2. Connect the HDS scanner and turn the ignition switch ON. From the Menu, select "Transaxle", "Codes and Data Menu" and "Data" screen, go to "IDLE SW".





3. Place a 0.65 mm (0.025 in) thick feeler gauge between the fixed Speed Adjusting Screw (SAS) and throttle lever.





4. Loosen the TPS mounting bolts and turn the TPS body fully counterclockwise. Confirm that the idle switch readout shows "CLSD".

5. Slowly turn the TPS body clockwise until the idle switch readout shows "OPEN". Tighten the TPS mounting bolts securely.

6. Remove the feeler gauge.

7. Confirm that the idle switch changes from "CLSD" at idle to "OPEN" as the throttle is slightly opened.

8. Check the TPS output voltage.

STANDARD VALUE: 0.4-1.0 V

Note:
If the voltage is out of the specification, check the TPS and associated harnesses for damage. Replace TPS and associated harnesses if necessary.
