Thank you very much for sharing your knowledge. I cleaned the throttle body of my wife's NIssan Note. It gave me a hell of problems, engine riving at idle. I followed the procedure on the service manual but couldn't solve the problem. I sent the car to Nissan dealership, they could NOT fix it with their ScanTool as well, but told me either the ECM or ETB(Electronic Throttle Body) is defect. I drove home because letting them change the ECM or the ETB will cost me a fortune. I ordered an ETB whose manufacture has a good reputation. With the help of a Scan Tool I bought, and your trick " brake and Gear" in position, it finally worked.
Jesussss . The way you explain calmly makes me wishes you to be my mechanical lecturer.
What the hell Jesus name got to do with your problem there millions of words to use leave his name out of your vanity mouth.
@@darrinfaulkner8911😂😂😂
These should of just stayed mechanical
Certainly things today are unnecessarily complex under the hood
I'm from a family of mechanics. This is Small talk for many of us. Remember the days when you opened the hood and all there is was a battery and engine. Not a ton of plastic spaghetti and sensors. Argggg 😤
Thinking the same thing
Yeah if you want less performance, then sure
@@edocsil1635 and greater reliability? Definitely. I like that trade.
The most helpful video ever lead me straight to the problem and didnt just throw multiple possibilities where I’d get lost thank you 🙏🏿
MY MAN……. Thank you so much! You helped me figure out that the new motor and trans I put in my 07 trailblazer was as good as I knew it was. I had some things going on that I just could not explain to any of the other techs I worked with, and yes I did try to clean, relearn and had the computer flashed as well… nothing worked, so I found this video and fixed my 2 year old headache. Again thank you so much!
What was the issue?
I got a 07 trail blazer too it got crank just no Start after I get it to start I drive it about 20 mins and it leave me there
This nick guy's comment makes no sense 🤦♂️
Thank you so much for explaining this in great detail. I recently got the throttle body swapped on my 2020 Versa and I left the dealership and 10 miles away, the car began to shudder. Eventually the engine shut off and their excuse was "it didn't take the programming" I had to come back for the relearning.. The dealership drove it 20 miles instead of the previous 3 miles when I got the car back a second time. So far, it looks like everything is holding up.
Bro you the best man, - wish you were in my area. i'd be over with biscuits and a notepad lol
I'v replace the throttle body 3 times on my 2008 chysler 300, cleaned them as well. Someone told me its the throttle body sensor that need to be replaced. I dont know where the sensor is located. I found the part on rockauto. So will you please make a video just about the throttle sensor and how to replace it.
It’s Throttle Position Sensor ( TPS) and is attached to either left or right side of the Electrical Throttle Body . One side of the Throttle Body is power connector and the other side is attached to it is Throttle Position Sensor ( TPS) that reads and sends information to the car computer the position of the Butterfly ( Blade ) when we press the pedal . The car computer (ECM) accordingly adjust the fuel spray in the fuel injectors .
It is part of the tb... Mabey its the harness / pins / wiring in the plug that goes to the tps ON the etb🫡
I love watching you work on 4 cyl engines GOOD JOB BRO!!!
Thank you Pete. Good job. Have a blessed and safe week to you and your family.
I bought a second hand one. Went to replace it and found a plastic bodywork fitting stuck in the butterfly valve. The air filter was not fitted right. Might be best to have a look before buying a new one.
Fantastic fantastic too too GOOD teacher i would like to learn much more from you
Thank you
Very much
I have a 2014 town and country. Lightening bolt comes on and van won’t start. I cleaned the throttle body and it was pretty clean TBH. Under 70k miles. How do I test the TB or pedal sensor or do I just throw parts?
At 5:11 my mom ride has a check engine light when i used her ride, it's a 2019 chevy cruze and it's has a electrical throttle body her air filter was dirty so replace that and went to check her throttle body but no build up has occurred yet so i still cleaned it but I wanted to see if it was working or not, got my phone out and postion my phone to record the throttle body while I pressed on the Accelerator and once that was done, check the phone and it starting to make noise every time it would open
Thanks for sharing this video on electronic throttle body troubleshooting. It's helpful for diagnosing and repairing engine issues. Great work!
That is an amazingly comprehensive tutorial. Thank you. I have an Alfa Romeo Brera 2.2 Petrol. I’ve lean the TB and it’s now wonderful. Can anyone tell me how to increase idle speed from 8,000 currently to 10,000. How do I do an idle relearn on an Alfa?
Well explained. I have the same throttle; my issue is that the deceleration is weak. It takes seconds or so to return back to the initial position. Do you know how I can fix this?
You are replacing the throttle for the glitches shown on the scope, on the motor circuit?
Regarding the relearn section: I have a Skoda Roomster 1.9 TDI. Would i have to do a relearn for every brand of throttle body, or do some not need it?
Wow such valuable information. Especially since I just purchased a 2005 Mercury Grand Marquis. That is the first year of those cares for "drive by wire" I just learned.
Hello,
I have an Alfa Romeo Giulietta QV 1.8 turbo petrol.
My car has developed a problem with the idle hunting after reseting the self learned parameters of the ECU. The car starts perfect, idles good until the temperature start rising and the engine starts calculating the mixture, than the idle becomes erratic...goes up and down and than stabilizes and than again and than stabilizes. Under acceleration the car runs just great with no issues 🤷🏻♂️. The car has no check engine light on!!!
I have changed coolant temperature sensor, cleaned MAF and MAP sensors, changed spark plugs and coils, going to change the wide band pre-catalyst Lambda but the old one does go in closed loop. The only thing not changed yet is the electronic throttle body. I did try to clean it and was not dirty but I did move it with my fingers. Coul this cause a fault in the throttle body...if yes why it did appear only after the ECU reset 🤷🏻♂️
Please give me an idea what coul be the trouble
Hi guys.... I've got a 2012 Chery J1...i had the same problem but... But I tried a temporary fix which was to use a fuel injector cleaner ...wait until the tank is almost empty... Add a small bottle of Injector cleaner... Approx 150mls.. Add Fuel and drive away. The result was amazing... No more hesitation when acceleration was applied... A more smoother ride.... It's being a few days so far and the car is definitely running a lot better.. What have u got to loose?..
Wow what a great video
Sir I have corolla 09 while driving the car goes off when I try to slow down
Going through similar issues. Changed mine a couple of times, it rev very high each time. Let me know how you solve yours
Thanks for making this Video.
Im not a mechanic and Im trying to get a little old 2006 Honda Accord to run properly.
First issue is it doesn't read the scanner when you connected to the scanner I took it to a couple of autopart stores to used their scanner and it just doesn't work.
The issue the car is as you drive the car for about 15 or 20 minutes the car slows down even if I add more speed and press the gas all the way down to to floor it just doesn't get more power.
I know I need to get that scanner connector fix before I do anything else to the car but watching this video taught me one of many things that might be the cause of the poor acceleration issue
Again Thanks for making this video it was very well made at first when you said that you have to reset the new Throtte I said oooh nooo I need one of those computers to reset it oooooh mannnn but then at the end of the video you showed us how easy it was to reset it.
I said I could do that.
🙂👍Thank Very Much.
Glad you liked it. Your description of the problem sounds a lot like a clogged exhaust. You may want to disconnect the exhaust where it enters the converter and take a look inside...maybe even drive the car with the exhaust open to see if you notice the difference.
You could get a blocked fuel pump filter
I'm a neighborhood mechanic of 15 yrs and my experience with the symptom you describe happened to a Toyota Corolla that had bad slide pins in the front calipers. After about 15 to 20 mins of driving the issue was a bit baffling because the car struggled to increase speed due to these seized brakes! Again, the last area I would've pinpointed because the car had a complete front brake rebuild from a corporate shop the year prior. The slide pins in the calipers were BONE DRY and the rubber boots were not seated properly. This caused the calipers to keep the pistons pressed further out and the brake fluid wasn't returning to the MC all in due process. Needless to say, problem solved and I gained respect as a trustworthy neighborhood mechanic! 👍🏾
Did you ever find out the problem to your car? I have the same issue in 200p Kia Sedona.
Thank you for sharing. 🤝 Your educational content was helpful. 👍👍
Thanks... For the video..
I had a problem with these kinda throttle; it would work when ignition is on and stops when engine is running??!!
Great video, and Duralast is probably great too, but not only that i can't afford it, I would not pay that kind of money for any throttle body! I can almost buy a whole used car for that price! A Duralast throttle body for an 02 Volvo S60 2.4T costs $822.99 at Autozone! Not just an arm and a leg, they want a whole body for that throttle body, lol! What are they smoking?! Crack? I wonder how many units they actually sold and who would buy one at that price? Bosch unit is OEM and it's half the price of Duralast! Now, is Duralast really twice as good? I doubt it, unless it's made by hand mostly out of gold or something. Still can't be twice as good. I like to dream of parts that were "built to last"! :-) Thanks for the quality video, tho...
Oh man if only companies made parts with the goal of lasting as long as possible. I can say with near certainty that they do not, there's money to be made in replacement parts. One day soon, for a thousand years Jesus will rule the nations with an iron rod. Hopefully this is one of the things he fixes
Cause it's a Volvo buy American next time
Hyundai wants about $700 for a throttle body for my car. Duralast is $189 at Autozone, and comes with a limited lifetime warranty (warrantied until I sell the car).
Autozone offers several other aftermarket throttle bodies; but those only have 1 year warranties. I'll stick with the Duralast if I need one (I'm researching possible problems and possible fixes before I start to take things apart). But cleaning the throttle body makes sense as it has over 300,000 miles on it.
Hi bud, I have the weirdest problem! I went to change the air filter and thought to check and clean the throttle body butterfly. It was fully open which I thought was strange as had no real issues, I mean I have thought the car was a little sluggish on acceleration (delayed) and thought maybe my EGR choking. I always put good quality treatment into fuel and try different types so thought maybe not so... Lately had a little stuttering at the first few lights after leaving the house first thing but not pulling off the drive?
My throttle body was fully open with engine off, I sprayed it and wiped but was pretty clean... as you could wish for, I sprayed in with engine running spurts of spray at a time but no movement with butterfly?
I had my naibours grandchild come with half decent scan tool tablet a month or two earlier to check car after I gave him a toe and he said that there was no codes, which he thought was suprising. I dont know if he knows fully whats wha but he mentioned my pedal showing depressed 19% ?? he didnt start the car with scan tool plugged in which I asked and said that I thought you could but he said not with his tool. He said he wiped the car for any codes anyhows. Oh I did have a funny few weeks with my battery dying a while back and got that checked but came back fine (just needs a charge so I bought a smart charger and let it do its thing but it kept dying on me and then I put the battery on a full repair charge and its been fine since plus i've kept car in a lower gear to charge up more as my brother said I was driving like a pussy... trying to save miliage 😂 Any idea bud why my butterfly is full open with no real issue on idle or revs going high and once the car warms up all other issues apart from sluggish accelorator dissapear! oh and I disconnected the battery a few times to charge so I assume the sensor would have reset as ive heard on another vid to disconect the negative.
I have been worried why my surpentine/alternator belt seems slightly worn on the outside but looks great on the ribbed inside? I thought maybe my issues was the belt tensioner or idle pulley but strange how the black is wearing off on the outside and all looked good with no movement on the tensioner. I did hear the other night late on when it was quiet a little rythmic chirp ever so quiet which i've not heard before which makes me think the idle pulley but cant make head way with the throttle body butterly fully open?

Can anyone tell me if the throttle body on a 2004 camry 4 cylinder has the idle air control valve built in? The Chilton manual says both the 4 and 6 cylinder which has a throttle position sensor cannot be replaced separately.
My 2003 Tacoma sr5 stalled on me and gave me a code P2121 - Throttle/ pedal position sensor/ switch D circuit range/ performance. So I bought TPS and it worked for a day. And today it stalled again and gave me code P2138 throttle/ pedal position sensor / switch D /E voltage correlation. Any idea what can it be? Throttle body opens butterfly 1/4 not even half way when I move the accelerator wire that’s connected to throttle body.
Hi, thank you for your insightful video. I have a 2003 Tacoma prerunner 2,7L Reg cab. The mechanic fixed the check engine light due to the dirty mass air flow sensor he thinks? I drove it for three days and I experienced the same problem when I started the truck. The initial start always came with the rough idle then drive fine after that but the engine light came back on. I replaced the mass air flow but that didn’t solve the check engine light. The truck runs fine and the second days start the engine starts with no rough idle…it only starts with the rough idle when I don’t drive more than two days. Any help would really appreciate it. Could it be the fuel injectors gone bad?
What code or codes are turning on the Check Engine light?
PO300,3002,and P03003. Also, I had changed all the Ignition core and spark plugs..did try clearing the throttle body as well..
Disconnect the negative terminal from the battery.
May I ask what you used to clean under the gasket?
My 2008 Escalade 6.2 "hiccups" with varying severity under light load at part throttle, especially when climbing a grade at 40+/- mph and between 1200 and 1800 rpm. No codes are thrown. The vehicle has 210,000 miles on it and I acquired it with 190K. I plan to check the APPS and the TPS; perhaps the variable resistor quadrant(s) have a rough spot? Any ideas would be appreciated. Jeff.
Where are you located sir. This is my exact problem. Thanks
Will this relearn work for an 05 Cadillac CTS?
My 07 VW City Golf Mar 4 (2.0L) Engine light is on and I scanned and was showing P0068 which is related to MAP/MAF. What I want to do is, first of all, replaced the air filter, then clean up the throttle body, my question is, if I take out the throttle body, is it to be reprogrammed or just as you said in the video, just follow your procedure and let it relearn. Thank you.
I have a p2111, code throttle body stuck open. I replaced the throttle body w/ sensor and still have the same code ? Im not sure if itsthe ecm or pedal position sensor, any ideas ?
I have 2010 toyota corolla. similar throttle body top right cornar there is a screw hidden in a glue type material.
can you please tell me, what is the function of that. and how it help in adjusting a specific parameter?
I have observed that changing the position of that screw make throttal pedal to respond differently and effect the drivability .
I have an issue of poor idling. throttle body is cleaned. every possibility has been checked but could not fix the issue.
How I wish I had found this when it first dropped. Replaced the MAF 3 years ago & only drove the Ranger 20 miles before parking it. Six months later it’s throwing the same code. I’m told to drive it over 50 miles an hour for 50 miles & that should do it… it didn’t. Next day found a bird’s nest in the intake. Still ran fine, tho. Cleaned everything out & eventually the code cleared. After moving it around all summer, today I decided to sell it… it started to crank & then nothing. The code is back!
Hi Mr am having a problem with my throttle body for ford fiesta mk6 st 150 2.0l I cleaned it up and then when I the car it only rav once and then stop raving go back to limp mode I bought another throttle it's still doing the same thing the machanic think it's a ECU
Thank you so much for this Uncle. God bless🙌
I cleaned the throttle body on my 2011 gmc 1500 5.3 I start it up N push against the throttle body blade(butterfly)to see if it’s clean in there it pops and shuts off the truck now when starting up have high rpms 2.5k-3k do I replace throttle body ?
Do you have any trouble codes in the ECM or is the Check Engine light on?
@@MotorAgeMagazine l think need to be relearn with my best regards
@@MotorAgeMagazine I have a 2003 sierra and Im having pretty much the same problem except mine revs up to about 4200 rpm and I have a check engine light the code is po122 and it is Throttle/pedal position sensor/ switch A circuit low do you happen to have any ideas?
If you are pushing on the throttle blade you probably have removed the intake air duct, which usually contains the intake air temperature sensor, and/or the mass airflow sensor. You can't expect the fuel injection to work properly without the IAT or MAF sensor(s) in the intake air flow.
Thank so much, great info.
Ihave a 2001 ford fusion with a 2.5 liter engine. My engine light and wrench light came on and threw a 2119 code. ( engine throddle body actuator) and a emission warning. I sprayed and cleaned the throttle body but didnt do a re programming.
I can't find where is located on cadillac xt4 2019
I just bought a 2013 Dodge avenger with a 2.4 l engine and I had to replace the thermostat housing but now the idle is kind of funny so I'm thinking this may be my problem. If I hold the gas pedal down for 2000 rpm's it goes up to 2000 down to 1800 backup to 2000 down 1800. I'm gonna try to clean it 1st but I have a feeling I will have to replace it. Thanks for the video
Thanks for the video!
Can I get help with the diagnosis of my car?
2010 Toyota matrix with 1.8l.
Cleaned the excessively dirty throttle body.
Replaced coil packs and plugs. Cleaned mass air sensor. Replaced filter changed crankcase sensor.
Initial issue was a backfire under the hood that blew off the vacuum line under the throttle body.
Also check engine light sand cylinder 3 and 1 misfire.
While changing the plugs and coil packs, I noticed oil in the number 3 cylinder and a small amount in the number four cylinder. I cleaned a cylinders and replaced the valve cover gasket.
I'm still having idle too high and it fluctuates just slightly about a plus or minus 50 RPM fluctuation while driving and while idling
It was after replacing everything but before cleaning the throttle body that I noticed a new code. P2103.
This led me to clean mass sensor and remove and clean throttle body.
Throttle sensor could be your accelerator padel?
I just replaced my throttle body on my Cadillac escalade esv 6.0 and when I turn the key forward the throttle body is just clicking why is this any help I would gladly appreciate
Thank you for this video. Can i open the throttle body plate with the key on engine off by pressing the gas pedal?
Did you figure out if that's possible the answer to your question is really important for be to diagnose my friend car
@@rocklobstar5672 i did not
Hi thank you for the video, should the throttle stay open when the car is turned off ?
No has to be in close position.😊
My 2004 Acura MDX goes to 3000 RPMs when accelerating from 0 to about 40miles per hour. I need to often take my foot of the gas to let the RPMs go down? What could be the reason? My throttle body has built in mass air flow sensor sensor and idle air control valve if I am not mistaken.
is idle re-learn procedure applicable in 1996 ecm design engine
Not likely
Thanks sir I have Chevrolet Cruze his car RPM not working up to 1500 what problem I am using scanner but did not any code seeing in scanner
In my Lexus Lx470 2005 , I found that when I press the accelerate fully (full gas) it goes maximum only at 2000 RPM and it doesn’t accelerate beyond that. But when I put to neutral it’s goes beyond 2000 RPM.

Looking for advice and fix.
Greetings from Hartford Connecticut!! Thanks for putting so many educational videos on youtube!!! Thank you!!! Tell Pete that I love his videos and that this is one of my favorite youtube channels!! Keep up the good work!!!! Be safe!!!!
Hi, i have an Audi Q5 2.0 Tdi 2010 2 days ago i want to clean the Trottle Bdoy i found it in Open Position ( the Engine was Off) is that Normal ?
2011 fusion continued. I do have a weak battery can that cause the throttle body actuator issue?
That's always the first thing to correct when dealing with any electrical issue or component problem.
Cleaned my TB, and now my idle is jumping 1200-2000 or so but mainly only in neutral, have tried a relearn, and still nothing, 12 civic si, not sure what’s next
Check engine light is on (has been for about a year. Been to several mechanics and no one can figure out the cause), and have now experienced Low Engine Power warning several times. Cleaned the throttle body and reset the vehicle as per this vid. Works for a few days then low power warning again. I drive a 2010 Buick Lacrosse, about 170k miles. What could be going on? Is it time to get rid of it or can I get some more life out of it? Great vid, btw.
The Low Engine Power warning can be caused by a variety of problems. Personally, I would begin with a complete testing of the engine's primary systems - compression/sealing, volumetric efficiency, ignition and fuel. Are there any codes stored (is the Check Engine light on)?
@MotorAgeMagazine Check Engine light has been on for over a year. I've had several mechanics look at it. The car is returned to me with the light off, then it comes back on a few days or weeks later. That's why I've taken it to different mechanics, but end up with the same result. Honestly, I think they're just disconnecting and reconnecting the battery so that the light goes off. I don't know the code numbers. Car is immobilized right now (due to low engine power).
Excellent video Pete. Thanks for sharing your knowledge and videos. Artie 🇺🇸😊
Thanks for the tips how do you clean the electronic throttle body
First, you need to check the service information for your vehicle to see if cleaning is even recommended. If it is, I like to spray the cleaner on a clean rag and then wipe away as much as possible. Some light applications directly to the heavier deposits is ok - just done over do it. You can use cotton swabs to clean around the throttle shaft and the edges of the throttle plate.
@@MotorAgeMagazine please my car goes off while driving or while slow down after a long drive
Good job dude I'm going to do that same thing right now I've been dikkin around with this thang for ever hold up let me try that
Hello! Nice video! Can I have some help? I am struggling with my Mercedes w221 s320cdi. The problem happened when I turned off the esp and flored it and it started making weard whistling sounds and it gets in emergency mode or limp mode after been throttled for a couple of seconds in the turbo area. I have driven her to the service and there were no damage from the turbo ways. I was wondering if throttle body could be the problem ?
I'm not familiar with this model. Have you checked for Diagnostic Trouble Codes (DTCs)?
Check for vacuum leaks
Yeah, I think found the problem. There is a gap between my turbo and the aluminium pipe that goes to the intercooler. I will get that fix on Wednesday and hopefully, it will fix my problem.
is it possible to use the scan tool if it has PIDs to view the throttle body readings rather than a scope or would you still connect a scope?
You may be able to command the throttle plate open and closed to verify motor operation. You can also graph the throttle position sensor PIDs but the refresh rate is too slow to catch a glitch.
@@MotorAgeMagazine thanks
Does the car relearn After several drive cycles
My 1996 1.6L Toyota camry throttle body had siezed. I pulled it out. Inspected it, tried to wiggle the plate open. It wouldn't budge. I called a friend over and he gave it a tap with a hammer and it worked!!!!!! Mind you my engine bay is spotless clean and the throttle body was in good shape no dirt inside. DONT BE AFRAID TO TAP IT WITH A HAMMER FIRST hahaha
Very informative 👏 thanks.
What if idle is really low at stop lights but good after about 30 minutes of driving . my car shakes and sometimes I get bad fuel economy along with horrible takeoff. What is the issue ? Did the relearn the sensors cleaned ,the throttle cleaned and fuel injectors changed . still getting low rpm. G37 sedan 2019
Did you perform the relearn with the engine cold or at operating temperature? Check the procedure and make sure which is specified for your vehicle.
Love this..... is there a list of all tools I will need before I start so I have them ready and in one place so I'm not surprised ?
The first tool you'll need is a source of service information specific to your vehicle. Make sure to read over the procedure before you even open the hood. Actual tooling will be dependent on the make and model but basic hand tools are usually all you need. Be sure you understand the relearn procedure for your car!

Additionally, I can arrest the "hiccup" by throttling up to 2000 rpm or more thus forcing a kickdown. I just had the transmission rebuilt at considerable cost and it continues to "hiccup". The local trans shop sees no transmission codes. The roughness can't be good on the transfer case chain and other components.
Great video! I took my throttle body off,because my 2013 Charger has the red lighting bolt on dashboard.Something is rattling around in the throttle body.Doesn’t seem normal?
Likely not. :-)
I have a 2016 Jeep Cherokee 3.2l Trailhawk. I’ve replaced the throttle body, the mass air flow temp sensor and the accelerator pedal with sensor. After each replacement of each part, the red lightening bolt indicator would return. Some drives it wouldn’t happen, but most times I take it out, it pops back up on my dash board. Is there something that I’m missing as to why this keeps happening?
the lightning bolt is a warning for electronic throttle control problems and be related to a lot of stuff. Is your fuel pump (in tank) operating correctly. check fuel pressure.
Hello, i Have problem on my car nissan elgrand e52,before this i have service and clean the throttle body,now the issue while driving have wrning and the car automatic no power and cannot accelerate
Excellent detail explanation. Great video
I have a question?
I have a 2006 G35 sedan and so far I changed the catalytic converters,A/T FR/B solenoid,Transmission Temperature sensor, fresh transmission fluid and filter, MAF , APPS, new battery, and new brake pads, plus fresh oil change and filter. My car symptoms are slip & vdc lights are on at the same time as the check engine light, late gear shifts, hesitant to accelerate from complete stop, RPMs are hesitant when pedal is fully depressed (very sluggish rev ups), reduced power, delayed response when stepping on gas pedal. Ive done the idle relearn procedure many times but its not sticking. Im lost , HELP!
Sorry for the late reply. Let's start with the Check Engine light - what codes are stored?
I replaced the MAF Sensor and the engine line went out, but it still wont go faster than 35-40 mph, im thinking this seems 'easy' enough so i'll try removing it and possibly replacing it.
You probably have an vacuum leak or a clogged catalytic converter.
Did you ever find out the solution?
We took our 2016 Dodge Journey crossroad to a garage and had it replaced. It was still doing the same thing. The throttle body light came on. The garage replaced it again incase the 1st was defected. After $1000 dollars nothing has changed we are still going through the same problem. What could be going on?
Is that the only complaint? That the light is on? Or is there another concern that started it all? Any DTCs that you know of?
Why does the gas peddle get stuck at the bottom and I can't get full throttle unless I'm on cruise control and I increase the speed that way?
Check the operation of the Accelerator Position Pedal assembly
Would that be a reason for the car not even start?
That’s what I’ve been trying to get an answer to for the last couple of hours.
Lexus Rx 450hy cruise control not working?
Hello, Pete. If you have a higher voltage in one of the APP sensors as you sweep the throttle( from normal to higher than specs), how could that affect the TPS sensors? Your answer will be highly appreciated.
The ECM moves the throttle in response to the APP inputs. If the input is wrong the throttle position may be off. .
@@MotorAgeMagazine Thank you, Sir.
@@MotorAgeMagazine what if the plate is opening fine but no revs 🤔
@@mattlawton4715 Interesting question. If more air is entering the engine, RPMs should rise. Is the air entering the engine?? Is the ECM seeing the throttle opening and adding additional fuel?? I would want to see some scan data for this one...
@@MotorAgeMagazine yes like if the injectors stayed at idle but the throttle plate was opening so getting moor air but fuel not increasing 🤔.
My tb on my diesel nazda 3 1.6 stays open when motor is off. Its that normal? Shoud it be closed? No check engine lights apeared.
For Diesels that's normal.
Thank you for your information
10-10 vid ima try on my Chrysler see if I can fix anything
Thanks for the video, i have a 1 series 116i benzin 2007 manual bmw, with loss of power and hesitations, when ascending gears, from 1 to 2nd and so, on descending gears, no problem at all, no fault codes at all, changed throttle pedal and sensor, spark plugs, no result. Can you please give me a direction where to.look
Is the Check Engine light on? Have you checked for trouble codes?
@@MotorAgeMagazine thank you for reply, nothing, no single code, except the ac fan, all components without any code, no missfire,
@@mycomment6699 Forgot to ask - is this a gasoline or diesel vehicle?
@@MotorAgeMagazine it is Gazoline
@@mycomment6699 There are a number of reasons a gasoline engine can develop low power issues. Restricted exhaust, cam timing, low compression, turbo malfunction - the list goes on. You may want to enlist the aid of a qualified technician to help you isolate the fault(s). It will likely require diagnostic equipment you may not have - factory level scan tool and diagnostic oscilloscope would be on my list.
Okay I need Help no one has answered this I have changed the tps sensor like 7 times bc when I get into the the throttle my throttle body door closes but my car is also turbocharged
So let me understand this - are you saying that when you step on the pedal, the throttle plate moves in the opposite direction - closing instead of opening? Or do you mean that you're experiencing low power? On a turbocharged engine, it is critical that the air tract from the turbo to the intake is completely sealed - and leaks will lower boost pressure and power.
I wish this man was my mechanic!!😭😩
Great job done..
I have Europe Toyota hilux diesel engine 2017

I have a Nissan maxima 2018, the car shifts and drives then if I slow down and stop. I’ll pump the gas and it won’t rev or have any power but all electric and the car is rolling.

Hope you can help, 2012 silverado 6.0L trying to do a throttle sweep test, but i keep getting engine speed detected while engine is off!
How are you trying to perform this test and why?
@@MotorAgeMagazine with a scan tool.
I noticed the rpm will be correct while engine is running then within 10 seconds rpm goes to 9742 and stays there.
So im trying to do throttle sweep test on my scanner but i keep getting engine speed detected while engine is off!
@@moecapitolnetwork2916 Have you tried a different scan tool? What kind is yours? Also, are you trying to graph the TPS data? That won't catch a glitch - the refresh rate on a scan tool is too low.
@@MotorAgeMagazine thank you very the tips very helpful, i will try that.
2006 mini S ....throttle body not opening when car on acc 😪
Hi there Pete I'm currently having this problem with OBD P061C code any input will help
2013 5.0 mustang
This code is set with the calculated engine rpm is no in line with the desired (programmed) rpm for a specified time. On your Ford, it can be caused by a problem with the Crankshaft Position Sensor signal to the PCM, or the Camshaft Position Sensor signals (two, I believe) to the PCM, or a problem with the PCM itself. But before you replace the PCM, make sure that the signals are strong, it has good power and grounds, and the connector pins are not damaged or corroded.
I would use a scope at the PCM connector to monitor the CKP and CMP signals, looking for any fallouts or inconsistencies. If that's ok, I'd check power and grounds to the PCM next. Good luck!
Where can I get does motor to replace mine
They typically come as an assembly.
Hi sir, i have a 2006 lexus rx330 awd, that i will need to replace the Throttle body. I ram across two hoses. One on the right is coolant. The left hose i have not unplug it.. do you know what is that connected too and soni need to bleed those two lines afyer replcaing the tb? Thank ypu sir.
They are both coolant lines and you can pinch them off as I did here. If you do that, you shouldn't lose enough coolant to worry about.
@@MotorAgeMagazine ok thank you.. will do that.. have a good day sir..
