O(2) Sensor Engine Codes

[TEX_03]

My family has a 2010 Dodge Ram 2500 producing the following codes:

P0037 O2 SENSOR 1/2 HEATER CIRCUIT LOW
P0137 O2 SENSOR 1/2 CIRCUIT LOW
P0036 O2 SENSOR 1/2 HEATER CIRCUIT OPEN
P0138 O2 SENSOR 1/2 CIRCUIT HIGH

according to my Automatic App (v2.4.1).

My sister has been starting the truck a couple of times a week to idle to charge the batteries, though I am thinking that's a bad idea not to get to temperature since the weather has turned cold (here in Michigan).

I am a novice when it comes to mechanical stuffs, is there anything to try out before taking the truck into the dealer?

Thanks,

Michael

There is a tsb to assist this issue on 10-12 my trucks-not really a diy job for most.Tsb 25-002-14

Possibly the wire harness to the O2 sensors needs to be replaced. TSB as mentioned above. I had an extended warranty which covered the repair, less my deductible. Other posts have stated a repair cost estimate of roughly $450.00 without warranty. Not sure if it would be covered under emissions warranty, which is 5yr/50k miles.
