Re: PROBLEM: Reduced Engine Power and Service Active Handling
If water did get into TPS since it is a resistor pot and could get burned spots which will cause weird problems as the PCM relies on TPS to crosscheck TPS angle to APP/TAC ( drive by wire) and MAF output.
If they do not agree the PCM can trip into limp or open loop modes.
A scanner could be used and even with just key on step on gas pedal and what TPS angle and see if there is any dead spots or
With a ohm meter connect to ground and one of the TPS output and hand turn the butterfly.
One TPS pot output starts at zero and goes up in resistance while the other pot side goes high to low.
