Technician a says that the 3 wires on the tp sensor include a 5-volt reference voltage from pcm, plus the signal wire to pcm, and a ground wire to the engine block. technician b says that the tp sensor is used by the pcm to determine torque converter engagement and transmission shift points. who is right?

Technician B

Explanation:

It is a known fact that the Throttle Position (TP) sensor, is used by the PCM to determine torque converter engagement and transmission shift points. The TP is a 3 wire potentiometer, often used for vehicle fuel-management systems which includes a voltage of +5V applied to the PCM, not the resistive layer.
