P0017

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 Descriptor
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 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.
* This DTC runs continuously when the above conditions are met.

Conditions for Setting the DTC

The ECM detects that the CMP sensor pulses occur less than 9 or more than 12 crankshaft degrees outside of the normal position for 24 out of 30 engine cycles.

Action Taken When the DTC Sets

DTC P0017 is a Type B DTC.

Conditions for Clearing the MIL/DTC

DTC P0017 is a Type B DTC.

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 Verification

1. Ignition ON, observe the DTC information with a scan tool. Verify DTC P0013, P0335, P0336, P0340, P0341, P0365, or P0366 are not set.

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

2. 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:

* A crankshaft balancer bolt that is not at the correct torque. Refer to Fastener Tightening Specifications (Fastener Tightening Specifications).
* An incorrectly installed camshaft sensor
* An incorrectly installed crankshaft sensor
* An incorrectly installed camshaft actuator
* Incorrect valve timing
* A loose camshaft reluctor wheel
* A loose crankshaft reluctor wheel
* A mechanical cam actuator that is stuck in the full advance or retard position.
* A mechanical cam actuator that is slow to respond.
* Excessive crankshaft end play

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.
