TPS or Throttle Position Sensor Adjustment 1

[kokotovina]

I appreciate the effort, but would it be a bit problem to use a human voice??

@kokotovina Hi, we're always open to improve the user experience, but would hate to set our videos as rental. We believe that this information is needed and that these videos should be FREE for everyone. So, to that effect we try to make the development process as smooth as possible. With over 5 million views since we opened, our viewer response is overwhelmingly positive. We hope to see you here today and in the future. All we ask is that folks participate. Thanks.

@ADPTraining do you get me? All I'm about is a human voice, which would make this video being much better...

[ADPTraining]

@kokotovina I do get you and you're right. In fact we have 98% of folks praising our video and 2% with dislikes. But, it is that 2% that I care about, because it keeps us on edge and make us better. So, thank you so much for your input. Rest to sure that we'll take it into consideration. You may want to do s search for our latest series "Stories from the Road" and "Advanced Electronics" and let us what you think. They both here in this channel. Keep it and thank you.

hi i've got a question...on my 96 grand am 2.4L it jerks a little bit when i slowly accelerate and it sometimes wants to cut off on me, could it be my TPS sensor??....i've recently had a tune up and i changed my o2sensor , and i had the throttle body cleaned and it still jerks, it makes slowly accelerating a pain, at times i have to drive rough just to avoid the problem, but could it be my TPS sensor?? 

[ADPTraining]

@Bigroberto2008 OK, first things first: Does the engine hesitates during light acceleration or hard throttle? Is it a quick jerking response? If you stay in first gear and slowly accelerate, does it still jerk? Do those things and post back with more.....

[Bigroberto2008]

@ADPTraining it hesitates during light acceleration and yes it is a quick jerking response....and when in first gear from a stop light or a red light and slowly accelerate it still jerks then takes off (at normal speed)...my CNL also comes on as well at times, and its on and off and the code reads P0172 Bank 1....but i think its the TPS sensor thats causing that to happen....idk....cuz i've had everything else checked and its fine.

[ADPTraining]

@Bigroberto2008 Forget the TPS sensor. Your observation about CEL blinking is a dead giveaway and this only happens during a severe ignition MISFIRE problem. You have a cassette DIS ignition system. These systems are notorious for ignition arching at the covered cassette enclosure. Also check the ignition boots/tips for carbon tracking. Your issue is ignition otherwise you'd never see the blinking CEL (check engine light).

@ADPTraining Post back with more whenever you can... Keep posting...Thanks...

[Bigroberto2008]

@ADPTraining ok i will get the ignition coil checked out but my CNL does not blink sorry lemmie rephrase that....it comes on for about a day then its off for a day...so its on and off on diffrent days but it is not blinking....but i will get that checked out and i will get back to u...thanks for ur help!

@ADPTraining nice videos, can you give me an advice?

Sometimes when at idle, engine seems to increase rpm by around a steady value of around +1000 rpm for a few seconds then it goes back without touching the pedal.

Do you know what I should check ? Car is 2001 VW Golf 4 1.6 16V.

Thanks.

[ADPTraining]

@adrianTNT Watch the scan tool for changes at the relevant PIDs. If you have an illegal LOAD on the engine you would see exactly that, a momentary raise and fall of idle RPM.

[adrianTNT]

@ADPTraining you meant to check with tools like Vag-Com? (That is what I have). But I should have mentioned that this happens very rarely, just once at two months or so, not often, if I should check with scan-tool in exact same moment it would not be possible.

The "PIDs" are the number values and adjustments in Vag-Com program?

Since these anomalies are so rare they are not a problem but I was just thinking they might be sings of some other problems.

Thanks.

[ADPTraining]

@adrianTNT The Vag-Com is nice, but probably overkill for this issue. Try a regular OBD-2 scan tool. There are tools out there that record selected PIDs on command from a designated button for intermittent issues like that, which are hard to diagnose. Good luck.

very useful.
