EGR Vacuum Switching Valve (Samurai & Sidekick
- Turn ignition off. Disconnect Green ECM connector and VSV connector. On Samurai and Sidekick, VSV is Blue in color and mounted near front right side of valve cover. On Swift DOHC, solenoid is mounted behind engine, near center of firewall. on Swift SOHC, solenoid is located between distributor and EGR modulator. Turn ignition on.
- Check for battery voltage on appropiate wire terminal at VSV connector. See EGR VSV POWER TERMINAL IDENTIFICATION
table. if battery voltage is present, go to next step. If battery voltage is not present, check circuit between VSV and EFI main/control relay. If circuit is okay, check EFI main relay. See EFI MAIN RELAY under RELAYS & SOLENOIDS
.EGR VSV POWER TERMINAL IDENTIFICATION
APPLICATION WIRE COLOR Samurai & Sidekick Blue/Black Swift White/Blue - Turn ignition off. Check resistance between solenoid terminals. If resistance is not 33-39 ohms, replace solenoid. Disconnect upper and lower hoses from VSV. Connect short section of hose to lower horizontal port of solenoid. Blow air through hose connected to solenoid. Air should exit through filter.
- If air does not exit through filter, replace solenoid. If air exits through filter, energize solenoid by applying battery voltage to appropiate wire terminal and ground the other terminal. See the EGR VSV POWER TERMINAL IDENTIFICATION table. Solenoid should click. Blow air through hose connected to solenoid. Air should now exit through other port and not through filter. If test results are not as specified, replace solenoid.
