Hey guys, I'm about 1200 km's from home right now and 4 hours to the nearest dealership and my truck has a few codes up. The truck is not deleted, all stock except for AFE intake that's been 20,000 km's with zero issues. 36,000 km's total.

P2BAC - NOx exceedence, EGR Disabled
P0141 - Heater O2 circuit bank 1, sensor 2

The truck is still running but keeps throwing the same codes if I clear them. Feels like its lost power, no smoke or noticeable noises under the hood. Any help would be appreciated, is it going to hurt anything to run it like this for 2 more weeks until I make it back home?

 

According to the manual I have:

P2BAC is an information only DTC and indicates an engine power derate has been implemented. Repair all other active DTCs present and this DTC will become inactive.

P0141 - this is setting the above code - once fixed your problems should go away.

Check all connectors related to the O2 sensor to make sure nothing got jarred, frayed, or torn.
