I'm catching up with some car maintenace this weekend and yesterday the ECU threw a CE light. Working from (flawed) memory I pulled codes from the A 6 port and got a I-II-II which I reset. I still had the CEL so cracked a book and found I needed to check port A 2. I had a II-III-II (lean or rich at idle) which I can find and fix.

Qustion is, what system does the A 6 port report from and what was the I-II-II code I found there?

Thanks,
ENR
