. I am encouraged to take a stab at the intake thing. Thanks!
It would have been nice to change the PCV Valve at the same time.
Changed it 6 months prior.
I have bought a secondhand intakemanifold and EGR-cooler, both wiht a lot dirt and builtup. I soaked them in dieseloil but there still was some builtup. I used ovencleaner and the dirt came loose. I only have to put them on the engine. If you keep your EGR and intakemanifold clean you don't have to worry about rattling, troubelcodes or failing headgaskets
I've used Carb and Brake Cleaner, Purple Power, Simple Green, Oxy-Clean.... I have yet to find anything that rips the carbon/oil build up out of the EGR. Everything is a soak, rinse, blow out, repeat ad nauseum process until it's cleaned to my satisfaction. I'm not expecting to make it shiny, new, and eat off it, but I figure the cleaner I get everything, the longer I can drive before I have to do it all again.
Thanks for this great lesson. I have the same problem. All 4 cylinders and sparks plug changed but still runs rough on startup and miss fires on cylinder 1. This cleaning must be done!!! Hope I can return the 4 whatever they are called that go into the 4 cylinders. Spark plugs needed changing. My prius has 198,000 miles on it. This issue has been coming on for awhile. Time to really fix it. No new parts just cleaning!!! WOW TKS!!!
EGR is closed at startup. I would guess blown head gasket.
@@kshxfkt76pz7 it needed all the built carbon cleaned out of tubes going into the manifold. Tks
How you change out a cylinder?
thanks for this vid. im going to go a step further and just soak the whole manifold (without sensors) in grease cleaner and let it sit overnight
wow that 10mm clip trick though!, i just spent a day cleaning the egr tube, egr cooler and replacing egr. i generally cleaned the intake but didnt look to deep into those smaller holes. looks like i got another project. Holy cow what a difference after the cleaning though.
Awesome video thank you for posting.
this should have been a recall!!! One of the worst Toyota fails in history, affects the lexus model too.
Just cleaned mine....completely plugged 😢
Good video! Some people start with the intake spray cleaner - NOT brake cleaner. Must say safe on plastics. Loosen up the goo- then scrub it away. I would check that egr valve again maybe. Too much crap
Good morning, Rob. I’m in Hopewell, VA and need this done to my 2012 Prius. I used to do this kind of work myself but now am a disabled vet. Do you have any recommendations for Richmond area people who can do this job for a reasonable price?
Sorry, I don't know anyone local. Unfortunately I'm too busy to give a hand.
Excellent, solved my same exact problem!!! Well done.
Lot of carbon for a “green” vehicle
Pumping dirty exhaust gas back into an intake isn't great for the engine.
Any ICE has carbon buildup over time.
"According to TH-cam" - should be put into the Bible 🥳
Shouldn't you also clean out the oil cooler before the egr?
"You've got to get something mechanical up there and ream the crap out of it." Ha!
Do you have to bleed the EGR cooler or use any special tools when cleaning the cooler? My '10 has 135k miles on it, I just purchased it, and I plan to clean the intake manifold, cooler, and EGR itself very soon. Great video! I'm thinking about buying all new parts and replace rather than clean the old ones..
You'll need 10 and 12 metric sockets to remove the attachment nuts and a T8 torx bit socket to pull the attachment studs out of the head ( it's easier to get the egr cooler off with the studs out).
You'll need to drain some of your coolant at the radiator drain. Put a small vinyl tube on the drain opening and you can drain the coolant into a pan without it running all over the plastic splash panels and making a mess under the car. Unbolt the throttle body from the intake manifold, but no need to disconnect the coolant hoses, just let the throttle body hang in the engine compartment.
I used brake cleaner, carb cleaner, Purple Power, Simply Green (all at one time or another) to get the crud out of my cooler, EGR valve, piping, and inlet passages. It was a lot of spraying and scrubbing.
I just bought a JDM engine for my Prius and I'm currently in the process of going over the engine prior to pulling my old engine. The EGR cooler was filled with carbon (surprise! surprise! surprise!).
I bought a product called TSP ( trisodium phosphate), got it at Lowe's, made by Savogran, $13 for a big box .
I put a couple gallons of hot water in a 5 gallon bucket with 2 cups of TSP. Soaked overnight, water was black. Ran Hot water through cooler to flush crud. Dumped bucket, refilled with 2 gallons hot water and 2 cups TSP, repeated for 3 full days. As of start of the 4th soak last night the water in the bucket wasn't black but more of a tea tinge. Tonight I'll flush the parts again, I'm thinking this will be my last overnight soak and flush, parts were getting pretty clean inside and flush water wasn't coming out black.
I'm thinking from now on that's how I'll be doing the cleaning rather than spray, scrub, rinse, soak, spray, scrub,...etc. it was way less work, but then again, parts were off a replacement engine and I didn't have to get the EGR cleaned, back on, and running by Sunday night.
If you pull the cooler, EGR valve and manifold Friday night, soak them in the TSP with hot water and do the hot rinse. You may get by with soaking and rinsing in hot water once a hour throughout the day and have it cleaned and back on by the end of the day without a whole lot of elbow grease. I think the hot rinse with the cooler pressed against the faucet really helped get the stuff out. EGR passages in the intake will probably need to be cleaned as in the video.
There is no bleeding on the system, just top off the coolant tank and run the engine until it's hot, shut down, let it cool, then top off the tank. You may have to check and top it again later, it's no biggie.
There's a procedure to make the engine run where you push start button twice (don't step on brake), set parking brake, gas pedal to floor twice,.... I can't remember the rest, you'll have to look it up, but after about 5 minutes you can shut it off and top the coolant.
Awesome. Thank you for this.
This is ethanol left over. Use costco 91 or shell nitro which has practically no ethanol. Please do some research about ethanol in gas.
Thank you for the contribution of your video don't forget to clean your EGR and cooler it is now clogged up with the leftovers of the remaining carbon chunks you might have missed
Can the intake manifold be washed ?
Thank you for the tip with the clip...
Nice complete and detailed! Thanks
Does your MPG improved after the cleaning? My car only 37 mpg and its a 2014 with 145k.
I drive 40 miles one way to work every day on the highway at 65-75 mph. No change. I average about 38-40 mpg.
That's a really good video and very well explained!
Thanks. Glad you enjoyed it.
I did clean the intake manifold nine months ago. recently it threw a P0401 code. is that manifold ports clogged again or EGR valve /cooler clogged? how long need to clean the EGR passage and port?
Chances are you're clogging. I soak all my EGR parts in very hot water + cleaner, last time it was all weekend; soaked, rinsed (with hot water) , soaked, rinsed, soaked, rinsed, in my laundry room work sink....It's not just a quick shot of carb cleaner down the cooler and you're done. Certain cleaners will cut the oil and others will cut the carbon. I think I used LA's Totally Awesome for one cooler (worked best) and Oxy-clean on other another cooler (worked best), also numerous cans of brake cleaner. I try and get my parts spotless, not because I'm anal, but the cleaner I can get them, the longer it will be before I have to do this again.
Great video 👍 I own a 2016 Scion iM with 1.8 motor sometimes I have a surging issue on acceleration only though ….I’m going to try this ,crazy to say I only have 22,000 miles on my Scion great car no other issues
Suggest removing egr valve and cooler. You use a pressure washer to clean cooler and intake. Just finished this job. Also, replace all rubber gaskets. Clear all fault codes and let car relearn.
Pressure washer? Hmmm... I'll have to give that a try next time. Because you know, there will be a next time.
I thought i was going mad, ezact same symptoms as me, i would let off the gas coming to a stop, and i thought the the texture of the road was becoming rough, i would be stuck at the lights and the car was running rough, i would pull away car would be spluttering untill im over 40mph and would get better, again in the traffic i would have to slow down and have to be right up someones bumper to stop it stalling out very frustrating lol
Did ya fix it?
Hey RobRig, Just ran across your video on your intake for the Prius. After being coerced into doing the maintenance on my Prius I recently changed out the PCV. I did not do the intake although I bought the gaskets anticipating that I might have to go from the top but was able to get to the PCV from the bottom as another youtuber displayed. I'm really curious though as to what type of fuel do you run in your Prius? I know there's a lot of controversy regarding it does or does not matter what type of fuel you run but I'm a firm believer in running only Chevron. Just curious as to what type of fuel you are running?
Costco 91 or shell nitro has practically no ethanol, which is the culprit in leaving this burnt deposit leftover. Those types of gas I use in my prius.
I run 87 octane (with ethanol as is commonly found in the US). It's rare to find service stations with no-ethanol gas, usually they're in rural areas. When I can find it, it's as expense as the 93 octane.
@@sanjeevk1842 I'm aware of the "problems" with ethanol, mostly ruining fuel systems over time if the gas sits for long periods (like in my lawn mower). I've not heard that ethanol causes clogged intakes in fuel injection systems. This looks like carbon and oil (PCV) type of problem. I'm thinking of adding an oil catch can to the PCV system.
Thank you RobRig for the excellent video. I successfully performed this service on my 2011 Lexus CT200h this past weekend following your steps...esp. the tip about the 10mm socket to unhook the plastic clips, not disconnecting the coolant lines to the throttle body, and using cleaning brushes. I used a set from Harbor Freight that were okay...probably could be a bit longer. I also should have started straight in with brake kleen instead of the throttle body/carb cleaner that I used. That was on me and would have saved a lot more time. The CT doesn't get as good of gas mileage as the Prius, but on my first test drive circuit, I got an average MPG of 46 vs 41 after the cleaning. I just wanted to thank you again for your video!
thanks for the feedback. I know others will appreciate the insight in your comments.
Someone have egr delete how to?
Thanks man great job 👍
Except for the price, it would almost be better to just buy a new manifold for all this work.
Except for the price, but if parts were free we'd all just be slapping on new ones.
Hello! Just say you did an amazing job on this video. I wonder how many people would avoid doing an unnecessary head gasket if they saw this. I’ll be sharing. I liked and subscribed. I don’t do that often :)
I'm surprised people are subscribing. I like watching TH-cam vids and people I subscribe to put up real quality stuff and have a schedule of new stuff like once a week. I'm just a amateur doing this on the side to help other people out who run into the same problems I have, whether it's my truck, Prius, Z-3., motorcycle, or some other thing. Just the same, thanks for subscribing, now the pressure's on to get some more videos up.
@@robrig1646 I feel the same way when people like my videos. But try me you’ve got a gift. The way you shot it, the way you explained things, the way you hold attention. Obviously it’s s balance - don’t waste the gift BUT don’t make TH-cam a 40 hour job either haha. I appreciate the video!
@@DrewGarage I already have a 40 hour a week job which is why the vids are so slow in coming. I film the stuff as I do it, then it sits unedited because I'm busy with other stuff.
@@robrig1646 ditto! Sometimes I wonder when my kids watch TH-camrs like “Blippi” ($40,000,000 net worth) if I’ve got it backwards!
@@DrewGarage I think my life is just a series of bad decisions such as: work hard, honesty, loyalty, dedication, paying my bills, not digging a pit of debt, and living within my means. Maybe that's backwards. A coworker once quipped, "I spent most of my money on women and booze, the rest I squandered"
any milage improvement?
Whoa… I need to do mine asap
Great video do you got a video of how the engine sounded rough, before you clean it up the EGR!!!
I don't. I tried to give my best description of how it was running.
Great video to the point!😊
Can this cause a p0401 code even after replacing Egr
I believe so. If you replaced the EGR and/or the cooler and didn't unclog the intake EGR passages you will still get engine issues. Pull off the intake and clean it out like I did in the video.
Thank you. My 2010 Prius with 240K is doing the same thing. I will attempt to fix this over the weekend.
Did you fix it? let us know what you found and how it worked out.
@@robrig1646it runs like a brand new car. Smooth, responsive, and better gas mpg. Mine was exactly like yours- all holes were clogged. I used multiple thin brushes and once I removed big chunks, I used pressure washer to each ports. Repeated the processes multiple times. I’ll probably do it again every 50K miles. I also replaced PCV valve since intake manifold was removed, and cleaned out the valves. This had nothing to do with rattling noises. Thanks.
@@Sagemeister007 That's good news. I replaced my original engine with a JDM engine. I tore down the old engine and found all the piston oil control rings clogged.
I now make sure I change my oil every time the change oil light comes on regardless of the oil manufacturer's claims of "15,000 miles". I also started adding 8 oz of Marvel Mystery Oil at each oil change.
You're probably still gonna get oil through the engine from the PCV system. My old engine was getting oil in the intake and new engine did the same, so I added an oil catch can between the PCV and intake manifold.
If anything, start using Marvel in your oil, it'll help reduce and clean build up on the rings. It's pretty cheap preventive medicine.
I change my oil every 3K miles using full synthetic. It might be overkill but I do it myself so I save money. I’ll try adding Marvel next time.
To clean carbon build up.
Extra strength oven cleaner ingredients sodium hydroxide let sit 20 minutes and rinse.
For oil and varnish use starting fluid.
I recently bought a 2010 Prius with the problems you described.
70 years ago, I used to hang out around a GM truck repair station that was run by a few WW2 Red Ball Express mechanics.
[I pumped gas there.] Everything they did ran fine, courtesy of the US Government and its petroleum engineers.
A few products that worked well then have survived a very long time.
Two are Marvel Mystery Oil and Rislone (extremely slippery). Also, more recently, -- Techtron.
That Prius said i delivered 42.3 mpg for the last 1000+ miles. But I was getting less under ideal conditions, 70F
I tried the best of Rislone -- use with two tank fulls -- The misfire stopped and the MPG rose to 45.5.
After the second tank of Rislone, I added a tank full with Techtron and nursed th MPG to above 48.5 on combined Highway and regular.
Something good is happening, and I'll keep trying to see how much more I can get.
I am driving slower than usual (65 now) and the weather is a perfect 70 degrees.
I'm eager to seel how well that lasts, especially when the fall/winter sets in.
Useful advice: Avoid "crap gas."
All refined gasoline reaches NE through pipelines, where they drain into immense tanks owned by brand names who add adatives.
Gasoline tankers carry two grades that they mix to form three levels: regular, medium, and hi-test.
I put about 180K miles (on top of 60K -- 240K) on another 2010 Prius and always tried to use Sunoco which cost a little more but always seems to deliver 5-10% more miles.
It's all about the adatives.
BTW - Something I noticed recently -- Mobil One has oil guaranteed for 20,000 miles.
Good info. I gotta try the Rislone, see what happens. I do know my Lie-O'Meter always says I'm getting 2-3 mpg better than calculations after a top off vs mileage since previous fill.
As far as 20,000 mile "guarantee' on motor oil, I wouldn't do it. I run full synth and still change mine at recommended Intervals: oil is way cheaper than new engine.
@@robrig1646 20,000 is insane. It is not just the oil that you change, it is the build up of other crap that you get rid of when you change your oil. Even 10,000 miles is a stretch. if you read the Toyota maintanance guide, they put an asterisk where it says 10,000. You really have to be driving pretty much all highway miles to warrant 10000 mile stretch on oil change. If you have harsh winters (half the country), lots of urban city driving, delivery driving, short commutes etc, you should replace every 5000 as per Toyota in the maintenance guide. Even the cheapest oil is better than not changing your oil in correct intervals.
I'm having the same problem with my 2011 lexus ct200h it's like a knocking noise I've changed the plugs and coils
That tip about the 10mm to get the clips. Mind blown
Thanks, I think for a few people, that was the take-away that stuck with them and made watching the video worth it.
I came up with it out of frustration, so I was reaching into my mental bag of possible tool tricks, when I pulled out that one.
When I discovered that little trick, even I was thinking "Holy shit! It worked!".
Then I thought, "Man! I'm gonna get the Nobel Prize for Automotive Discoveries. Everybody needs to know this trick, I gotta share it! I'mma put it in my video!"
@@robrig1646 first time watching you
But I’ve been doing all the work on my Prius
Never thought about using the socket though
Cool, easier to pay dealership $800 though
I suppose, if $800 is easier to come by than a Saturday afternoon.
Having this issue on my 2014 Ford Fusion Hybrid, ignored it because all the mechanics I went to told me my car was running perfectly. Now I have an atf and oil leak, if this happens don't ignore it.
Im in Powhatan not far from you, thanks for the detailed video! My Lexus CT200H is exhibiting this issue.
Hats off to you sir. Very helpful.
Thanks

Will GDI cleaner just work?
Don't know. Try it and let us know back here.
In this video we are talking about crap 😂.
Yes we are.
Any rough running and it could lead to blown head gasket. I have cleaned everything then unplugged my EGR valve. The design is bad and could cost you a new engine. Does it contribute to higher emissions? Maybe but not near as much as building a new engine
Pls I seriously need your help. My location is Nigeria. There are no mechanics here who can really work on hybrid cars.
For the past 2 months, I have been having rattling and knocking sound. With no error codes. I cleaned the whole egr systems, cleaned injectors, changed spark plugs, cleaned throttle body, cleaned PC valve, Cleaned inlet manifold, I have oil catch can installed for about 5 months now. Upon all these, the car is still rattling and making knocking sound. Especially when it's charging the HV battery.
If I drive fast the sound disappears.
My coolant doesn't shot, my engine oil doesn't have water in it but I noticed the oil does shot. So I can't say it's blown head gasket.
And today this new incident happened.
Now if I remove the 12v battery head for 5 minutes and put it back the car starts on ev only after 3 to 5 seconds then car trys to start the engine and the ready light goes off and check hybrid system light and other error lights comes on on dash board.
Is this a sign that my engine knocked?
Will Changing the crankshaft position sensor solve the issue?
What exactly should I do?
The car has 145,000 miles on it.
The error codes it shows using toyota techstream now are P0335, P0A0F, C1259, C1310
This is how I repaired my Auris 2011 hybrid unfortunately after I have replaced the EGR and the cooling radiator before the EGR valve. All the small holes from the air admissions was blocked. I'd you get an EGR fail please clean all the way to the admission chamber before replacing the EGR
I have a 2012 prius. With 206.000 kilometer per on it. With how much kilometers will this happens?
nice video Rob
At this point, I’d just buy a new intake manifold
What about a egr delete to stop this from happening
I don't know, may cause other issues. The fix is simple; Just take the parts off and clean them.
This is a great video!!! So the EGR cooler is a problem also, not just the valve itself?
You have to do the whole system, from exhaust end connection on cooler to intake end at head ports.
@@robrig1646 OK thanks
goodnesszzz
Hi Rob, I am in your area if possible can you look at my Prius 2011?
Hi sir i do this pruceger all.but the car is nocking and hove chek light on and code have selander 4 micfair
Nice house
How many miles do you have on this car?
Something like 250-260,000 miles at the time I did the video, but engine had been giving problems for a couple year before I shot the video.
Did that on my 2014 CT200H which uses the same engine as a 3rd Gen Prius @80,000kms (SYD, AU). Being the first time cleaning, there was hardly any carbon deposits on the intake manifold at all. Not sure if the fuel i used had anything to do with it.
Tks so much. My 2010 is doing same thing.
thx thx love you
Hi my prius have a problem it makes strange noise and showed up the axsaust light every time can you guide me what would be the reason?
Do you drive a lot in the city or highway in your prius?short drive long drives and what average speed in Highway?
I do 80-100 miles a day to/from work, at 60 to 75 mph. That's easily 90 percent of my driving.
My Prius will use lot of oil if I drive past 66 but does not use any oil if I drive 58 to 63mph.
Anyone ever try Seafoam for these issues?
You mean run it in the engine oil or fuel? I have, it doesn't do jack to clean out the EGR system or keep it clean.
If you mean soaking the parts in Sea Foam, it will loosen and soften the gunk, but you still have to scrub it out with mechanical means; Sea Foam is not a magic "soak it and rinse it" solution.
The clogging of the EGR system is inherent in these engines; it's just a matter of time.
Woahhhh brake cleaner is not the way to go i strongly disagree with that. When it comes to intake system a lot of mechanics do not recommend it
Thank you, very nicely explained
Thanks for letting me know I have been lacking in the maintenance of plugs, egr, air filter. Will be buying a few things for the car.
Will be giving this a go, I have the same issue.
