resetting tps

im not sure what you call this. but i read somewhere in a thread i think called tips and tricks about reseting tps. you have just the ignition on only and wait for most of the lights to go out then push throttle slowly to wot then let all the way off. i did this and swear the car runs and shifts better. anyone else tried this?

Is this what your talking about?
ETC Throttle Calibration/Characterization:

Late LX/LC Model (5.7LTR HEMI) Charger/Challenger Throttlecalibrationprocedure. It basically does a zero/span characterization
for PCM on fly-by-wire throttle system. This procedure if followed correctly will hold until battery power is cycled again.

PCM Zero/SpanThrottleCalibration

Throttlecalibration can substantially improve throttle responsiveness over "factory standard." Many people notice what appears
to be sluggish throttle response or a "dead area" at initial accelerator depression.

Throttlecalibration can take care of these.

Procedure steps:

1) Insert ignition key and turn to "ON" (not start).
2) Wait for all idiot lights to go out. Check Engine Light may remain on.
3) Slowly depress the accelerator pedal all the way to the floor.

(HOLD to the floor for about a three second count.)
(On some PCM versions, Engine Check light may start flashing here)
4) Slowly release the accelerator pedal until it's all the way back up.
5) Turn the ignition key to "OFF".
6) Start the engine.

Most drivers notice an immediate change in throttle response, but depending on your driving style, you may need to repeat this

procedure periodically due to the computer's adaptive programming.

NOTE:
You will likely need to repeat this procedure any time the battery is disconnected.

Well thanks for giving it to him. It's great info and It's alot easier to go to the site and click on tip # and it go there than looking thru 100 sheets of paper.

I doubt that does anything.The chrysler scan tool has an ETC (electronic throttle control)relearn procedure.The scan tool puts the pcm in throttle relearn mode and syncs the throttle sensor(on gas pedal) with the ETC.I doubt it is in learn mode at every key on!

The scan tool, predator, and TPS key trick can all recalibrate the TPS/APPS.

I put a new pcm in a car today and the throttle would not work.Had to do the learn procedure with the scan tool, to get it to work.Stepping on the pedal slowly once or 10 times didn't work!Why would they have learn procedure at every key on,someone could accidently press halfway on the pedal.I can see the lawsuits coming!
