Technician A says that the TP sensor signal voltage should be about 0.5 volt at idle and increase to about 2.5 volts at wide-open throttle (WOT). Technician B says A TP sensor can be tested using a DMM, DSO, or scan tool. Who is right?

Question

Quizplus · Accepted Answer

Technician B is correct because a TP (Throttle Position) sensor can indeed be tested using a Digital Multimeter (DMM), Digital Storage Oscilloscope (DSO), or a scan tool. Technician A is incorrect because the TP sensor voltage typically ranges from about 0.5 volts at idle to about 4.5 volts at wide-open throttle, not 2.5 volts.
