Diagnostic Aids

Check for a faulty cruise control module, if equipped. Cruise control malfunction that causes VSS signal to be pulled low may cause DTC P0500 to set.

An intermittent malfunction may be caused by a poor connection, rubbed-through wire insulation, or a wire broken inside insulation. Inspect harness connectors for backed-out terminals, improper mating, broken locks, improperly formed or damaged terminals, or poor terminal-to-wire connections before component replacement.
