P0010
DTC P0010
CIRCUIT DESCRIPTION
The camshaft position (CMP) actuator system is comprised of 4 CMP actuator solenoids, 4 oil control valves, and 4 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 incorrect voltage on one of these circuits, DTC P0010, P0013, P0020, P0023 sets.
DTC DESCRIPTORS
This diagnostic procedure supports the following DTCs:
- DTC P0010 Intake Camshaft Position (CMP) Actuator Solenoid Control Circuit Bank 1
- DTC P0013 Exhaust Camshaft Position (CMP) Actuator Solenoid Control Circuit Bank 1
- DTC P0020 Intake Camshaft Position (CMP) Actuator Solenoid Control Circuit Bank 2
- DTC P0023 Exhaust Camshaft Position (CMP) Actuator Solenoid Control Circuit Bank 2
CONDITIONS FOR RUNNING THE DTC
- DTC 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.
- This diagnostic runs continuously.
CONDITIONS FOR SETTING THE DTC
- The ECM detects incorrect voltage 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.
