EGR Control Solenoid: Testing and Inspection

1. REMOVE AIR INTAKE CHAMBER ASSEMBLY
2. DISCONNECT VACUUM HOSES AND CONNECTOR





3. INSPECT VSV FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the terminals.

Resistance: At 20°C (68°F) 30 - 34 ohm

If there is no continuity, replace the VSV.





4. INSPECT VSV FOR GROUND
Using an ohmmeter, check that there is no continuity between each terminal and the body.
If there is continuity, replace the VSV.
5. INSPECT VSV OPERATION





(a) Check that the air flows from port G to E.





(b) Apply battery voltage across the terminals.
(c) Check that the air does not flows from port G to E.
If operation is as specified, replace the VSV.
6. RECONNECT VACUUM HOSES AND CONNECTOR
7. REINSTALL AIR INTAKE CHAMBER ASSEMBLY
