DTC P0011 or P0014 Diagnostic Instructions Perform the Diagnostic System Check - Vehicle (See: Testing and Inspection\Initial Inspection and Diagnostic Overview) prior to using this diagnostic procedure. Review Strategy Based Diagnosis (See: Testing and Inspection\Initial Inspection and Diagnostic Overview) for an overview of the diagnostic approach. Diagnostic Procedure Instructions (See: Testing and Inspection\Initial Inspection and Diagnostic Overview) provides an overview of each diagnostic category. DTC Descriptors DTC P0011 Intake Camshaft Position (CMP) System Performance DTC P0014 Exhaust Camshaft Position (CMP) System Performance Diagnostic Fault Information Circuit/System Description The camshaft position (CMP) actuator is attached to each camshaft and is hydraulically operated in order to change the angle of the camshaft relative to crankshaft position (CKP). The CMP actuator solenoid is controlled by the control module. The control module sends a pulse width modulated 12-volt signal to a CMP actuator solenoid. The solenoid controls the amount of engine oil flow to a CMP actuator. The CMP actuator can change the camshaft angle a maximum of 25 degrees. The control module increases the pulse width to accomplish the desired camshaft operation. Conditions for Running the DTC The engine is running. Conditions for Setting the DTC The ECM detects an open, short to ground, or a short to voltage on the high control circuit or an open on the low reference circuit for more than 0.25 second. Action Taken When the DTC Sets DTCs P0011 and P0014 are Type B DTCs. Conditions for Clearing the MIL/DTC DTCs P0011 and P0014 are Type B DTCs. Reference Information Schematic Reference Engine Controls Schematics (LAT) (See: Powertrain Management\Diagrams\Electrical)Engine Controls Schematics (LE5) (See: Powertrain Management\Diagrams\Electrical) Connector End View Reference Component Connector End Views (See: Diagrams\Connector Views) Electrical Information Reference Circuit Testing (See: Testing and Inspection\Component Tests and General Diagnostics) Connector Repairs (See: Testing and Inspection\Component Tests and General Diagnostics) Testing for Intermittent Conditions and Poor Connections (See: Testing and Inspection\Component Tests and General Diagnostics) Wiring Repairs (See: Testing and Inspection\Component Tests and General Diagnostics) Scan Tool Reference Control Module References (See: Testing and Inspection\Programming and Relearning) for scan tool information Circuit/System Verification Ensure the vehicle has the proper oil viscosity. Observe the engine oil level. The engine oil level should be within the operating range. Allow the engine to reach operating temperature. Increase the engine speed to 1,500 RPM. Command each CMP actuator to 25 percent. The CMP actuator angle desired parameter should match the CMP actuator actual parameter. 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 data. Circuit/System Testing With the ignition ON, measure for battery voltage between the CMP actuator solenoid control of the affected actuator and a ground. ¤ If less than battery voltage, test the CMP actuator control circuit for an open, short to ground. If the circuit tests normal, replace the control module. Connect a test lamp between the CMP actuator solenoid control of the affected actuator and a good ground. The test lamp should not illuminate. ¤ If the test lamp illuminates, test the CMP actuator control circuit for a short to voltage. If the circuit tests normal, replace the control module. Command each CMP actuator solenoid between 0-50 percent. The test lamp should turn ON and OFF. ¤ If the test lamp does not turn ON and OFF, test the CMP actuator control circuit for high resistance. If the circuit tests normal, replace the control module. Connect a test lamp between the low reference circuit of the CMP actuator solenoid of the affected actuator and battery voltage. The test lamp should illuminate. ¤ If the test lamp does not illuminate, test the low reference circuit for an open, high resistance. If the circuit tests normal, replace the control module. Determine that the vehicle has the correct engine oil. Refer to Service and Appearance Care in the owner's manual. ¤ If the engine oil life system monitor displays the Change Oil Soon message, the engine oil is more than one year old, contains additives, or is not the correct viscosity, change the oil. Test the engine oil pressure. Refer to Oil Pressure Diagnosis and Testing (See: Engine, Cooling and Exhaust\Engine\Testing and Inspection\Component Tests and General Diagnostics). ¤ If the oil pressure is low, correct the low pressure first. Inspect each CMP actuator solenoid valve assembly for the following: Torn screens Debris on the screens Debris clogging the oil ports Missing screens Oil seepage at the solenoid connector pins Inspect for the following conditions: Excessive timing chain play Proper installation of the CMP actuator assembly Component Testing Measure the resistance of each CMP actuator solenoid valve assembly. Resistance should be between 8-12 ohms. Connect a jumper wire between the CMP actuator low reference circuit at the solenoid and a good ground. Connect a fused jumper wire to the CMP actuator high control circuit at the solenoid. Momentarily touch the fused jumper to B+. Observe the spool valve inside the CMP actuator. The spool valve should move from fully closed to fully opened position. Repair Instructions Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure. Camshaft Position Actuator Solenoid Valve Replacement (See: Engine, Cooling and Exhaust\Engine\Variable Valve Timing Solenoid\Service and Repair) Control Module References (See: Testing and Inspection\Programming and Relearning) for replacement, setup, and programming not that simple. it needs to be checked by a shop with a scope.
