Can I adjust the voltage that is required to activate the TPS open/closed circuit on idle?

@ .5V the TPS closed switch was on, turning off @ .55v. Now it turns off @ .4v.

Any ideas?

Ok, does the ECU learn the closed position after a certain number of start-ups? Why should moving the TPS alter the idle close voltage?

Standard ecu? I think it allows a certain range for idle and full throttle so it's below .5v if you have moved the tps full throttle voltage will be lower also it could be a worn sensor issue as well I have no idea what the ecu does with it I know my link you have to set the open and closed throttle positions
