How can I test my EGR valve?
A vacuum-controlled EGR valve is easy to test with a hand-held vacuum pump (see the image). If the EGR valve opens and the vacuum holds for more than a minute, the EGR valve works. If a vacuum diaphragm inside the EGR valve is leaking, the vacuum will drop. Once the vacuum is released, the valve should close fully.
When do you use an electronic EGR valve?
Electronic EGR valves are used in vehicles dated 1990 and up. The vehicle computer operates the valve instead of previous years EGR valves, which are operated by the engine vacuum. The procedure to test an electronic EGR is a bit different and requires a multimeter.
Is the exhaust gas recirculation valve an electronic valve?
The exhaust gas recirculation valve within your vehicle is a crucial component in reducing harmful emissions and ensuring your vehicle runs smoothly. Electronic EGR valves are used in vehicles dated 1990 and up. The vehicle computer operates the valve instead of previous years EGR valves, which are operated by the engine vacuum.
Can a multimeter be used to test EGR?
The vehicle computer operates the valve instead of previous years EGR valves, which are operated by the engine vacuum. The procedure to test an electronic EGR is a bit different and requires a multimeter. If you notice your vehicle running poorly, stalling or having poor gas mileage, you should test the EGR.
What happens if you open the EGR at idle?
Opening the EGR at idle should stall the car. If the car doesn’t stall, assuming the bench test was successful, there’s something stopping the flow of the EGR.

How can I tell if my EGR is bad?
Turn the ignition key to the “On” position. Read the multimeter. If the volts measure above 0.9 then the system should be serviced. If there is no voltage, the EGR is bad and should be replaced.
