Symptoms of a Bad Accelerator Pedal Position Sensor (Learn how it works and why it fails)

Thank you!

Can it be bad and not throw a check engine light?

This guy is the best. Reminds me of cy.

My 2015 chrysler 300 3.6 doesn't want to turn over, I have P0123 and P0222, I put a new throttle body but nothing. I used a scanner and appD is at 8.2 and appE is at 3.9. When I step on it both D sits at 91.4 and E at 45.5. Can anybody help!!!!

great vids brother, your very smart with vehicles.

Thank you sir. I hope this is my last problem with this Audi. If it isn't, I'm giving the car the ol' Yeller treatment.

Great explanation 👌

Thank u

Hi i have got the a class mercedes a180 2014 w176 petrol acceleration pedal i.m till end fast but the RPM needle moving slow on 4000 RPM. NOT on 5000 RPM please can you tell me whats the problem please thanks?? And the same time very slow accelerating

Unlike other comments, my concern is the opposite. 2009 Matrix/Corolla the pedal is very sensitive from a stop. A slight depression of the pedal causes motor to react like I pressed halfway. You have to be very carful not to have "jack rabbit starts". APP sensor?

What would cause my truck to have an irratic pedal issue? When accelerating, if i floor it, the truck will act like im at half throttle, ill feather it back just a tad, and it will get all its torque back. Basically most of the time i have to find the sweet spot just to have all my horsepower there. I KNOW its somewhere between the pedal and the throttle body. No codes though. Is there a way to calibrate the sensor? Ive tried the usual "key on engine off, slowly push pedal to the floor, hold 10 seconds, slowly let off, key off", and tried the same thing without the slow press and depress. Would a worn contact point at the floored position give the throttle body a wrong voltage reading, causing it to think im only at half throttle? Having no code is where i get annoyed lol

Thanks 👍🏼

I have a 03 Silverado 1500HD would the APP sensor cause the engine to stay running when ya disconnect the MAS air flow connector?? I just put a new mass airflow sensor on my truck and it’s still doing the same thing to wear when I disconnect the wire to the mass airflow sensor the engine stays running?

2010 Nissan altima 2.5 engine. Changed timing chain, new air filter, all 4 coil pks, all new spark plugs. It helped my car gain more speed, but still, when i go up a long hill, i have the gas pedal all way to the floor board and i have to use the automatic shifter because if i let it go over 3100 rpm, it goes into limp mode. Nobody can tell me whats wrong with it. Im lost ! Can you please provide any information that might help me know what is going on. It dont cut off when this happens, but throws codes up like slip, and o God, alot of codes, i pull over on sude of road, cut the car off, then i start it back up and all codes are cleared out. And has no check engine light on, ( tire sensor light has been on since i bought the car. But please, can you give me any reasons my car is acting like this.. Thank you, Sir 😢

great video

Can APP sensor cause truck to not start?

My cruze runs smoothly up to 20 mph. Over 20-30 it bucks slightly like bad fuel or lack of fuel. Does tthis seem like a bad APP sensor? I'm getting no codes.

If i floor my rav4 it doesn't accelerate for nothing... but as soon as i start letting off of it at a certain point it starts speeding up. very jerky as well, i used the odb2 dealio and it said the car was at %17 throttle not pressing it at all... idk if that's normal but i pushed it all the way down and pretty sure it was at about %60. ordering one now, i thought it was the entire pedal as well? i guess not based on this video

Would this cause my car to crank but not start issue

But you failed to inform that it causes throttle body not to open n closes

Another possible Fault to add into my 97 VectraB :)

Does close loop affected by PPS? Close loop jump into open loop if I keep out my feet of gas pedal while drive at 50 MPH or more. Close loop again until I press gas pedal or let itself reduce speed around 30 mph or less. Any clue?

You are the best lecture, did get the info I needed. Thanks

I have a 2004 Chevy Colorado with a reduced power warning on the gauge system window. The code is P2120 throttle pedal/ position sensor/ circuit switch D. Would this fix the code it's throwing out? Thank you for your time and advice. I really don't want to take it to the shop, if it can be fixed at home. It's gone numerous times to the shop already, although it's never had issues in it's younger days. Now that it's older with 200,000 plus miles I love this trucks, the sound of it's engine. Recently replaced the transmission lines and an oil pressure sensor done by the repair shop. Now it has this code and before the code came up, while driving it, it would feel kinda rough shifting as I drove it. Thank you for any advice you can share.

My 2017 malibu takes around 5 seconds to respond after pressing pedal 🥴 will replace tomorrow hopefully fixes issues!

thank you. Saved me a bunch of money

my 2010 suburban has a +10 from tps and app, is this normal. i also did a relearn throttle, but still has this issues

You’re welcome in my life after this help

This is exactly what my Nissan Quest van is doing. I’ve spent a fortune on it and still have problems

Can cause that no response gas pedal almost all time i Press fast gas pedal ??? Bcz my car mk4 golf doesnt response and rpm goes itself 10++and stays minimo

09 Nissan Murano,, im having the symptoms randomly , but no check engine light or codes. Is this possible ,have not replaced the APP yet .

Great Video! Very informative and answered every question I had

I'm having this problem with my Buick Rainier. I will check on changing the whole accelerator.

My car's problems,
1. Reduced power upto 60kmph
2. Lots of hesitation jerks
3.TPS always on 4-5% even if pedal is pressed all the way.
4. Noticable latency in pedal pressing and engine response.
NO CHECK ENGINE LIGHT

Hi will this also cause car to while driving stay at a certain speed without pressing gas pedal??Have this happened today I let go off gas pedal and car kept going.

Very Informative and thank you 👍

On GM vehicles, a "Reduced Engine Power" or "Engine Power is Reduced" warning on the information panel of your gauges will pop-up. On early 2000s GM vehicles, a lot of time it was in the wiring going into the TPS. It's an orange (I believe because have colorblindness) wire that breaks.

Would you be able on a Deisel motor that the pedal has cable that move the top of the injector pump, would that tell you if it's the pedal sensors. Right now I can't throttle the motor up with the pedal or where the pedal cable moves the injector pump throttle position, so no rev with pedal and no rev at the motor where the cable is hooked up. I guess my question is if the pedal doesn't work should it work at the cable point on the injector when you move it by hand, thank you for your time, iv got a old 1993 nissan ud 1300 turbo series dump truck with the tb42t diesel motor

How can you tell if it's the tps that is bad or the app sensor. How do I know which? 🤔

Sir you had me subscribed within a few words!!😮

I have problems with my 2006 Nissan Murano, Changed Pedal, Changed Trottle body and still car won't accelerate. Once changed car gets heated it goes to limp mode with Slip light and VDC displaying a check engine light, please any suggestions for possible solutions?

Hi sir my truck is 18 weller frhatliner cascadia there is no disel when I need too push it in my foot no disel power only when torn off the engine couple of times and then the check engine light off and drive normal when I park over night the next day same problem and do same what I did before that's day is that's the same problem what you talk about and thank you

I have yr 2000 Mercedes E55 and it seems like it doesn't want to go faster than 55 mph, my cheap scanner says pedal sensor code P1542, im gonna take it to a Mercedes shop because i will just make things worse.

Gained a subscriber. Well explained.

i need to press my car pedal like 3 percent if not i will jerk or i need to wait 1 second after realising pedal before hit pedal

The audio went out right when i needed to hear about limp mode

Thank you. Great information! My Accord is experiencing this very problem. I will replace the APPS on my car tomorrow.

My semi auto van is not selecting gear if I change the throttle position sensor which comes up as my diagnostics will that fix the problem or do I need a new APP also or is it the same part is what I’m getting at thank you

How can you tell if it's the tps that is bad or the app sensor. P0120 code says it's one of them. How do I know which?

I'm like your Video
