Throttle Position (TP) Sensor

Throttle Position (TP) sensor is located on side of throttle body. TP sensor delivers an input signal indicating throttle valve opening angle to Engine Control Module (ECM). Voltage signal to ECM increases as throttle opening increases. With throttle fully closed, ECM should receive a voltage signal of about .7 volt. With throttle wide open, voltage signal should be about 2.7-5.2 volts. ECM uses this input signal for adjusting air/fuel mixture, power increase correction and fuel cut-off operation.
