Most of the newer car equipped with TPS, are not adjustable per say, however, when you do replace a TPS, you need to check the TPS for proper voltage. They can move slightly on the mounting screws. A slight movement can vary voltage!
The TPS is simply a potentiometer used to vary voltage. The best way to check the voltage is with a scanner, but if you do not have access to one, you can use a DVM. The TPS
WHITE wire, is the PCM reference signal and should measure 5.0V with ignition on. (Engine does not need to be running) The
BLUE wire will show variable voltage from a closed TB position, usually .45V, up to WOT, where it should measure between 4.0V to 4.5V max. The
BLACK wire is ground.
