Hey Guys looking for some information on the difference between TPS's. I have 2 different ones I have mounted to custom TB's and they were both different. Different rotation/mounting position between the two. The one I currently have has irratic readings on my S-AFC and it idles irratically like a bad TPS. So what were all the different TPS's? Was there a difference between pre-89 and 89+? Or just a difference between turbo and NA? O the car is a 92' Turbo.

Also I am looking for a new TPS obviously if anyone has one in good working condition.

Thanks,
Seth

While there are only 2 different types of TPS used on the MA70, they were not always the same between N/A and GTE, and they did not change for the 89 model.

89452-28030 = 86.5 - early 87 7M-GE and 87 - early 89 7M-GTE (Replaced by 89452-20050)
89452-14050 = late 87 - 92 7M-GE and late 89 - 92 7M-GTE

The changeover for the 7M-GE was 11/86, for the 7M-GTE it was 03/89.
