Here is a link to a discussion for the XJS 5.3 V12 TPS.
From that discussion and my measurements:
“My new question is that the book says “same resistance as the original at both ends of its travel (from .05 to 3.5K ohms)”, yet mine reads reads 4.7 to 5.0k ohms at spring stop idle position, and .25 to .30k ohms (250-300 ohms) at full WOT position (showing some of the inconsistent readings).”
I ordered the Ford TPS part number, E7DF-9B989-AA, for a backuo in case I need to use that instead.
