Last night I drove the 04 since I was a gallon short of the required 12 quarts/3 gallons of oil the Cummins takes but didn't realize it until I was filling her. (Thank God for 24 Hour Walmarts!)

Anyway, I still haven't got around to having the valve stem installed that Titanequipped sent me to replace the one I snapped off so I'm driving with the spare on the front and for some reason I'm not getting an alarm?

I was under the impression that the spare didn't have a sensor and if this is true I would say I have a problem?
