Throttle Position (TP) Sensor: Adjustment

WARNING: This page is about a different car, the 1994 Mazda MX-6 and 1994 Mazda 626. However, it is still accessible from the selected car via links, so may be relevant.

Disconnect TP sensor connector. Connect ohmmeter between TP sensor connector terminals "E" and IDL. See Fig 1 . Loosen TP sensor attaching screws.
Insert a .006" (.15 mm) feeler gauge between throttle lever and throttle stop screw. Rotate TP sensor clockwise about 30 degrees, then rotate counterclockwise until ohmmeter indicates continuity.
Remove feeler gauge. Insert a .020" (.50 mm) feeler gauge between throttle lever and throttle stop screw. If ohmmeter indicates no continuity, go to next step. If ohmmeter indicates continuity, repeat adjustment procedure.
Tighten TP sensor attaching screws. Open throttle valve fully and verify resistance between terminals "E" and Vt is about 5000 ohms.

NOTE: TP sensor on MX-6 2.0L and 626 2.0L is not adjustable.
