Diagnostic Fault Information






Circuit/System Description

A camshaft position (CMP) actuator solenoid valve is attached to each camshaft and is operated hydraulically in order to change the angle of the camshaft relative to crankshaft position. The CMP actuator solenoid valves are controlled by the engine control module (ECM). The ECM sends a pulse width modulated signal to the CMP actuator solenoid valve. The CMP actuator solenoid valves control the amount of engine oil flow to the CMP actuator solenoid valve. The CMP actuator solenoid valve can change the camshaft angle by a maximum of 20°. The ECM increases the pulse width to accomplish the desired camshaft operation.

The ECM controls the solenoid with a solid state device called a driver. The driver is equipped with a feedback circuit that is pulled-up to a voltage. The ECM can determine if the control circuit is open, shorted to ground, or shorted to a voltage by monitoring the feedback voltage.

Conditions for Running the DTC

* The engine is running.
* The ignition voltage is greater than 11 V.
* The camshaft position actuator is commanded ON.
* The DTCs run continuously when the above conditions are met.

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 for greater than 5 s.

Action Taken When the DTC Sets

DTCs P0010 and P0013 are Type B DTCs.

Conditions for Clearing the DTC

DTCs P0010 and 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 Camshaft Position Actuator Solenoid Valve Control Circuit status parameters. The circuit status parameters will change from OK, or Not Run, to Malfunction if there is a condition with the circuit or connection.

Circuit/System Verification

1. Engine running, observe the scan tool control circuit status parameters listed below:

* Intake/Exhaust Camshaft Position Actuator Solenoid Valve Control Circuit High Voltage Test Status
* Intake/Exhaust Camshaft Position Actuator Solenoid Valve Control Circuit Open Test Status
* Intake/Exhaust Camshaft Position Actuator Solenoid Valve Control Circuit Low Voltage Test Status
Each parameter should display OK or Not Run.

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 appropriate Q6 camshaft position actuator solenoid valve.
Note: A test lamp must be used for this test. The control circuit is pulled-up to a low current voltage. The current is too low to illuminate a test lamp. A voltage on the control circuit is normal.

2. Service Mode active, verify that a test lamp does not illuminate between the control circuit terminal 2 and ground.

• If the test lamp illuminates, test the control circuit for a short to voltage. If the circuit tests normal, replace the ECM.

3. Ignition OFF, all vehicles systems OFF. It may take up to for 2 minutes for all vehicle systems to power down. Test for less than 5 Ohms between the low reference circuit terminal 1 and ground.

• If greater than the specified value, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the ECM.

4. Connect the DMM negative lead to the control circuit terminal 2. Connect the DMM positive lead to B+. Set the DMM on the diode setting. Command the CMP Actuator Solenoid Valve ON and OFF with a scan tool. The DMM should transition from OL when commanded OFF to less than 1 V when commanded ON.

• If the circuit voltage does not correspond to the specified values, test the control circuit for an open/high resistance or a short to ground. If the circuit tests normal, replace the ECM.

5. If all circuits/connections test normal, test or replace the Q6 camshaft position actuator solenoid valve.

Component Testing

Static Test
1. Ignition OFF, disconnect the harness connector at the appropriate Q6 camshaft position actuator solenoid valve.
2. Test for 5.0-9.0 Ohms between the solenoid control terminal 2 and the low reference terminal 1 at the 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 of the solenoid and the solenoid housing.

• If not the specified value, replace the Q6 camshaft position actuator solenoid valve.

Dynamic Test
1. Remove the appropriate Q6 camshaft position actuator solenoid valve.
2. Install a 10 A fused jumper wire between the control circuit terminal 2 and 12 V. Momentarily install a jumper wire between the low reference terminal 1 and ground. The pintle should extend.
Note:
* The camshaft position actuator solenoid pintle should be facing downward for this test.
* Do not allow electrical current to flow through the camshaft position actuator solenoid for greater than 1-2 s.

• If the function does not perform as specified, replace the Q6 camshaft position actuator solenoid valve.
