I have a 1992 honda accord automatic with transmission problems. I swithced out the tcm, no fix checked solenoids (all clicking). I am getting a cel code of 30 and 31. I have the description for theses codes (below), but I do not understand what this means. Please help.

Thanks,

CEL Code 30 and 31 description:
A/T FI Signal A Low Input
A/T FI Signal A High Input
A/T FI Signal B Low Input
A/T FI Signal B High Input

 

I don't see a code 30 or 31. What light is flashing the code (check engine, D4, or S light)?

 

it is the check engine light. here is a link with codes
90-93 accord and obd1 cel codes.... - Honda-Tech

look at cel code 30 and 31.

thanks,

 

I misread your post. Those are check engine light codes.

Looking at the diagnostic tree, there are some electrical tests you can try. The tree ends with either fixing a wire or replacing the ECU. It will probably end up being the ECU (not the TCU).

Google 62sn700 pdf

That is a manual in pdf form for a non-us (I think) 1993 accord. It should be pretty close for troubleshooting to see which wires to test, etc..

 

Thanks. How do i get this manual 62sn700?

I am not too good with computers. Do I type this into a google search?

 

Here is a link to the file.
