EGR Control Solenoid: Testing and Inspection

1. Disconnect Vacuum Hoses (2) from Solenoid.
2. Disconnect electrical connector with Ignition "OFF".
3. Using a DVOM, check resistance between two Terminals.
4. You should have 33-39 ohms of resistance. If resistance is within specification proceed to step 5. If not, replace Solenoid.
5. Blow into tube "A", air should exhaust through filter, not tube "B".
6. Reconnect Electrical Connector.
7. Ignition "ON", ground Diagnosis Switch Terminal.
8. Blow air into tube "A", air should exhaust from tube "B" now.

If VSV Solenoid fails the check, replace VSV.
