Circuit Description

The camshaft position (CMP) actuator system is comprised of four CMP actuator solenoids, four oil control valves, and four CMP actuators. The engine control module (ECM) sends an electrical signal through the control circuits to the CMP actuator solenoids when a cam timing change is desired. The ground circuits of the CMP actuator solenoids are used as a return. If the ECM detects an open on one of these circuits, DTC P0010, P0013, P0020, P0023 sets.

Conditions for Running the DTC

•	DTC P0010, P0013, P0020, P0023, P2088, P2089, P2090, P2091, P2092, P2093, P2094, P2095 are not set.

•	The engine is running.

•	The CMP actuator has been commanded for more than 1 second.

•	The ignition voltage is between 11-26 volts.

Conditions for Setting the DTC

•	The ECM detects an open on a CMP actuator solenoid control or ground circuit.

•	The above condition is met for more than 1.6 seconds.

Action Taken When the DTC Sets

•	The control module illuminates the malfunction indicator lamp (MIL) on the second consecutive ignition cycle that the diagnostic runs and fails.

•

The control module records the operating conditions at the time the diagnostic fails. The first time the diagnostic fails, the control module stores this information in the Failure Records. If the diagnostic reports a failure on the second consecutive ignition cycle, the control module records the operating conditions at the time of the failure. The control module writes the operating conditions to the Freeze Frame and updates the Failure Records.

The CMP actuator system will be disabled until the end of the ignition cycle.

Conditions for Clearing the MIL/DTC

•	The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.

•	A current DTC, Last Test Failed, clears when the diagnostic runs and passes.

•	A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.

•	Clear the MIL and the DTC with a scan tool.

1	Did you perform the Diagnostic System Check - Vehicle?	Go to Step 2	Go to Diagnostic System Check - Vehicle in Vehicle DTC Information
2	Observe the Freeze Frame/Failure Records for this DTC. Turn OFF the ignition for 30 seconds. Start the engine. Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records. Did the DTC fail this ignition?	Go to Step 3	Go to Intermittent Conditions
3	Important: The scan tool will command the intake camshaft position (CMP) actuators as a set, and the exhaust CMP actuators as a set. Important: The CMP actuator output function will automatically raise the engine speed. Turn OFF the ignition. Disconnect the affected CMP actuator solenoid. Connect a test lamp between the control circuit of the affected CMP actuator solenoid and a good ground. Start the engine. Observe the test lamp while you command the affected CMP actuator to 30° with a scan tool. Exit the CMP actuator control function on the scan tool. Did the test lamp illuminate when commanded with a scan tool?	Go to Step 4	Go to Step 6
4	Turn OFF the ignition. Connect a test lamp between the control circuit and the ground circuit of the affected CMP actuator solenoid. Start the engine. Observe the test lamp while you command the affected CMP actuator to 30° with a scan tool. Turn OFF the ignition. Did the test lamp illuminate when commanded with a scan tool?	Go to Step 7	Go to Step 5
5	Repair the open or high resistance in the ground circuit of the affected CMP actuator solenoid. Refer to Wiring Repairs in Wiring Systems. Did you complete the repair?	Go to Step 11	--
6	Test the control circuit of the affected CMP actuator solenoid for an open and for high resistance. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 11	Go to Step 8
7	Test for an intermittent and for a poor connection at the affected CMP actuator solenoid. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems Did you find and correct the condition?	Go to Step 11	Go to Step 9
8	Test for an intermittent and for a poor connection at the engine control module (ECM). Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems Did you find and correct the condition?	Go to Step 11	Go to Step 10
9	Replace the affected CMP actuator solenoid. Refer to Camshaft Position Actuator Solenoid Valve Solenoid Replacement - Bank 1 (Right Side) Intake , Camshaft Position Actuator Solenoid Valve Solenoid Replacement - Bank 1 (Right Side) Exhaust , Camshaft Position Actuator Solenoid Valve Solenoid Replacement - Bank 2 (Left Side) Intake or Camshaft Position Actuator Solenoid Valve Solenoid Replacement - Bank 2 (Left Side) Exhaust . Did you complete the replacement?	Go to Step 11	--
10	Replace the ECM. Refer to Engine Control Module Replacement . Did you complete the replacement?	Go to Step 11	--
11	Clear the DTCs with a scan tool. Turn OFF the ignition for 30 seconds. Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle with in the conditions that you observed from the Freeze Frame/Failure Records. Did the DTC fail this ignition?	Go to Step 3	Go to Step 12
12	Observe the Capture Info with a scan tool. Are there any DTCs that have not been diagnosed?	Go to Diagnostic Trouble Code (DTC) List - Vehicle in Vehicle DTC Information	System OK
