Diagnostic Aids

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. Inspect wiring harness for damage. Move connectors and wiring harnesses related to sensor display on scan tool. A change in display may indicate location of fault. If DTC cannot be duplicated, FAILURE RECORDS data can be used in determining vehicle mileage since DTC was last set.
