So I have a 05 Honda Accord coupe with the 2.4L auto. I did a cai on it and it didn't run right so put stock back on. It threw a few codes for the 02 sensor. So I replaced BOTH sensors and used a code scanner to erase the codes. Light did come back on and here's the list of codes:
61-1
P0138 (temp 63-19
​​​​P2271 (current 63-17)

I did both correctly and with no issues so what the hell is the issue? The engine light is keeping my cruise from activating.

PLEASE HELP!

Not sure if you plug battery before installing cai. I did with my mustang, unplug battery, install cai, plug back and no error code. Try unplug/plug back battery maybe that will work.
