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 - Intake Camshaft Position Not Plausible

DTC P0017

Crankshaft Position - Exhaust Camshaft Position Not Plausible

Circuit/System Description

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

Conditions for Running the DTC


• Before the ECM can report DTC P0016 or P0017 failed, DTCs P0010, P0013, P0335, P0336, P0338, P0341, P0342, P0343, P0366, P0367, P0368, P2088, P2089, P2090, and P2091 must run and pass.

• The engine is operating for greater than 50 s.

• The engine coolant temperature is between 0-95°C (32-203°F).

• The calculated engine oil temperature is less than 120°C (248°F).

• The DTCs run continuously when the above conditions are met for approximately 10 minutes.


Conditions for Setting the DTC


• The ECM detects a deviation in the relationship between a camshaft and the crankshaft. The ECM detects the learned camshaft angle is greater than 10 degrees advanced or 10 degrees retarded in relationship to the crankshaft.

OR

• The ECM detects the actual camshaft angle is advanced 15 degrees or retarded 21 degrees in relationship to the camshaft parked/reference position.


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.

• Observing the desired and actual camshaft angle parameters, with a scan tool before a DTC sets, may help to isolate whether a condition is specific to one camshaft, one bank, or caused by a condition with the primary crankshaft timing.

Circuit/System Testing


1. Idle the engine at normal operating temperature. Use a scan tool to read the DTC Info. DTC P0016 or P0017 should not be set.

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

• The correct installation of the camshaft sensor

• The correct installation of the crankshaft sensor

• A timing chain tensioner condition

• An incorrectly installed timing chain

• Excessive play in the timing chain or sprockets

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

• A timing chain that jumped teeth

3. 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.


• Timing Chain Tensioner Replacement (LDK/A20 NHT)

• Camshaft Timing Chain Adjustment

• Primary Timing Chain Replacement
