Circuit Description

Throttle Position (TP) sensor measures amount of throttle opening. PCM uses TP sensor information for fuel delivery calculations. TP sensor readings during wide open throttle are greater than 4 volts, and less than one volt at idle.

Conditions required to set DTC are:

• Ignition is on.
• TP sensor signal voltage is more than 4.78 volts for a period of .78 seconds over a 1.5 second period.
