P1660 Acura - 1997 integra Ls

Question

I have a 1997 acura integra Ls 1.8L non Vtec And I just got P1660 code. My generic code manual said A/T FI signal A circuit failure. But I dont understand what that means or how to fix that. need help to figure this out.

Answer 1

P1660 Problem in the A / T FI data line

This is a communication failure , betweent the ECM (engine control module) and the TCM (transmission control module)

This can be from the harness from the ECM to the TCM, the easiaest way to resolve this is use a subsitute or known working ECM or TCM, Use a subsitute ECM ,clear the code if the problem goes away replace the original ECM if it does not try a subsitute TCM.
