![]() If the circuit tests normal, replace the ECM.ĥ. If the test lamp illuminates, test the control circuit for short to voltage. Verify that a test lamp does not illuminate between the low reference circuit terminal B and the control circuit terminal A. If greater than the specified range, test the low reference circuit for an open/high resistance.ģ. Test for less than 5 ohms between the low reference circuit terminal B and ground. Ignition OFF, disconnect the CMP actuator solenoid harness connector at the CMP actuator solenoid.Ģ. Otherwise continue with the following troubleshooting.ġ. ![]() Resistance should be between 8-12 ohms, if it is not within specification, replace the defective solenoid valve. ![]() HINT: Measure the resistance of each CMP actuator solenoid valve assembly. Intake Camshaft Position (CMP) Actuator Solenoid The control module increases the pulse width to accomplish the desired camshaft operation. The CMP actuator can change the camshaft angle a maximum of 25 degrees. The solenoid controls the amount of engine oil flow to a CMP actuator. The control module sends a pulse width modulated 12-volt signal to a CMP actuator solenoid. The CMP actuator solenoid is controlled by the control module. SUMMARY: P0010 - Intake Camshaft Position (CMP) Actuator Solenoid Control Circuit Fault 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). RELATED VEHICLES: 2009 Cobalt, HHR, Pontiac G5 2.2L Check to make sure the wires are clean and tight and not corroded. It sounds like either the cam shaft position sensor is going bad or there is a wiring problem.
