WARNING: This page is about a different car, the 2001 Mazda Protege, 2001 Mazda Millenia, 2001 Mazda MX-5 Miata, 2001 Mazda MPV, and 2001 Mazda 626. However, it is still accessible from the selected car via links, so may be relevant.
Remove EGR vacuum solenoid. See EGR VACUUM/VENT SOLENOID VALVE LOCATIONS table. Apply air pressure to a EGR vacuum solenoid valve port. See Figure . Air should not flow from other EGR vacuum solenoid port. Using fused jumper wire, apply battery voltage to EGR vacuum solenoid valve terminals. Air should flow with voltage applied. If EGR vacuum solenoid valve does not operate as specified, replace valve.
