HELP! liberty will not code pO837

jeep drove fine all day. It will not start back up. Sensory Key light on the dash is on again.

I have had this jeep five years never had a problem. I have had my ignition change out and new key programmed. I have had new PCM put in. It drives for about three days before the problem happens. The truck just turns over. Probaly tomorrow It will start up. I was wondering does anyone know what else will cause the sensory key light to come on if it's not the key? Any sensors or anything that could be going bad? I did just check. I got code PO837 . Could someone tell me what the code is and if it would cause the sensory key light to come on?

Please help

Not sure about the sentry key Illum. but a search of the innerweb gave me some info regarding the transfer case position sensor. Try finding the connector on that sensor and make sure it is connected and making good clean contact.

I took he battery cables off for about 4hrs...put them back it's starting up. It will go dead sometimes..but at least i made it back to my driveway...could the Crank or cam shaft sensor make it do that? i let it run for about 1hr. it cranks back up and runs...but i don't think the problem is fixed. it's been doing that for about three weeks...if i drive it somewhere it will die on me or not crank!
