Throttle Position Sensor/Switch: Festiva

Ensure idle speed and ignition timing are adjusted to specification. Stop engine. Disconnect negative battery cable.
CAUTION: DO NOT tamper with throttle stop screw at throttle lever. Doing so may result in damage to throttle body.
Unplug Throttle Position (TP) switch connector at throttle body. Insert appropriate feeler gauge between throttle stop screw and stop lever. Check for continuity between specified terminals on TP switch connector. See THROTTLE POSITION SWITCH ADJUSTMENT (FESTIVA) table.
To adjust, loosen TP switch attaching screws. Connect ohmmeter between terminals IDL and TL. See Fig 1 . Insert a .020" (.5 mm) feeler gauge between throttle stop screw and stop lever.
Rotate TP switch until ohmmeter indicates continuity. Insert a .028" (.7 mm) thickness gauge between stop screw and stop lever. Ohmmeter should indicate no continuity. If ohmmeter indicates continuity, repeat adjustment procedure.
