Throttle Position Sensor (TPS)
NOTE:
Vehicles with Electronically Controlled Transaxle (ECT) use signals sent from TPS to Electronic Control Unit (ECU) to calculate gear shift and lock-up timing.
- Loosen mounting screws. Unplug TPS connector. Connect ohmmeter between terminals IDL and E2. See Fig 1-Fig 3 .
- To set initial clearance, insert proper thickness feeler gauge between throttle stop screw and throttle lever. Refer to the THROTTLE POSITION SENSOR ADJUSTMENT table.
- With ohmmeter showing infinity, rotate TPS clockwise until continuity exists. Tighten mounting screws. Using specified feeler gauge, recheck adjusted clearance. Disconnect ohmmeter and reconnect TPS after adjustment.
