4GR-FSE ENGINE CONTROL: CAMSHAFT OIL CONTROL VALVE: INSPECTION

1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY

(a) Measure the resistance between the terminals.





Standard resistance:

6.9 to 7.9 Ohms at 20°C (68°F)

If the result is not as specified, replace the oil control valve.

(b) Connect a battery positive (+) lead to terminal 1 and negative (-) lead to terminal 2, and check the movement of the valve.





OK:





If the result is not as specified, replace the oil control valve.

NOTICE:
Accumulation of foreign matter can cause minor pressure leaks. Minor pressure leaks in the intake side oil control valve will cause the intake camshaft to advance. Minor pressure leaks in the exhaust side oil control valve will cause the exhaust camshaft to retard. The inappropriate camshaft timing that results from these leaks will cause a DTC to be set.
