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 4 volts and one volt at idle.

Conditions required to set DTC are:

• Engine running and throttle steady at less than one percent.
• No P0106, P0107, P0108, P0122 or P0123 DTCs are set
• MAP reading below 55 kPa.
• Predicted TP ANGLE not close to actual TP ANGLE.
• Above conditions present for 12.5 seconds over a 25-second period.
