TPS on 12A

Hey guys, simple question: what does the TPS do on a stock 12A nikki?

And yes, the Nikki carb does have a TPS. I’m thinking it controls the emissions system but not very confident about that.

Emissions system. Tells the "ECU" when to pump air into the exhaust manifold, exhaust ports, vent, cut ignition, etc.

There is a pretty good explanation in the 1st gen FSM.

The Factory Service Manuals for all years of RX-7 (and many other rotary cars) can be downloaded for free here: Foxed.ca - Mazda RX-7 Manuals . They contain all common service information and more, and are an essential tool for any sort of service work that needs to be performed on these cars.

Sorry to bump an old thread, but does the TPS on an automatic 12a rx7 have any part in the transmission kickdown functionality?
