INSPECTION
1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY
(a) Resistance inspection
(1) Using an ohmmeter, measure the resistance between the terminals.
Resistance: 6.9 to 7.9 Ω 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 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.
