DTC Descriptor 

This diagnostic procedure supports the following DTCs: 

• 

DTC P0008 – Engine Position System Performance (Bank 1) 

• 

DTC P0009 – Engine Position System Performance (Bank 2) 

• 

DTC P0016 – Crankshaft / Intake Camshaft Position Not Plausible (Bank 1) 

Circuit Description 

The engine control relay applies ignition positive battery voltage to the camshaft position (CMP) actuator solenoids 
through the ignition voltage circuit. 

Using a device called a driver, the ECM applies a pulse width modulated (PWM) ground to the individual CMP solenoid 
control circuit. This controls the oil pressure that advances or retards each camshaft position. 

The ECM compares the camshaft position to the crankshaft position to detect CMP system malfunction. A CKP / CMP 
sensor correlation DTC sets if the ECM detects a deviation between the target position of the camshaft and the 
crankshaft position. 

Conditions for Running the DTC 

DTC P0008 or P0009 

Run continuously once the following conditions are met. 

Engine Management – V6 – Diagnostics 

Page 6C1-2–61 

 

• 

DTCs P0341, P0342, P0343, ran and passed: 

• 

The engine is running. 

• 

The ECM has learned the camshafts position. 

DTC P0016 

Run continuously once the following conditions are met. 

• 

DTCs P0335, P0336, P0338, P0341, P0342 and P0343 ran and passed: 

• 

The calculated engine oil temperature is less than 95

°C. 

• 

The engine coolant temperature is 20 – 90

°C. 

• 

The engine is running for greater than 5 seconds. 

Conditions for Setting the DTC 

DTC P0008 

The ECM detects that both camshafts on bank 1 of the engine are misaligned with the crankshaft. 

DTC P0009 

The ECM detects that both camshafts on bank 2 of the engine are misaligned with the crankshaft. 

DTC P0016 

The ECM detects the following deviation in the correlation between the camshaft position and the crankshaft position for 
greater than 10 minutes: 

• 

a camshaft position is too advanced in relationship to the crankshaft, or 

• 

a camshaft position is too retarded in relationship to the crankshaft. 

Conditions for Clearing DTC 

The CKP / CMP sensor correlation DTCs are Type B DTCs. Refer to 1.4  Diagnostic Trouble Codes in this Section, for 
action taken when Type B DTCs set and conditions for clearing Type B DTCs. 

Additional Information 

• 

Refer to 6C1-1 Engine Management – V6 – General Information for details of the CMP system operation. 

• 

Inspect the engine for recent engine mechanical repairs. Incorrect camshaft, camshaft actuator or timing chain 
installation will trigger these DTCs. 

• 

The engine oil condition has a major impact on the operation of the camshaft actuator. 

• 

A low oil level may set these DTCs. 

• 

For an intermittent fault condition, refer to 5.2 

Intermittent Fault Conditions in this Section. 

• 

Since fault condition in a wiring connector may trigger DTCs, always test the connectors related to this diagnostic 
procedure for shorted terminals or poor wiring connection before replacing any component. Refer to 8A Electrical - 
Body and Chassis for information on electrical fault diagnosis. 

• 

To assist diagnosis, refer to 3 

Wiring Diagrams and Connector Charts in this Section, for the system wiring 

diagram and connector charts. 

Test Description 

The following numbers refer to the step numbers in the diagnostic table: 

3 

A fault condition in any of the listed sensors will trigger these DTCs. 

5 

Incorrect camshaft, camshaft actuator or timing chain installation will trigger these DTCs.
