Throttle Position Sensor


THROTTLE POSITION SENSOR INSPECTION

1. Inspect throttle position sensor
(a) Insert a 0.40 mm (0.016 in.) or 0.65 mm (0.026 in.) feeler gauge between the throttle stop screw and stop lever.

Ohmmeter Connection:




Reference:





(b) Using an ohmmeter, measure the resistance between each terminal.
2. If necessary, adjust throttle position sensor





(a) Loosen the 2 set screws of the sensor.
(b) Insert a 0.40 mm (0.016 in.) feeler gauge between the throttle stop screw and stop lever.





(c) Connect the tester probe of an ohmmeter to terminals IDL1 and E2 of the sensor.





(d) Gradually turn the sensor clockwise until the ohm meter deflects and secure it with the 2 set screws.

Ohmmeter Connection:




Reference:





(e) Recheck the continuity between terminals IDL1 and E2.
