Variable Valve Timing Actuator: Testing and Inspection
Component Inspection
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 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 connect 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 cam to advance, and this
will cause a DTC to be set.
