▶ Many malfunctions in the electrical system are caused by poor harness(es) and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage. So, check poor connections and the related circuit between ECM/PCM and component thoroughly. Repair as necessary and go to "Verification of Vehicle Repair" procedure.

▶ Substitute with a known - good FPS and check for proper operation.
