Throttle Position Sensor: Adjustments

1. Insert 3.5 mm (0.14 in.) thickness gauge between throttle stop screw and throttle lever.

CAUTION: As throttle stop screw is factory adjusted precisely, don't remove or adjust it.






2. Check to make sure that plunger of ISC actuator and throttle lever screw are not in contact with each other. If they are, warm up engine.
3. Loosen TP sensor screws.





4. Remove ECM as previously outlined and with couplers connected to ECM, connect digital type voltmeter as shown.
5. Turn TP sensor clockwise or counterclockwise and tighten TP sensor screw at a position where voltage as specified below is obtained at coupler terminal B11.

NOTE: If tech 1 and cartridge are available, it is not necessary to remove ECM. Make an adjustment by using tech 1 while observing TP sensor voltage.

TP sensor voltage when lever-to-stop screw clearance 3.5 mm (0.14 in.) : 0.98 - 1.02V
Tightening Torque: (a): 1.6 - 2.4 N.m (0.16 - 0.24kg - m, 1.2 - 1.7 lb - ft)
6. Install ECM and connect couplers securely.
