Default CAI and the O2 sencor?

Alright.

I have my CAI in place, but there is no prevision for the air flow sencor.
If I unhook it, the Batt and Engine light come on.
If I hook it up, and leave it under the hood, just the engine light comes on.

How can I get around this problem??

Anyone know any good diy tips to get around this?

Is there a way to bypass it so the engine warning light doesnt come on??
Im guessing its just a check between there and the one on the throttle body, to warn of a possible clogged air filter?

ideas? because driving with the EW light on is a little irritating.......

Dunno, not got that far yet.
Ill drill a hole and insert the sencor when I get home and go from there.

If the EW stays on, Ill do the keyturn x3 trick and see what error code I get.

Thanks for the info.
Ill have to remeber that, "Air temp"

Done.

It worked fine.
I made an adjustment, reattached the stock 90' with the hole and gromit for the O2 sencor.
Turned the engine over, and hoorah, the engine warning light went off.
