* Diagnostic Procedure Instructions (Initial Inspection and Diagnostic Overview)provide an overview of each diagnostic category.


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



Circuit/System Description

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

Conditions for Running the DTC

* DTCs P0335, P0336, P0340, and P0341 are not set.
* The engine is running.
* DTC P0016 runs continuously when the above conditions are met.


Conditions for Setting the DTC

The ECM detects the cam sensor pulses occur during the incorrect crankshaft position for 25 out of 35 engine cycles.

Action Taken When the DTC Sets

DTC P0016 is a Type B DTC.

Conditions for Clearing the MIL/DTC

DTC P0016 is a Type B DTC.

Diagnostic Aids

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

Circuit/System Verification

1. Observe the DTC Information with a scan tool.

• If the scan tool displays that any other DTCs also failed this ignition, Refer to Diagnostic Trouble Code (DTC) List - Vehicle (Diagnostic Trouble Code Descriptions).

2. Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame Records data.


Circuit/System Testing

Inspect for an incorrectly installed timing chain, excessive play in the timing chain, or for a timing chain that jumped teeth. Refer to Camshaft Timing Drive Chain Alignment Diagram (Locations) and Camshaft Timing Drive Components Cleaning and Inspection ().

Repair Instructions

Perform the Diagnostic Repair Verification (Verification Tests) after completing the diagnostic procedure.
