Diagnostic Aids

If CMP sensor circuitry is okay, check CMP sensor signal rotor for proper alignment or damage.

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.
