    im also interested in this topic. as i was throwing a code for it, however after resetting the ecu it has not come back on. it only came on after i let off the gas after flooring it in second all the way to red line. 7800 rpm, i have a F20B. i guess what im asking is what does that sensor do? i mean the throttle is controled by a cable, so what is it sensing? how open or closed it is and i guess allowing some fuel changes and stuff like that?

      I had a tps go bad, when trying to tune my car on the dyno we could watch the % open work perfect till about 90% then it would fall back all the way to a -% while it should have read 100%. Was a huge issue trying to tune till we found that problem and fixed it. You can test the sensor with a voltmeter.

      I never looked into it further though.

          the tps is a rotary potentiometer, it reads how far the throttle plate opens and sends a voltage to the ecu, you can test it with a voltmeter. should read around .5 volt closed and 4.5v wide open(not sure about the exact volts, just google or look in a manual)

              it will make your car run like crap basically, when i put my motor in O'rielys sold me a bad tps and i kept throwing the code. the car literally wouldn't idle by itself, when i would drive it would just sputter around in limp mode basically


              If at first you don't suceed, then skydiving is not for you.

              I try not to down talk anyone, when I read my old questions I realize I was an idiot too.

                just replace it, your car will run very rich(limp mode) you will make the difference in gas in a week or 2 depending on how much driving you do.
