      Comments about BWD Throttle Position Sensor:

      After removing air intake was easier to get to the holding screws. Use a square shafted screw driver and a wrench to turn out the original screws they seemed Lock Tighted in. Once broke loose the rest was easy. Note: didn't fix the low idle problem.....

          The throttle position sensor measures and reports the amount of throttle opening to the engine control computer. The computer uses this information to make adjustments to the mixture of fuel and air used for combustion.

          This sensor sends a signal to the engine computer to tell it how open or closed the throttle plate is.
