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 gas cap, vacuum canister and EVAP hoses, lines and EVAP components for damage. Check for faulty connections or damaged harness. Observe EVAP system components displayed on scan tool while moving all related harnesses and connectors. A change in scan tool display indicates fault location. If DTC cannot be duplicated, check scan tool FAILURE RECORDS and FREEZE FRAME data to determine mileage since last DTC was set.
