What terminals are you measuring on the TPS? How did you have your meter connected?

 

[Dave A.]

What year is your MKII? Auto or manual trans.? The variable resistance type TPS was only used in 85 and 86. The others use the switch type TPS but there's a different one for the auto and manual trans.. The 85 & 86 use the same variable resistance type (round shaped) TPS for both transmissions.
