EGR Vacuum Switching Valve (VSV)
- Turn ignition off. Disconnect connector from VSV. On Samurai and Sidekick, VSV is mounted near right side of valve cover, at front of engine. On Swift DOHC, VSV is mounted behind engine, near center of firewall. On Swift SOHC, VSV is located between distributor and EGR modulator.
- On all models, turn ignition on and then off. Check resistance between VSV terminals. If resistance is not 30-39 ohms at 68°F (20°C), replace VSV.
- Disconnect upper and lower hoses from VSV. Connect short section of hose to lower horizontal port of VSV. Blow air through hose connected to VSV. Air should exit through other port, not filter.
- If air exits through filter, replace solenoid. If air does not exit through filter, energize solenoid by applying battery voltage to appropriate wire terminal and ground to other terminal. Refer to the EGR VACUUM SWITCHING VALVE TERMINAL IDENTIFICATION table. Solenoid should click. Blow air through hose connected to solenoid. Air should now exit through filter and not through other port. If test is not as specified, replace solenoid.
