Check Engine light on 94 YJ

[Bouncyballs]

My check engine light comes on after i have driven about a mile, and i Tried the OBD ignition code thing, and the sequence was 1-2-3-3-2-1-5-5 so i didnt know what that ment. Just wondering if anyone else has had this problem, and what it might be.

thanks.

ok nevermind, i got the codes, and the 12 is the battery being disconnected, the 33 is an open or shorted condition detected to AC clutch relay circut.
and the 21 is my oxygen sensor has broken off, and is attached by the wires...

You can disregard the 33 if you have no AC, seems it's pretty common on non-AC rigs. Did you get the 21 fixed?
