Diagnostic Aids

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

Check front HO2S heater circuits for intermittent faults. If front HO2S heater circuits are okay, replace front HO2S. If DTC cannot be duplicated, check scan tool FAILURE RECORDS to determine mileage since last DTC was set.
