2AZ-FE ENGINE CONTROL: CAMSHAFT OIL CONTROL VALVE: INSPECTION

INSPECTION

1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY





(a) Measure the resistance between the terminals.
Standard Resistance:





If the result is not as specified, replace the oil control valve assembly.
(b) Check the operation.




(1) Connect a positive (+) battery lead to terminal 1 and a negative (-) lead to terminal 2, and check the movement of the valve.
NOTE: Confirm that the valve moves freely and does not stick in any position.

If necessary, replace the camshaft timing oil control valve assembly.
HINT: Accumulation of foreign matter can cause minor pressure leaks. Minor pressure leaks will cause the camshaft to advance, and this will cause a DTC to be set.
