DriBone: the info the dealer told you doesn't contradict the info here. he said it varies between .5vdc and 5vdc, and thats correct. it would only be near 5vcd near full throttle. you must remember that the output voltage varies with the throttle position, that is what the guy at the dealer was hinting at.
what this thread is about is adjusting the position of the TPS so that the output voltage is exactly .98x when the throttle is at idle position. after you have adjusted it, the output voltage will vary between .98x volts and around 5 volts depending on throttle position.
if you removed the TPS completely then re-installed it, and the truck didn't run right after that, I'd imagine it's possible you re-installed it at a different position than it was in before, and the computer would not have a correct reading of how open the throttle was. the dealer probably diagnosed it as a malfunctioning TPS because it's not showing the reading it should, and they have no idea the TPS may have been rotated a bit :P
