DTC P0017

Diagnostic Instructions

* Perform the Diagnostic System Check - Vehicle (Diagnostic System Check - Vehicle) prior to using this diagnostic procedure.
* Review Strategy Based Diagnosis (Strategy Based Diagnosis) for an overview of the diagnostic approach.
* Diagnostic Procedure Instructions (Diagnostic Procedure Instructions) provides an overview of each diagnostic category.

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

Circuit/System Description

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

Conditions for Running the DTC

* DTCs P0335, P0336, P0365, P0366, P0641, and P0651 are not set.
* The engine is cranking or running.
* The engine speed is less than 1,200 RPM and the CMP actuator is commanded to the home or parked position.
* These DTCs run continuously when the above conditions are met.

Conditions for Setting the DTC

The ECM detects that the CMP sensor pulse is more than 16.31 degrees out of sequence with the corresponding crank sensor pulse.

Action Taken When the DTC Sets

DTCs P0016 and P0017 are Type B DTCs.

Conditions for Clearing the MIL/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

1. Ignition ON, observe the DTC information with a scan tool. Verify that none of the following DTCs are set. DTC P0013, P0014, P0335, P0336, P0365, or P0366.

• If a DTC is set, refer to Diagnostic Trouble Code (DTC) List - Vehicle (Diagnostic Trouble Code Descriptions) for further diagnosis.

2. Ignition OFF, inspect the crankshaft balancer bolt for the correct torque. Refer to Fastener Tightening Specifications (Fastener Tightening Specifications) for specification.
3. Idle the engine at normal operating temperature. DTC P0017 should not set.

• 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
* A mechanical cam actuator that is stuck in the full advance or retard position.
* A timing chain that jumped teeth
* A loose camshaft reluctor wheel
* A loose crankshaft reluctor wheel
* Excessive crankshaft end play

4. 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.
