Variable Valve Timing Solenoid: Testing and Inspection
Component Inspection
INSPECTION
1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE RESISTANCE
Using an ohmmeter, measure the resistance between the terminals.
Resistance: 6.9 to 7.9 Ohm at 20 °C (68 °F)
2. INSPECT VALVE MOVEMENT
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 does not catch.
HINT: Bad returning of the valve by catching foreign objects causes subtle pressure leak in the advanced direction. DTCs could be detected.
