Diagnostic Aids

WARNING: This page is about a different car, the 2000 Isuzu Hombre. However, it is still accessible from the selected car via links, so may be relevant.

Due to moisture in exhaust system, EGR valve may sometimes freeze and stick in colder weather. Problem may disappear after vehicle is brought into a warm shop for repairs. By using scan tool and watching actual EGR and desired EGR positions on a cold engine, fault can be easily verified. Check FREEZE FRAME data to determine if DTC set when vehicle was cold by viewing ECT.
