The reason I did not replace was a right angle screwdriver was needed which I do have, but the screw was frozen and stripped. If the LS430 follows the same concept, but places the TPS at the pedal, then it would almost stand to reason that if pressing on it a few times does not work, and if it's not a software glitch, then the physical device needs to be replaced. But I think on the LS430 it's like 10X the cost of the Nissan....
