Sub-Throttle Position (Sub-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 sub-TP sensor. For main TP sensor, see THROTTLE POSITION (TP) SENSOR .
Disconnect sub-TP sensor connector. Measure resistance across specified terminals of sub-TP sensor connector. See SUB-TP SENSOR RESISTANCE table. See Figure. If resistance is not as specified, adjust sub-TP sensor. See SUB-THROTTLE POSITION (SUB-TP) SENSOR in ADJUSTMENTS article in the ENGINE PERFORMANCE section. Recheck resistance. If resistance is still not as specified, replace sub-TP sensor.
