My Honda Prelude SH has the ATTS light glowing with the engine check light. I went into autozone to see if they could check the engine light and they told me it was an O2 sensor. I changed the one they told me, then reset the computer and the problem came back. Went back again and they told me it was the other O2 sensor. So I changed that one as well, then reset the computer and the problem is still with me. I don't know what the problem is, maybe because the sensors are not real OEM ones they are the universal type from Autozone. And still don't know nothing about the ATTS light because they come on together. When I try to reset the computer.
Thanks for reading my problem.
