Throttle Position Sensor: Adjustments

1. Disconnect battery negative cable, remove air cleaner assembly and disconnect TPS coupler.

Inserting Thickness Gauge:

2. Insert 0.6 mm (0.024 in) thickness gauge between throttle stop screw and throttle lever.

3. Loosen TPS screws.

Adjusting Throttle Position Sensor:

4. Connect ohmmeter between A and B terminals.

5. First, turn TPS counterclockwise fully and then clockwise gradually to find position where ohmmeter reading changes from 0 (zero, continuity) to (no continuity). Then fix TPS at that position by tightening screws to specified torque.

TORQUE VALUE
1.5 - 2.4 Nm (0.15 - 0.24 kg/m, 1.2 - 1.7 lb-ft)

6. Check that there is no continuity between terminals A and B when 0.9 mm (0.035 in) thickness gauge is inserted.

7. Check that there is continuity between terminals A and B when 0.3 mm (0.012 in) thickness gauge is inserted.


If check result is unsatisfactory in steps 6 and 7, it means that installation angle of TPS is not adjusted properly. Therefore, start all over again from step 1.


CAUTION: As throttle stop screw is factory adjusted precisely, never adjust it.

8. Connect coupler to TPS securely, install air cleaner assembly and connect battery negative cable.
