Signs & Symptoms of a Bad Throttle Position Sensor (TPS)!

Рет қаралды 64,208

Are you experiencing erratic engine performance or getting P0120-P0124 engine codes? It could be a sign of a faulty Throttle Position Sensor (TPS). In today’s video, Jake explores the intricacies of the TPS, exploring its function, common symptoms of failure, diagnostic procedures, and effective fixes to restore optimal engine performance. The Throttle Position Sensor (TPS) is a vital component of the engine management system, responsible for monitoring the position of the throttle valve. By providing feedback to the Engine Control Unit (ECU), the TPS ensures precise control over the throttle opening, enabling smooth acceleration and engine operation.

Thank you for sharing the video. It was very insightful to troubleshooting my car issue. I will try the tips you suggested. I changed out the TPS, cleaned the MAF sensor, but the problem didn't go away. I will try to clean the throttle body next.

I have a 2014 Kia Soul+ 2.0. It has every single symptom described here except the stalling and CEL. It jerks when accelerating between 35-45 mph. It won't accelerate past 60. Starting around 40-45, it doesn't want to shift unless i let up on the accelerator. It idles rough. At this point, I've changed: plugs, coils, pcv valve, MAF sensor, upstream o2 sensor., oil & filter, have run a fuel system cleaner through on 3 consecutive fill ups. Even switched to exclusively use Top Tier member fuel. Is it possible for the TPS to fail without initiating a code/ illuminating CEL?

94 Lexus ES300 V6, engine stalls 50 180 seconds after car starts(maybe coolant sensor? as car heats up?),, but i will look at throttle and idle areas to see if grimed up, only 47K miles, at stop light i have to put it into low gear(automatic tx) as first gear slips in Drive, the only code i have is the Shift solenoid "A" electrical code. I have been getting by since august 2023 shortly after i bought it so i am hoping the issue is fuel,air, spark, sensors and not tranny, what do u think? Wish u were near greensboro nc, i like your slow logic based explanations!

Really great video thank you! Q: Is there a case where a car has no any accelaration pedal sensor on gas pedal? I have an i30 Hyundai 2008 1,4 and i can not find this out.

@8020Media 2 ай бұрын

Certainly, from a quick search it seems like the I30 uses a cable-operated throttle control system so it wouldn't have an accelerator pedal position sensor.

@@8020Media Thank you very much! Really appreciate ☺ So do you believe that there is a way where i could make the gas pedal more sensitive as it's a little bit lazy right now. Don't know if throttle sensor could change the overall exprerience.

2017 Ford transit, I had a bad throttle body with code which I replaced and reprogrammed by driving the van for 20 minutes to learn my driving, 6 months later now when I deaccelerate and using the brakes to stop when speedometer reaches about 30 mph before stopping the rpm shoots to 4000 rpm then it comes down, no codes at all and it does not happens everytime just randomly, I don't have any jerking or any accelerating problem at all , any thoughts appreciated thx

Is it possible to get no error codes when this issue occur. I have same symptoms with my car, but diagnostics does not show anything at all and there is no warnings on dashboard. I was driving the car, at one point I have put my foot off the gas paddle to slow down and then put my foot on the gas paddle again, just a little bit and noticed it does not accelerate like it works on 2 or 3 cylinders or like its stuck in higher gear. But it did not. When I stopped on red light it barely moves and. It also rough idles. We have already checked injectors and camshaft, everything works perfect. For Injector we basically replaced the ones we suspected to be bad. I have 1.6 hdi Peugeot 508 88kw 2017

Have you tried replace the pcv valve? Also clean throttle or replace idle air control Valve? Also try clean injectors.

@kevinbagwell4834 2 ай бұрын

I'm going to assume you have at least 150,000 miles on the vehicle seeing how old it is, so, if you've never replaced the TPS or MAP, I'd start there, it's about time for either or both of those to fail and you'll likely be replacing them soon anyways. O2 sensors will probably soon follow. Hope this helps.

My Nissan Nerva 2000, started dropping its idle slowly over a cupule of days to a point where i had turn up the idle screw back up to 700 RPM, when the car is warmed up after driving for about 20 minuet's it would give a bit of a misfire while siting at a red light but then come good on acceleration, it only happens when the car is warmed right up..? No vacuum leaks, Throttle body is clean, Could it be the idle air control valve..? Or a faulty TPS..? My car has a 14 pin port, I've been to three mechanics for a diagnostics test and they don't have the right scan tool for my year model, And it never fails when a mechanic takes the car for a test drive, Well the bloody thing doesn't miss a beat. I guess I will have to try changing both.. Also no engine check light comes up on the dashboard..

Hi I have the jerky and hesitant acceleration with also not reving all the way, but can it also cause RPM to get stuck? When that happens I flip gas pedal and it gets unstuck.

Check your throttle body to start, it could be sticking or something like that - especially if your car doesn't have electronic throttle control.

My 05 lexus rx330. Driving on the hwy @ 45mph, I stepped on the gas pedal to quickly accelerate too pass another car. The car jerked & the engine, vsr, track off light all came on. The gas pedal felt dead, the car was slowing down, could not accelerate. I had to pulled over & stop, turned off the car. I waited a few minutes started up & drove back on the hwy. My car came back to drive normal but the engine lights were still on. I drove home. Obd code P2112???? It said throttle body stuck. So is it the throttle body sensor or gas pedal sensor or both?

Let me tell you that tps sensor is a very very shitty sneaky sensor, what can cause your car to run rough, sluggish, poor ! without throwing any fault codes ! my advice: if you replaced most sensor and the car is still running like crapp and consumes more fuel than usual, just replace this shitty sensor without any hesitation ! it makes your car new and alive again ! Just be sure you buy the Oem sensor, otherwise you make it a lot worse !
