Chevy Cruze-ing along

Owners of 2011-2014 Chevrolet Cruze vehicles may complain about an intermittent engine no-crank condition. They may also note that by cycling the ignition key off and then back on, the engine may crank. This condition may be caused by the ECM receiving an intermittent exhaust camshaft position sensor (CMP) signal as soon as the ignition is turned to the on position.

This results in the ECM not sending a crank request signal because it has determined that the engine is already running. According to Chevy, do not immediately replace the exhaust CMP sensor based solely on this condition.

Connect a scan tool to the vehicle.Turn the ignition to the on position with the engine off.Perform a diagnostic system check.

If any DTC is set, address and repair as needed before proceeding. Select Engine Data. With the ignition on and engine off, observe one of the following Active Counter parameters for incrementing:

  • Exhaust CMP Active Counter
  • Exhaust Camshaft Position Active Counter

If the Active Counter parameter is incrementing, replace the exhaust CMP sensor.
