Circuit Description

Throttle Position (TP) sensor measures amount of throttle opening. PCM uses TP sensor information for fuel delivery calculations. TP sensor readings during acceleration are much higher than those during deceleration or idle. DTC will set if PCM detects an out of range condition.

For duplication of DTC, ensure no MAP or TP sensor DTCs are set, engine is running, ECT sensor temperature is greater than 158°F (70°C), MAP sensor reading is less than 50 kPa or greater than 70 kPa, and MAP is steady for 5 seconds or more.
