DTC P0016 or P0017

Diagnostic Instructions

•	Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure.

•	Review Strategy Based Diagnosis for an overview of the diagnostic approach.

•	Diagnostic Procedure Instructions provides an overview of each diagnostic category.

DTC Descriptors

DTC P0016: Crankshaft Position (CKP)-Intake Camshaft Position (CMP) Correlation

DTC P0017: Crankshaft Position (CKP)-Exhaust Camshaft Position (CMP) Correlation

The engine control module (ECM) uses the crankshaft position (CKP) sensor and the intake and exhaust camshaft position (CMP) sensor information to monitor the correlation between the crankshaft, intake, and exhaust camshaft position.

Conditions for Running the DTC

•	DTC P0335, P0336, P0340, P0341, P0365, P0366, P0641, and P0651 are not set.

•	The engine is cranking or running.

•	The crankshaft and camshaft position signals are synchronised.

•	The camshaft position actuator is in the parked position.

•	DTC P0016 and P0017 run continuously once the above conditions are met.

Conditions for Setting the DTC

The ECM detects a camshaft that is greater than 10 degrees advanced, or 10 degrees retarded, in relationship to the crankshaft.

Action Taken When the DTC Sets

DTCs P0016 and P0017 are type B DTCs.

Conditions for Clearing the DTC

DTCs P0016 and P0017 are type B DTCs.

Diagnostic Aids

Inspect the engine for any recent engine mechanical repairs. An incorrectly installed camshaft, camshaft actuator, camshaft sensor, crankshaft sensor or timing chain can cause this DTC to set.

Circuit/System Testing

Ignition ON, observe the DTC information with a scan tool. Verify that none of the following DTCs are set. DTC P0010, P0013, P0335, P0336, P0340, P0341, P0365, or P0366.

⇒	If any of the DTCs listed are set refer to Diagnostic Trouble Code (DTC) List - Vehicle for further diagnosis.

Idle the engine at normal operating temperature. DTCs P0016 or P0017 should not set.

⇒	If a DTC sets, inspect for the following and repair as necessary:

•	The correct installation of the camshaft sensors

•	The correct installation of the crankshaft sensor

•	A timing chain tensioner condition

•	An incorrectly installed timing chain

•	Excessive play in the timing chain

•	A mechanical cam actuator that is stuck in the full advance or retard position

•	A timing chain that jumped teeth

Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
