Checking Components

Checking Components







NOTE: If the diagnostic trouble code (DTC) for correlation between the crankshaft position and camshaft position is stored, it must be fault-traced first.

HINT: Contaminants in the engine oil can damage components in the variable valve timing (VVT) unit which can cause function faults.

Check the engine oil grade. Check especially for contaminants.

Remove the camshaft reset valve, check the reset valve and the oil ducts in the cylinder head. Check for contaminants and blockages.

Try a new camshaft reset valve if no fault is found or if the above remedies do not rectify the fault.

HINT: The fault can also be caused by an internal fault in the variable valve timing (VVT) unit. If the above fault-tracing/remedies do not rectify the fault, the variable valve timing (VVT) unit may be damaged.

Remedy as necessary.
