What's inside the 4AGE 16V TPS ??

This is a question that I'm sure many people have asked themselves. But not
having a spare TPS to pull apart, most are destined to live out their lives without
ever achieving black-belt level in TPS knowledge. Never fear... help is at hand
This is the throttlebody side of the TPS... what you see when you take it off.
This is the other side with the plastic cover removed.
The metal "wipers" that rotate with the throttle and run on the carbon tracks.
And the carbon tracks that complete the circuits and provide resistance.
This particular TPS (89452-12050) came from an AE82 if I remember correctly, but
it is of the same era as the AW11 and AE86, so should be near enough the same. It
is not designed to be opened so therefore should be considered non-repairable. The
clips that hold the back cover on have to be broken to get the cover off. Under the
cover is a thin rubber diaphragm/sealing gasket, and below that the white board for
the carbon tracks. The board is gripped by clips that are part of the TPS output pins.
