SECTION: 303-01 Intake Camshaft Variable Cam Timing Actuator - Component Failure

Affected Vehicle Range:

Markets: NAS

Condition Summary:

Situation: A rattle noise may be evident from the engine compartment and/or the Malfunction Indicator Lamp (MIL) is illuminated. The Diagnostic Trouble Code (DTC) that may be logged include P0016, P0017, P0026, or P0341.

Cause: This may be caused by the 'stopper' in the intake camshaft Variable Cam Timing (VCT) actuator becoming detached, leading to the VCT actuator not functioning.

Action: Should a customer express this concern, follow the Service Instruction below.

Parts:

Tools:

• Alignment Tool, Crankshaft Position Sensor (JLR-303-1521)

Refer to the Service Instruction/Workshop Manual for any other required special tools.

Warranty:

Note: Repair procedures are under constant review, and therefore times are subject to change; those quoted here must be taken as guidance only. Always refer to TOPIX to obtain the latest repair time.

Note: DDW requires the use of causal part numbers. Labor only claims must show the causal part number with a quantity of zero.

Note: Normal Warranty procedures apply.

Component Location

1. Intake camshaft Variable Camshaft Timing (VCT) actuator location

Service Instruction:

1. Remove the camshaft cover (see TOPIX Workshop Manual, section 303-01A / 303-01B: Engine).
2. Inspect the Variable Camshaft Timing (VCT) actuator.
   • If the VCT actuator is noisy but the 'stopper' is in place, proceed to step 3.
   • If the 'stopper' is not in place in the VCT actuator, proceed to step 4.

3. Note: Clockwise movement should NOT be possible without also rotating the engine.

   Fully rotate the camshaft anti-clockwise (1) and then attempt to rotate the camshaft clockwise (2).

   • If no clockwise movement was possible without also rotating the engine, the VCT actuator is functioning correctly. Reverse the removal procedure.
   • If the camshaft rotates freely in both directions, the VCT actuator is NOT functioning correctly; proceed to step 4.
4. Renew the intake camshaft VCT actuator (see TOPIX Workshop Manual, section 303-01A / 303-01B: Engine).
