Hey everyone. This morning my CEL came on and it pulled code:
P20EE
NOx Catalyst Effieciency Below Threshold
DTC severity 3 of 3: Stop and repair vehicle immediately

My shop can't get me in for a couple weeks and I need to be on the road a bunch this month. Will my truck be fine to drive until I get it looked at? At the auto parts store they looked up the code and said the part would be a NOx sensor. If that is emissions related, will that impact the drivability of my truck for a couple weeks?

P20EE won't damage anything (you can keep driving), it is related to the NOx/DEF system and likely is a sensor but your shop should do proper diags to make sure the issue is the sensor and not something else with the DEF system.

As for driving it for a couple of weeks, the only concern I'd have is if it will eventually tell you "X miles until speed limited" in which case if you keep driving until the countdown finishes then you'll be in limp mode.
