Throttle Position Sensor (TPS)
NOTE:
XT Coupe uses a single TPS sensor and switch. All other models use separate TPS and sensor throttle opening switches.
- Loosen mounting screws on XT Coupe sensor or TPS on all other models. Insert a .022" (.55 mm) feeler gauge between stopper and stopper screw. See Fig 1 or Fig 2 . Connect ohmmeter between terminals No. "3" and "4" on XT Coupe ("A" and "C" on all other models). Adjust sensor position so ohmmeter reads zero with feeler gauge in position.
- Insert a .036" (.92 mm) feeler gauge between stopper and stopper screw. Ohmmeter should read zero ohms. If not, adjust sensor position until proper readings are obtained. See Fig 2 .
- Remove connector from TPS on XT Coupe (3-terminal throttle opening switch on all other models). Check resistance between terminal wire colors. If resistance values are not as given in THROTTLE SWITCH RESISTANCE table, replace switch.
