Diagnostic Aids

WARNING: This page is about a different car, the 2002 Isuzu Rodeo Sport and 2002 Isuzu Rodeo. However, it is still accessible from the selected car via links, so may be relevant.

Check for faulty connections or damaged harness. Check for poor connection at PCM. Inspect harness connectors for backed-out terminals, improper mating, broken locks, improperly formed or damaged terminals and poor terminal connection. If connections and harness appear okay, observe Bank 1 HO2S-1 display on scan tool while moving all related harnesses and connectors. A change in scan tool display indicates fault location. If DTC cannot be duplicated, FAILURE RECORDS data can be used in determining vehicle mileage since DTC was last set.
