Throttle Position Sensor

Disconnect electrical connector from Throttle Position (TP) sensor. Loosen TP sensor mounting screws. Connect ohmmeter between terminals IDL and E2. See Fig 1.
Apply vacuum to throttle opener (if equipped). To set initial clearance, insert proper thickness feeler gauge between throttle stop screw and throttle lever. See THROTTLE POSITION SENSOR ADJUSTMENT table.
Gradually rotate TP sensor clockwise until ohmmeter deflects. Tighten TP sensor mounting screws. Using specified feeler gauge, recheck for continuity and no continuity at adjusted clearances. Disconnect ohmmeter. Install electrical connector on TP sensor.
