Component Inspection

NOTE: When disconnecting the vacuum hose, place an identification mark on it for proper re-connection.

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





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





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





(5) Measure the resistance between the solenoid valve terminals.

Standard value: 36 - 44 Ohms [at 20°C (68°F)]
