Throttle Position Sensor: Description and Operation

Location

Sensor mounted on throttle shaft.

Purpose

PCM uses sensor input with other inputs to determine current operating conditions. 

PCM adjusts air/fuel mixture (injector pulse width) and ignition timing.

Operation

PCM supplies 5 volt sensor reference voltage.

Sensor is a variable resistor (potentiometer), whose resistance is dependent on the angle of the throttle blade (or throttle opening).

Output voltage ranges from approximately 0.5 Volts, (at idle position), to approximately 3.5 Volts, (at Wide Open Throttle).
