INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY

Resistance inspection

Using an ohmmeter, measure the resistance between the terminals.
Resistance: 6.9 to 7.9 Ω at 20C (68F) If necessary, replace the camshaft timing oil control valve assembly.

Movement inspection

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