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





NOTICE:
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.
