2GR-FE ENGINE CONTROL SYSTEM: CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY:

INSPECTION

1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY
(a) Resistance inspection.
(1) Using an ohmmeter, measure the resistance between the terminals.
Standard resistance:
6.9 to 7.9 Ohms at 20°C (68°F)
If necessary, replace the camshaft timing oil control valve assembly.






(b) Movement inspection.
(1) Connect the positive (+) lead from the battery to terminal 1 and the 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 objects causes subtle pressure leaks. The subtle pressure leaks will cause the camshaft to advance, and this will cause a DTC to be set.
