Throttle Position Sensor: Turbo

  1. Disconnect electrical connector from Throttle Position (TP) sensor. Loosen TP sensor mounting screws. Connect ohmmeter between terminals IDL and E2 on TP sensor. See Fig 1.
  2. Apply vacuum to throttle opener. To set initial clearance, insert a .030" (.76 mm) feeler gauge between throttle stop screw and throttle lever. Gradually rotate TP sensor clockwise until ohmmeter deflects. Tighten TP sensor mounting screws. Remove feeler gauge.
  3. Insert a .027" (.69 mm) feeler gauge between throttle stop screw and throttle lever. Continuity should now exist between terminals IDL and E2 on TP sensor. Remove feeler gauge.
  4. Insert a .032" (.81 mm) feeler gauge between throttle stop screw and throttle lever. No continuity should now exist between terminals IDL and E2 on TP sensor. Remove feeler gauge. Disconnect ohmmeter. Install electrical connector on TP sensor.
