Variable Valve Timing Solenoid: Testing and Inspection
Component InspectionINTAKE VALVE TIMING CONTROL POSITION SENSOR
1. Disconnect intake valve timing control position sensor harness connector.
2. Loosen fixing bolt of the sensor.
3. Visually check the sensor for chipping.
4. Check resistance between terminals 2 and 3.
Resistance: 600 - 740 Ohm [at 20 °C (68 °F)]
If NG, replace intake valve timing control position sensor.
Component Inspection
INTAKE VALVE TIMING CONTROL SOLENOID VALVE
1. Check oil passage visually for any metal debris.
2. Supply intake valve timing control solenoid valve terminals with battery voltage.
3. Make sure that inside plunger protrudes.
If NG, replace intake valve timing control solenoid valve.
