Turn ignition off. Disconnect EGR Vacuum Regulator (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 - B2300, B2500, B3000, B4000 & TRIBUTE article.
