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 table applies to main TP sensor. For sub-TP sensor table, see SUB-THROTTLE POSITION (SUB-TP) SENSOR.

NOTE: If TP sensor resistance is not as specified, refer to the TP SENSOR ADJUSTMENT table.
