Throttle Position (TP) Sensor, Potentiometer 2 (V)

Measurement range: 0-80 V.

The engine control module (ECM) derives the value from potentiometer 2 for the throttle position (TP) sensor.

The value must decrease with an increased throttle angle.

Approximately 4.0 V = throttle closed.

Approximately 0.5 V = wide open throttle (WOT).
