DTC Descriptor
DTC P0010
- Intake Camshaft Position (CMP) Actuator Solenoid Control Circuit
Diagnostic Fault Information
Circuit/System Description
The CMP actuator solenoid enables the powertrain control module (PCM) to change the intake camshaft timing while the engine is running. The CMP actuator solenoid contains a spool valve that controls the advance of the camshaft. The CMP actuator solenoid valve is controlled with a pulse width modulated (PWM) signal from the PCM. The CMP sensor monitors the camshaft position or the camshaft angle, and compares that position or phase to the crankshaft position (CKP) sensor signal. The PCM determines whether the camshaft angle is correct by comparing the actual camshaft position to the target camshaft position. By continuously monitoring the input of the CMP sensor and the CKP sensor the PCM can detect a fault in the CMP actuator system.
Conditions for Running the DTC
* The ignition is ON.
* DTC P0010 runs continuously once the above condition is met.
Conditions for Setting the DTC
The PCM detects an open or a short in the CMP actuator solenoid control circuit.
Action Taken When the DTC Sets
DTC P0010 is a type A DTC.
Conditions for Clearing the DTC
DTC P0010 is a type A DTC.
Diagnostic Aids
Scan tool output control of the CMP actuator solenoid valve is disabled as soon as DTC P0010 sets.

Circuit/System Verification
Note: All CMP actuator system DTCs must be cleared before the CMP actuator solenoid scan tool output control is enabled.
1. Engine running at normal operating temperature, command the CMP actuator solenoid ON with the scan tool. The engine should run rough or stall.
2. 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 at the camshaft position (CMP) actuator solenoid.
2. Ignition OFF, test for less than 10 ohm between the CMP low control circuit terminal 2 and ground G104.
• If greater than the specified range, test the CMP low control circuit for an open/high resistance. If the circuit tests normal, replace the PCM.
3. Disconnect the PCM harness connector X2 at the PCM.
4. Ignition ON, test for infinite resistance between the CMP low control circuit terminal 2 and ground G104.
• If less than the specified range, repair the short to ground in the CMP low control circuit.
5. Engine running, connect the CMP actuator solenoid to B+ and ground with a pair of 10 A fused jumper wires. Verify the engine runs rough or stalls.
• If the engine does not run rough or stall, test or replace the CMP actuator solenoid.
6. Test the solenoid high control circuit terminal 1 for a short or an open/high resistance.
• If the circuit tests normal, replace the PCM.
Component Testing
1. Ignition OFF, disconnect the harness connector of the CMP actuator solenoid.
2. Test for 6-8 ohm at 20°C (68°F) between the actuator solenoid terminals.
• If not within the specified range, replace the CMP actuator solenoid.
3. Test for infinite resistance between each terminal of the CMP actuator solenoid and the CMP actuator solenoid housing.
• If less than the specified value, replace the CMP actuator solenoid valve.
Repair Instructions
