Diagnostic Fault Information
Typical Scan Tool Information
Circuit/System Description
The clutch pedal position (CPP) is a three wire sensor, connected to a 5-volt reference circuit, a low reference circuit, and a signal circuit. The
engine control module (ECM) supplies 5 volts to the CPP sensor, and also provides a sensor ground path on the low reference circuit. The CPP
sensor sends a voltage signal to the ECM on the signal circuit. The voltage on the signal circuit will vary from a voltage less than or equal to 5 volts
when the clutch pedal is released to a voltage less than or equal to 1.5 volts when the clutch pedal is applied.
Conditions for Running the DTC
* DTCs P0641 or P0651 are not set.
* The system voltage is more than 9 volts.
* The ignition is in the RUN position.
