Inhibitor Switch (A/T)

Switch is located on transmission/transaxle. Switch notifies ECU when transmission/transaxle is in Park or Neutral and signals ECU 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.
