DTC Descriptor
DTC P0807
- Clutch Pedal Position (CPP) Sensor Circuit Low Voltage
DTC P0808
- Clutch Pedal Position (CPP) Sensor Circuit High Voltage
Diagnostic Fault Information
Circuit/System Description
The clutch pedal position (CPP) sensor is an input to the engine control module (ECM). The CPP will be more than 4 volts when the clutch pedal is released and less then 1 volt when the clutch pedal is applied. The CPP is a potentiometer type sensor with the following circuits:
* A 5-volt reference circuit
* A low reference circuit
* A signal circuit
Conditions for Running the DTC
P0807 and P0808
* DTCs P0641 or P0651 are not set.
* The system voltage is more than 9 volts.
* The ignition is in the RUN position.
Conditions for Setting the DTC
P0807
The CPP sensor voltage is less than 0.25 volts for more than 1 second.
P0808
The CPP sensor voltage is more than 4.75 volts for more than 1 second.
Action Taken When the DTC Sets
P0807 and P0808 are Type A DTCs.
Conditions for Clearing the MIL/DTC
P0807 and P0808 are Type A DTCs.

Circuit/System Verification
1. If DTC P0641 or P0651 is set, refer to Diagnostic Trouble Code (DTC) List - Vehicle (Diagnostic Trouble Code Descriptions) .
2. Ignition ON, observe the scan tool CPP sensor voltage parameter. The reading should be between 4.75-0.35 volts and change as the clutch pedal is applied and released.
3. Clear the DTCs with the scan tool. Operate the vehicle within the Conditions for Running the DTC, or within the conditions that you observed from the Freeze Frame/Failure Records.
Circuit/System Testing
1. Ignition OFF, disconnect the harness connector of the CPP sensor.
2. Ignition OFF, test for less than 5 ohms between the low reference circuit terminal A and ground.
• If greater than the specified value, test the low reference circuit for an open/high resistance. If the circuit/connections test normal, replace the ECM.
3. Ignition ON, test for 4.8-5.2 volts between the 5-volt reference circuit terminal C and ground.
• If less than the specified range, test the 5-volt reference circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the ECM.
• If greater than the specified range, test the 5-volt reference circuit for a short to voltage. If the circuit tests normal, replace the ECM.
4. Ignition ON, verify that the scan tool CPP sensor parameter is less than 0.1 volts.
• If greater than the specified range, test the signal circuit for a short to voltage. If the circuit/connections test normal, replace the ECM.
Important: The 5-volt reference circuits are internally and externally connected at the ECM. Other component DTCs may be set. If other DTCs are set, review the electrical schematic and diagnose the applicable circuits and components.
5. Install a 3-amp fused jumper wire between the signal circuit terminal B and the 5-volt reference circuit terminal C. Verify that the scan tool CPP sensor parameter is greater than 5 volts.
• If less than the specified value, test the signal circuit for a short to ground or an open/high resistance. If the circuit/connections test normal, replace the ECM.
6. If all circuits/connections test normal, test or replace the CPP sensor.
Repair Instructions
Perform the Diagnostic Repair Verification (Verification Tests) after completing the diagnostic procedure.
* Clutch Pedal Position Sensor Replacement (Service and Repair)
* Control Module References (Programming and Relearning) for ECM replacement, setup and programming.
