Circuit/System Verification
1. If DTC P0641 or P0651 is set, refer to Diagnostic Trouble Code (DTC) List - Vehicle (See: Diagnostic Trouble Code
Descriptions/Diagnostic Trouble Code (DTC) List - Vehicle).
2. Ignition ON, observe the scan tool CPP sensor percent parameter. The percentage should vary from 0 percent when the clutch pedal is
released, to 100 percent when the clutch pedal is in the apply position.
3. Perform the CPP learn procedure. Refer to Clutch Pedal Position Sensor Learn (See: Transmission and Drivetrain/Manual
Transmission/Transaxle/Testing and Inspection/Programming and Relearning/Aisin AY6 - Manual Transmission).
4. Operate the vehicle within the conditions for running the DTC to verify the DTC does not reset. You may also operate the vehicle within the
conditions that you observed from the Freeze Frame/Failure Records data.
Circuit/System Testing
1. Ignition OFF, disconnect the harness connector of the CPP sensor.
2. Ignition OFF, test for less than 1 ohm between the low reference circuit terminal A and the negative post of the battery.
瀚慖f greater than the specified value, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the ECM.
3. Ignition ON, test for 4.8-5.2 volts between the 5-volt reference circuit terminal C and ground.
瀚慖f 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,
