p202e code

[Bellalirah]

hello i am Hannah, new to the group, and hava 3500 4wd diesel turbo 6.7 and a code p202e came up and the tech said as long as my def was full and does not freeze that i do not have to worry about anyhting.. well i live in texas and it does not freeze hard enough for def to freeze..( i think) so do i need to fix the error code / message or just do what the tech said and continue to drive as normal

Some codes will clear themselves based upon multiple successful ignition cycles. Diagnostic events have a counter that increments or decrements in the SW. So this will likely clear after some amount of time.

If the truck is under warranty the dealership will clear it for free.
