P0011 and P0014, Diagnostic AidsThe engine oil condition has a major impact on the camshaft actuator system. A low oil level condition may set this DTC. The engine may require an oil change. Inquire with the customer when the last oil change was performed. You may also monitor the scan tool Engine Oil Life parameter. Advise the customer an oil change may be required. Inspect the engine for any recent engine mechanical repairs. An incorrectly installed camshaft, camshaft actuator, or timing chain can cause this DTC to set. Circuit/System VerificationNote: The engine oil level and the oil pressure are critical to the correct operation of the camshaft position actuator system. Verify that the engine has the correct oil level and the correct oil pressure before continuing with this diagnostic. If a crankshaft or camshaft position sensor DTC is set, the Camshaft Position Actuator output control will not function. Ignition ON, observe the scan tool DTC information. Verify that DTC  P0016, P0017, P0335, P0336, P0340, P0341, P0365, P0366, P1516, P2101, or P2119 is not set. If a DTC is set, refer to Diagnostic Trouble Code (DTC) List - Vehicle for further diagnosis. Engine idling, command the appropriate Camshaft Position Actuator from 0 degrees to 20 degrees and back to zero while observing the appropriate scan tool Camshaft Position Variance parameters. The Camshaft Position Variance should be less than 2 degrees in each of the commanded states. 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 TestingIgnition OFF, disconnect the harness connector at the appropriate Camshaft Position Actuator Solenoid Valve. Test for less than 5 Ω between the low reference circuit terminal B 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. Note: A test lamp must be used for this test. The control circuit is pulled-up to a low current voltage, 1.5–3.5 V on the control circuit is normal. Ignition ON, Engine OFF, verify that a test lamp does not illuminate between the control circuit terminal A and ground. If the test lamp illuminates, test the control circuit for a short to voltage. If the circuit tests normal, replace the ECM. Ignition ON, command the appropriate Camshaft Position Actuator Solenoid Valve from OFF to ON with a scan tool while observing the scan tool Camshaft Position Actuator Solenoid Valve Contol Circuit Low Voltage Test Status. The value should toggle between OK and Not Run in each of the commanded states. If the parameter 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. Remove the Camshaft Position Actuator Solenoid Valve . Verify the following conditions do not exist with the Camshaft Position Actuator Solenoid Valve: Torn, restricted, mis-positioned, or missing screens at the CMP actuator solenoid Engine oil leak between the oil sealing lands of the CMP actuator solenoid. Inspect the lands of the CMP actuator solenoid for nicks. Oil seepage at the CMP actuator solenoid connectorIf a condition is found, replace Camshaft Position Actuator Solenoid Valve.Note: After swapping toe solenoids, install jumper wires to the appropriate terminals of the harness connectors and the solenoids. Ignition OFF, swap the appropriate Camshaft Position Actuator Solenoid Valve with a Camshaft Position Actuator Solenoid Valve that is operating correctly. Engine idling. Command the appropriate Camshaft Position Actuator from 0 degrees to 20 degrees and back to zero while observing the appropriate scan tool Camshaft Position Variance parameters. The Camshaft Position Variance should be less than 2 degrees in each of the commanded states. If greater than the specified value, replace the mechanical camshaft position actuator.If all circuits/connections test normal, test or replace the Camshaft Position Actuator Solenoid Valve . Component TestingIgnition OFF, disconnect the harness connector at the appropriate Camshaft Position Actuator Solenoid Valve . Test for 9.5–15 Ω between the control terminal A and the low reference circuit terminal B of the Camshaft Position Actuator Solenoid Valve . If not within the specified range, replace the Camshaft Position Actuator Solenoid Valve . Test for infinite resistance between each terminal and the Camshaft Position Actuator Solenoid Valve housing. If not the specified value, replace the Camshaft Position Actuator Solenoid Valve

P0013Circuit/System VerificationNote: If a crankshaft or camshaft position sensor DTC is set, the Camshaft Position Actuator output control will not function. Ignition ON, observe the DTC information with a scan tool. Verify DTC P0335, P0336, P0340, and P0341 is not set. If any of the DTCs are set, refer to Diagnostic Trouble Code (DTC) List - Vehicle for further diagnosis. Engine idling, command the Camshaft Position Actuator to 10° while observing the following control circuit status parameters with a scan tool: Exh or Int CMP Sol Ckt Open Test Status Exh or Int CMP Sol Ckt Short Gnd Test Status Exh or Int CMP Sol Ckt Short Volts Test Status Each parameter should display OK or Not RunOperate 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 TestingIgnition OFF, disconnect the harness connector at the appropriate Camshaft Position Actuator Solenoid Valve . Test for less than 5 Ω between the low reference circuit terminal B 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. Note: A test lamp must be used for this test. The control circuit is pulled-up to a low current voltage, 1.5–3.5 V on the control circuit is normal. Ignition ON, Engine OFF, verify that a test lamp does not illuminate between the control circuit terminal A and ground. If the test lamp illuminates, test the control circuit for a short to voltage. If the circuit tests normal, replace the ECM. Connect the DMM black lead to the control circuit terminal A. Connect the DMM red lead to B+. Set the DMM on the diode setting. Command the CMP actuator solenoid 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. If all circuits/connections test normal, test or replace the appropriate Camshaft Position Actuator Solenoid Valve. Component TestingIgnition OFF, disconnect the harness connector at the appropriate Camshaft Position Actuator Solenoid Valve . Test for 5–9 Ω between the control terminal A and the low reference circuit terminal B of the Camshaft Position Actuator Solenoid Valve . If not within the specified range, replace the Camshaft Position Actuator Solenoid Valve . Test for infinite resistance between each terminal and the Camshaft Position Actuator Solenoid Valve housing. If not the specified value, replace the Camshaft Position Actuator Solenoid Valve.
