Here is what I show for this code here on this year and model.
Important: Incorrect engine oil viscosity, aftermarket engine oil additives, or engine oil that overdue for changing, can greatly affect the performance of the camshaft actuator.
1. Ignition OFF, disconnect C112.
2. Test for less than 1 ohm of resistance between the low reference circuit ECM side, terminal E and ground.
◊If greater than 1 ohm, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the ECM.
3. Remove the water pump from the engine.
4. Inspect and test the remaining wire harness from C112 to the CMP solenoid for an open/high resistance, or a short to ground.
◊If the circuit tests normal, perform the component testing for the CMP actuator solenoid.
◊If the CMP solenoid and the circuit test normal, then refer to Camshaft Position Actuator Magnet Cleaning and Inspection and Camshaft Position Actuator Solenoid Valve Inspection (On-Vehicle) Camshaft Position Actuator Solenoid Valve Inspection (Off-Vehicle).
Important: You must perform the Circuit/System Testing before proceeding with Component Testing.
Test for 5.9-6.9 ohms of resistance at 20°C, or 68°F between the solenoid control terminal 2 and the low reference terminal 1 at the CMP actuator solenoid.
If the resistance is not with in the specified range, then replace the CMP actuator solenoid. Refer to Camshaft Position Actuator Magnet Replacement.
Important: Do not allow electrical current to flow through the CMP actuator solenoid for more than 1-2 seconds, or damage to the solenoid may occur.
Point the CMP actuator solenoid vertically, towards a shop towel. Connect one end of a fused jumper wire to the CMP actuator solenoid control circuit terminal 2 and 12 volts. Connect a second jumper wire to the low reference circuit terminal 1 and momentarily connect to ground. The CMP actuator solenoid should immediately extend.
If the CMP actuator solenoid pintle does not extend, then replace the CMP actuator solenoid. Refer to Camshaft Position Actuator Magnet Replacement.
This test procedure requires that the vehicle battery has passed a load test and is completely charged. Refer to Battery Inspection/Test. See: Starting and Charging > Component Tests and General Diagnostics > Battery Inspection/Test
1. Observe the engine oil level. The engine oil level should be within the operating range on the oil indicator stick.
2. Start the engine. Allow the engine to reach normal operating temperature.
3. Monitor the engine oil pressure parameter value with the scan tool. The engine oil pressure must be at or above the minimum hot oil pressure values. Refer to Engine Mechanical Specifications (RPO LY5 VIN J) Engine Mechanical Specifications (RPO LC9 VIN 3) Engine Mechanical Specifications (RPO LY2 VIN C) Engine Mechanical Specifications (RPO LH6 VIN M) Engine Mechanical Specifications (RPO LMG VIN 0) Engine Mechanical Specifications (RPO LY6 VIN K) Engine Mechanical Specifications (RPO L76 VIN Y) Engine Mechanical Specifications (RPO L92 VIN 8).
4. Using the output control function of the scan tool, command the CMP actuator solenoid to 25 degrees. The CMP Desired parameter value should match the CMP Angle parameter value.
5. Observe the CMP Variance value, on the scan tool. The CMP Variance value will increment for several seconds, until the CMP Angle value matches the Desired CMP value. The CMP Variance value should then return to 0 degrees.
◊If the vehicle passes the Circuit/System Verification, then operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that are captured in the Freeze Frame/Failure Records Data list.
Let me know if you need anything else and feel free to rate my help here as this is how I receive credit for my time.
