Vacuum Control Solenoid Valve Check

NOTE: Applies to vehicles equipped with traction control only.

NOTE: When disconnecting the vacuum hose, always make a mark so that it can be reconnected at original position.




1. Disconnect the vacuum hose (blue stripe, green stripe) from the solenoid valve.
2. Disconnect the harness connector.




3. Connect a hand vacuum pump to the nipple to which the blue-striped vacuum hose was connected.




4. Check air-tightness by applying a vacuum with voltage applied directly from the battery to the solenoid valve and without applying voltage.




5. Measure the resistance between the terminals of the solenoid valve.
Standard value: 36-44 Ohm [at 20 °C (68 °F)]
