Relearn for tps? - Page 3

350rs · 08-29-2010, 08:37 PM

Checked wiring. Its all 100%. It does have some kind of aftermarket weatherpacks though. I pulled the rubber on the pack itself, and its clean and corrosion free. So it should be fine. Gave it the ol pull test. and its holding tight. So im thinking, more so hoping, that the sensor was just " worn out " from not knowing that relearn procedure talked about earlier in the post. I did about 2 dozen starts. Not a single one of them went to a high idle. Went on a few drives and tried to duplicate what would normally cause it to be high, and its fine.

I hope this fixes this problem once and for all.

Great thread guys. I just did the re learn and the idle is normal again.

Another vote for making this a sticky.

i agree.

hey does anyone know what the voltage should be for throttle closed vs WOT vs engine idle? Im trying to pinpoint a problem that may be related to my TPS. With the car off and throttle closed its reading .5v and 4.5v at WOT. When the car is running and the throttle is closed the voltage drops around .15v. is that normal or should the voltage be the same car running vs car off?

Per GM Service Manual - The TP Sensor reads between 0.36-0.96 volts at idle to above 4.0 volts at Wide Open Throttle.

It looks like you're sensor is working properly, clean connectors would be the only other issue here. Recalibrating is always a good idea anyhow...

I would think the voltage reading from the sensor should stay the same with the engine running or not... but I can't say that is for certain. I've never tried measuring it myself to see if that is normal or not. I know voltages to some accessories can change depending on if they are drawing from the battery or the alternator.

So the manual does say it should be around .5v idling... cuz im getting only +.1v when the car is on and idling so i wondering if it is my TPS then.
Does anyone want to test theirs out and verify??
I ordered a new data logger since mine crapped out, hopefully this next week i can at least scan what % the PCM thinks its at.
