Inhibitor Switch (A/T Models)

Switch is located on transmission/transaxle. Switch notifies ECM when transmission/transaxle is in Park or Neutral and signals ECM of increased engine load when vehicle is in gear. This signal is used to calculate required changes in idle speed, ignition timing and injector operation.
