1999 Prelude SH
The check engine light came on recently along with the ATTS light. I took it to auto zone to see if they could tell me why the check engine light in on but they could not find the terminal for the computer any idea where that would be? Im thinking its on because of the ATTS. Would anyone know what it usually consists of when having problems with ATTS?
Thanks

I wrote up a quick how to on how to get the check engine light code here:

You may have a problem with ATTS. Start by getting the codes, and we'll go from there.

Thanks that helped out you would never think to look there. The code is what should be 65 it blinked 6-slow times and 5-short times and then repeated. Did not see 65 on the list of codes. can you help?

Found out that 65 is "Secondary Heated Oxygen Circuit". Check your oxygen sensore wiring and the sensors themselves.
