WARNING: This page is about a different car, the 2000 Mazda Protege, 2000 Mazda Millenia, 2000 Mazda MX-5 Miata, 2000 Mazda MPV, and 2000 Mazda 626. However, it is still accessible from the selected car via links, so may be relevant.
EGR position sensor is part of EGR valve. Disconnect EGR position sensor connector. Disconnect vacuum hose from EGR control valve. Measure resistance between EGR position sensor terminals. See EGR POSITION SENSOR RESISTANCE table. See Fig 1 . Apply 5.9 in. Hg of vacuum to EGR position sensor and recheck resistance. If resistance is not as specified, replace EGR valve.
