I have a 93 Honda Civic HB with a D16 engine swap from a 95 Civic Si. The engine light came on after the swap, and I thought it was the O2 sensor gone bad. So I changed that, and its still on. Is there anything else i can check that would make the light go off? I tried disconnecting the battery too, but still no luck. I thought for sure it was the O2 sensor. It even drives better after I changed it. Thanks guys.

why don't you just get the code and save yourself the headache of trying to figure out what it is.

where or how would I do that? I know very little so far about hondas. They're fun though..

Go autozone or pep boys and have them read the codes for you it should be free.

thanks man... never would have guessed...

jump the wires. theres plenty of threads concerning it. search and you shall find ;)

That was so much easier than i thought it would be. It's a code 19=automatic transmission lockup control valve. I have a 95 civic si engine in a 93 Civic HB, and the engine was a auto, and my HB is a manual. What can I do to fix this. I'm just glad there's nothing really wrong, just want that darn light off..
