Have recently completed some research on alternative TPS & have ascertained that a very likely option is perhaps a Standard TH198 & equivalents which are Wells TPS246, Motorcraft CX1528, Tomco 14042, Walker 200-164. Its a very common TPS fitted to many USA Ford models.
It appears the drive pegs are in the same position as the Jag part which is JLM12074 or Standard TH417. I assume both it & the Jag part turns clockwise & that voltage range is very similar (0.6v idle to 4.9v full throttle)
Perhaps other members may have done further research & add to this quest for an alternative replacement to this costly Jag part.

 

This would be great news, especially if the TPS is much cheaper.

I have a TB I'd like to get a TPS for as it didn't come with one.

Has anyone tested?

Couple years ago I researched the Ford Scorpion as an option for the TPS(see thread below). I found the Ford rotated in the wrong direction. Hope this helps. Please keep us informed as to new results.

Hi did you ever get any further with the identification of a suitable aftermarket TPS ?
