Error 31 "A/T FI Signal B"

Post by macloclen »

I've got a 90 Prelude 2.1SR and the engine light just came on while I was driving don't the highway. Car runs perfect as far as I can tell; light shouldn't be on.

Got the code from the ECU and it says error 31, A/T FI Signal B. Automatic Transmission B signal? Except my car is a 5-speed. What gives?

Can anyone give me some advice on this one?
