Throttle Position Sensor: Adjustments

THROTTLE POSITION SENSOR INSPECTION/ADJUSTMENT PROCEDURE

1. Inspect throttle position sensor.
(a) Apply vacuum to the throttle opener.
(b) Insert a feeler gauge between the throttle stop screw and stop lever.

Ohmmeter Connection:

Reference:

(c) Using an ohmmeter. measure the resistance between each terminal.





2. If necessary, adjust throttle position sensor
(a) Loosen the 2 set screws of the TP sensor.
(b) Apply vacuum to the throttle opener.
(c) Insert a 0.62 mm (0.024 in.) feeler gauge between the throttle stop screw and stop lever.





(d) Connect the test probe of an ohmmeter to the terminals IDL and E2 of the TP sensor.





(e) Gradually turn the TP sensor clockwise until the ohmmeter deflects, and secure it with the 2 set screws.
