Throttle Position (TP) Sensor Continuity: Adjustment

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 -Fig 3 . Insert a feeler gauge of specified thickness between throttle lever and throttle stop screw. See TP SENSOR CONTINUITY (MILLENIA, MPV & 626 2.5L) .
Loosen TP sensor screws. Rotate TP sensor until ohmmeter indicates continuity as specified. See TP SENSOR CONTINUITY (MILLENIA, MPV & 626 2.5L) . 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.
