Throttle Position Sensor: Adjustments

Tool Required:
J 39200 Digital Multimeter

Description:

1. Connect a DMM (J 39200) to the TP sensor terminal 1 to 2 (TP sensor side).
2. Measure the resistance.


Important: The throttle valve must be closed.

Description:

3. Insert a 0.65 mm (0.026-inch) feeler gauge between the throttle stop screw and the throttle lever.
4. With the retaining screws loosely installed, turn the TP sensor fully counterclockwise.
5. Gradually turn the TP sensor clockwise in order to find the position where the ohmmeter reading changes from continuity to no continuity. Tighten the TP sensor bolts to 2.5-4.5 Nm (22.8-38.4 lb. in.).

6. Remove the feeler gauge. The DMM should still indicate continuity.

Description:

7. Insert the 0.8 mm (0.037-inch) feeler gauge between the throttle stop screw and the throttle lever. The DMM should now indicate an open circuit (no continuity).
