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 4 Volts, (at Wide Open Throttle). SEE 
SPECIFICATIONS.
