System Check - Protege

Disconnect negative battery cable. Inspect EGR valve system vacuum hoses for improper routing, kinks or leaks. Using ohmmeter, measure resistance between EGR valve terminals "C" and "E", "C" and "A", "D" and "B" and between "D" and "F". See Figure . Resistance reading should be 20-24 ohms. If resistance readings are not as specified, replace EGR valve. If readings are as specified, check wire harness between EGR valve and PCM for short or open circuit. See WIRING DIAGRAMS article. Repair as necessary.
