Variable Valve Timing Actuator: Testing and Inspection

COMPONENTS INSPECTION

CAMSHAFT TIMING OIL CONTROL VALVE ASSY
a. Resistance inspection.
Using an ohmmeter, measure the resistance between the terminals.

Resistance:........................6.9 - 7.9 ohm @ 20 °C (68 °F)







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

NOTE: Confirm the valve does not adhere.

HINT: Bad returning of the valve by entrance of foreign objects causes subtle pressure leak to the advanced direction. Then, DTC can be detected.
