Diagnostic Aids

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

Check for poor connection, rubbed-through wire insulation or a broken wire inside insulation. Inspect harness connectors for backed-out terminals, improper mating, broken locks, improperly formed or damaged terminals, poor terminal-to-wire connection, and damaged harness. If harness appears to be okay, use scan tool to observe TPS2 display while moving connectors and harnesses. A change in display will indicate location of fault. If DTC P1220 cannot be duplicated, check scan tool FAILURE RECORDS to determine mileage since last DTC was set.
