maint. required light on: Code 33

Hello all loyal and helpful Jeepers,

My maintenance required light is on: I plugged a scanner tool in and it gave me the code 33. Which is something to do with the air conditioning clutch relay. I am confused by this and need help understanding what might/is wrong with the jeep. First, if this is an air conditioning related problem then I am seriously confused. The car does not have AC. Or, second, is it cooling process (for lack of a better term) for the clutch and the relay has shorted out?

As always, thanks for the help and advice. Be well and happy Jeeping,

The maintenance required light is a reminder light to replace the O2 sensor after a set amount of miles. On the older Jeeps it was run off a timer module, but i believe yours is new enough that it its controlled by the computer. Not sure, but i think it has to be reset with a scan tool, but only certain scan tools have the capability.
As far as the code for the ac relay, if you don't have ac, it'll throw a code for it. It's normal and nothing to worry about.
