DTC Descriptors
DTC P0010
- Intake Camshaft Position Actuator Solenoid Valve Control Circuit
DTC P0013
- Exhaust Camshaft Position Actuator Solenoid Valve Control Circuit
Circuit/System Description
The camshaft position actuator system enables the engine control module (ECM) to change the timing of the camshafts while the engine is operating. The camshaft position actuator solenoid valve signal from the ECM is pulse width modulated (PWM). The ECM controls the camshaft position actuator solenoid valve duty cycle by controlling the amount of solenoid ON time. The camshaft position actuator solenoid valve controls the advance or the retard of each camshaft. The camshaft position actuator solenoid valve controls the oil flow that applies the pressure to advance or retard the camshafts.
The ECM controls the camshaft position actuator solenoid valve by supplying a 12 V pulse width modulated (PWM) signal. The ECM supplies a ground to the low reference circuit.
Conditions for Running the DTC
* The ignition switch is in run or crank position.
* The ignition voltage is between 11-32 V.
* The ECM has commanded the camshaft position actuator solenoid ON.
* DTCs P0010 and P0013 runs continuously once the above conditions are met for greater than 0.25 s.
Conditions for Setting the DTC
The ECM detects that the commanded state of the driver and the actual state of the control circuit do not match.
Action Taken When the DTC Sets
DTCs P0010, P0013, are type B DTCs.
Conditions for Clearing the DTC
DTCs P0010, P0013, are type B DTCs.
Diagnostic Aids
If the condition is intermittent, move the related harnesses and connectors, with the engine operating, while monitoring the scan tool circuit status parameters for the component. The circuit status parameters change from OK or Not Run to Malfunction if there is a condition with the circuit or a connection.

Circuit/System Verification
1. Ignition ON, command the appropriate Camshaft Position Actuator Solenoid Valve ON and OFF with a scan tool. You should hear the solenoid click when commanded ON and OFF.
Note: The engine speed may need to be increased for the status parameters to change.
2. Engine idling, observe the following scan tool control circuit status parameters:
* Intake Camshaft Position Actuator Solenoid Valve Control Circuit High Voltage Test Status
* Intake Camshaft Position Actuator Solenoid Valve Control Circuit Open Test Status
* Intake Camshaft Position Actuator Solenoid Valve Control Circuit Low Voltage Test Status
* Exhaust Camshaft Position Actuator Solenoid Valve Control Circuit High Voltage Test Status
* Exhaust Camshaft Position Actuator Solenoid Valve Control Circuit Open Test Status
* Exhaust Camshaft Position Actuator Solenoid Valve Control Circuit Low Voltage Test Status
Each parameter should display OK or Not Run.
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.
Circuit/System Testing
1. Ignition OFF, all vehicles systems OFF. It may take up to 2 min for all vehicle systems to power down. Disconnect the harness connector at the appropriate Q6 Camshaft Position Actuator Solenoid Valve.
2. Test for less than 5 ohms between the low reference circuit terminal 1 and ground.
• If greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the K20 Engine Control Module.
3. Ignition ON, test for 2-3 V between the control circuit terminal 2 and ground.
• If less than the specified range, test the control circuit for a short to ground, or an open/high resistance. If the circuit tests normal, replace the K20 Engine Control Module.
• If greater than the specified range, test the control circuit for a short to voltage. If the circuit/connections test normal, replace the K20 Engine Control Module.
4. Command the Camshaft Position Actuator Solenoid Valve ON and OFF with a scan tool. The DMM should transition from 2-3 V when commanded OFF to greater than 10 V when commanded ON.
• If the circuit voltage does not correspond to the specified values, replace the K20 Engine Control Module.
5. If all circuits/connections test normal, test or replace the Q6 Camshaft Position Actuator Solenoid Valve.
Component Testing
1. Ignition OFF, disconnect the harness connector at the appropriate Q6 Camshaft Position Actuator Solenoid Valve.
2. Test for 7-12 ohms between the terminals of the Q6 Camshaft Position Actuator Solenoid Valve.
• If not within the specified range, replace the Q6 Camshaft Position Actuator Solenoid Valve.
3. Test for infinite resistance between each terminal and the Q6 Camshaft Position Actuator Solenoid Valve housing.
• If not the specified value, replace the Q6 Camshaft Position Actuator Solenoid Valve.
