P0016-CRANKSHAFT/CAMSHAFT TIMING MISALIGNMENT





For a complete wiring diagram, refer to the Wiring Information Electrical Diagrams.

- When Monitored:
With the engine speed between 480 and 6,816 RPM and no Camshaft Position (CMP) or Crankshaft Position (CKP) sensor Diagnostic Trouble Codes (DTCs) detected.

- Set Condition:
Powertrain Control Module (PCM) detects an error when the camshaft position is out of phase with the crankshaft position. One Trip Fault. Three good trips to turn off the Malfunction Indicator Lamp (MIL).





WARNING: On vehicles equipped with the high voltage system, you must thoroughly read and follow all High Voltage Safety procedures. In addition, before performing any diagnostic or service procedure near a high voltage component, you must perform the High Voltage Power Down. Failure to follow these instructions may result in possible serious or fatal injury

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Pre-Diagnostic Troubleshooting Procedure.
