EGR Control Solenoid: Testing and Inspection

1. With ignition switch OFF, disconnect coupler from solenoid vacuum valve.





2. Check resistance between two terminals of solenoid vacuum valve.

Resistance: 33 - 39 Ohms

If resistance is as specified, proceed to next operation check. If not, replace.
3. Disconnect vacuum hoses from EGR pressure transducer and throttle body.





4. Blow into nozzle "A". Air should come out of filter and not out of nozzle "B".





5. Connect 12V-battery to solenoid vacuum valve terminals. In this state, blow nozzle "A". Air should come out of nozzle "B" and not out of filter. If check result is not as described above, replace EGR solenoid vacuum valve.
6. Connect solenoid vacuum valve coupler securely.
7. Connect vacuum hose securely.
