2010 Cadillac CTS Sedan AWD V6-3.6L Page 1685
Circuit/System Description
The clutch pedal position (CPP) sensor 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 volt when the clutch pedal is applied.
Conditions for Running the DTC
DTCs P0335, P0336, P0502, P0503, P0607, P0808, or P080A are not set.
Conditions for Setting the DTC
The CPP sensor is stuck in range.
Action Taken When the DTC Sets
P0806 is a Type A DTC.
Conditions for Clearing the MIL/DTC
P0806 is a Type A DTC.

Circuit/System Verification
1. 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.
2. 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/Tremec 6-Speed - Manual Transmission).
3. 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.
