Conditions for Setting the DTC
The ECM detects that the CMP sensor pulses occur more than 11 crank degrees before, or 11 crank degrees after, nominal position for 24 out of 30 engine cycles.
Circuit/System Verification
Start the engine.
Allow the engine to reach normal operating temperature.
Allow the engine to idle.
Observe the DTC information with a scan tool.
⇒ If the scan tool indicates P0016 has failed this ignition cycle, continue with the Circuit/System Testing.
If the vehicle passes the Circuit/System Verification Test, then operate the vehicle within the Conditions For Running the DTC. You may also operate the vehicle within the conditions that are captured in the Freeze Frame/Failure Records Data List.
Circuit/System Testing
Important: You must perform the Circuit/System Verification before proceeding with Circuit/System Testing.
Inspect the engine front cover area, or review the service history of the vehicle for any recent repairs involving the timing chain, timing chain tensioner, camshaft, crankshaft, camshaft actuator, or sprockets.
⇒ If recent repairs were made, refer to Camshaft Timing Chain and Sprocket Replacement , and inspect the timing chain, timing chain tensioner, and both sprockets for proper timing alignment or indexing.
Remove the engine front cover, refer to Engine Front Cover Replacement and inspect the timing chain, timing chain tensioner, and sprockets for wear or damage. Refer to Camshaft Timing Chain and Sprocket Cleaning and Inspection.
