Circuit/System Verification
- 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.
- Observe the appropriate control circuit status parameters listed below with a scan tool:
- The Exhaust/Intake Camshaft Position Actuator Solenoid Valve Control Circuit Open test status
- The Exhaust/Intake Camshaft Position Actuator Solenoid Valve Control Circuit High Voltage test status
- The Exhaust/Intake Camshaft Position Actuator Solenoid Valve Control Circuit Low Voltage test status
Each parameter should display OK or Not Run
- Engine idling, command the Camshaft Position Actuator to 20 degrees while observing the following control circuit status parameters with a scan tool:
- The Exhaust/Intake Camshaft Position Actuator Solenoid Valve Control Circuit Open test status
- The Exhaust/Intake Camshaft Position Actuator Solenoid Valve Control Circuit High Voltage test status
- The Exhaust/Intake Camshaft Position Actuator Solenoid Valve Control Circuit Low Voltage test status
Each parameter should display OK or Not Run
- Engine at normal operating temperature, raise the engine speed to 2,000 RPM for 10 s. DTC P0010 or P0013 should not set.
- 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.
NOTE:
If a crankshaft or camshaft position sensor DTC is set, the Camshaft Position Actuator output control will not function.
