  1. Loosen throttle position sensor mounting screws. Insert a .022" (.55 mm) feeler gauge between stopper and stopper screw. See Fig 1 . Connect ohmmeter between terminals "A" and "C". Adjust sensor position so ohmmeter reading changes from zero to infinity with feeler gauge in position.
  2. Insert a .036" (.92 mm) feeler gauge between stopper and stopper screw. Ohmmeter should read zero ohms. If not, adjust sensor position until proper readings are obtained.
