Circuit Description
Throttle Position (TP) sensor measures amount of throttle plate opening. PCM uses TP sensor information for fuel delivery calculations. TP sensor reading during Wide Open Throttle (WOT) is about 4.75 volts and 0.25 volts at closed throttle.
Conditions required to set DTC are
- Ignition switch in ON position.
- TP sensor signal voltage is less than 0.22 volts.
Diagnostic Aids
Check for and repair the following condition(s): Check for faulty connections or damaged harness. Ensure harness is not routed too close to high voltage wires, such as spark plug cables. If connections and harness appear okay, observe ECT display on scan tool while moving all related harnesses and connectors. A change in scan tool display may indicate fault location. Check for skewed MAP signal or faulty MAP sensor by comparing scan tool values of a known-good similar vehicle.
