EGR Vacuum Regulator (EVR) Solenoid

Turn ignition off. Disconnect EVR solenoid wiring harness connector. Measure resistance between EVR solenoid terminals. If resistance is not 26-40 ohms, replace EVR solenoid. For additional EGR system testing, go to TEST HE under SYSTEM TESTS in SELF-DIAGNOSTICS - EEC-V (GASOLINE) article.
