Title: excellent quality part
Product review: This sensor works exactly like the volume knob on your stereo, varying the resistance to tell the computer the position of the throttle (anywhere from full open to full closed).They are easy to test, just check the resistance with an analog meter between the black and green wires while opening and closing the throttle plate. If the needle does not give a nice smooth sweep, replace it.Made my truck run a whole lot better (my worn sensor was causing a high idle, lack of power, and bad timing), and was worth the extra money to not buy a cheap part (never ever buy cheap automtive electrical parts - I learned that the hard way). The part has gone up a whole lot more in price since I bought it, but that is not the part's fault.Because I know for a fact this is a good part, I still recommend paying the extra money for this despite the price increase.
