Throttle Position (TP) Sensor Continuity: Adjustment

WARNING: This page is about a different car, the 1997 Mazda Millenia. However, it is still accessible from the selected car via links, so may be relevant.

Turn ignition off. Ensure throttle valve is in closed position. Disconnect TP sensor connector. Connect ohmmeter between terminals "C" and "D" of TP sensor connector. See Fig 1 . Insert a feeler gauge of specified thickness between throttle lever and throttle stop screw. See TP SENSOR CONTINUITY table.
Loosen TP sensor screws. Rotate TP sensor until ohmmeter indicates continuity as specified. See TP SENSOR CONTINUITY table. Tighten TP sensor screws. Open throttle valve fully a few times. Recheck TP sensor adjustment. If TP sensor is not adjusted as specified, replace TP sensor.
