EGR Control Solenoid: Testing and Inspection

- With ignition switch OFF, disconnect coupler from SV valve.

Measuring EGR VSV Resistance:

- Check resistance between two terminals of SV valve.

Resistance of EGR SV valve: 30-38 ohms @ 20°C (68°F)

- If resistance is as specified, proceed to next operation check. If not, replace.
- Disconnect vacuum hoses from pipes.

Inspecting EGR VSV Operation:

- Blow into hose "A". Air should come out of hose "B" and not out of filter.

Inspecting EGR VSV Operation:

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

Vacuum Hose Connections:

- Connect vacuum hoses securely.
