Error codes on a YJ

[Lights Squared]

Hello everyone!

I have some questions on error codes on my 1992 Yj. I counted the error codes 5 times to make sure I recorded the error codes correctly. Here are the codes that my Yj is giving me:
12- I can't find a #12 error code in the manual. The manual starts @ error code 11 and then jumps to error code 13. Can anyone tell me what a # 12 error code is?

33- Air conditioning Clutch relay....... the vehicle does not have or has ever had A/C. Not sure how to fix this one. Any Ideas??????

I need to repair before it will pass smog.

Thanks,
Tim

The list I have shows 12 as "Problem with battery connection.Direct battery input to controller disconnected within the last 50 ignition key ons."
I'd say verify your battery connections & grounds...a faulty connection could be causing the bogus 33 too.

Thx TLCJ5! I'll take a look at the battery connection.
I'll keep you posted as to the out come.
Take care,

TLCJ5, you were correct, after I replaced the 02 sensor and changed all the battery connections....................no error codes!

Thanks
