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 Fig 1. If resistance is not as specified, adjust TP sensor. See THROTTLE POSITION (TP) SENSOR in ADJUSTMENTS article in this section. Recheck resistance. If resistance is still not as specified, replace TP sensor.

⁽¹⁾	Disconnect vacuum hose from throttle opener. Apply vacuum to throttle opener to allow throttle to fully seat.

⁽²⁾	Insert feeler gauge between throttle lever and throttle stop screw.

⁽³⁾	SC300, insert a .024" (.60 mm) feeler gauge between throttle lever and throttle stop screw.
