Throttle Position (TP) Sensor

NOTE: Vehicles with Traction Control System (TRAC) are equipped with a main TP sensor and a sub-TP sensor. The following procedure applies to main TP sensor. For sub-TP sensor, see SUB-THROTTLE POSITION (SUB-TP) SENSOR .

Disconnect TP sensor connector. Measure resistance across specified terminals of TP sensor connector. See TP SENSOR RESISTANCE table. See Figure. If resistance is not as specified, adjust TP sensor . See THROTTLE POSITION (TP) SENSOR in ADJUSTMENTS article. Recheck resistance. If resistance is still not as specified, replace TP sensor.
