P20BE and P20BD codes

Check engine light came on yesterday, after scanning the following codes came up, (P20BE and P20BD) after googling around I found that it’s DEF related something to do with the heater. Can I still drive while I have these codes?
The weather here has been very wild going from -35c to 0c in a matter of days, Today it’s -10c. I’m also curious if this rapid change in temperature could attribute to this error code. Should I clear the codes and see if they come back up?
Thanks everyone.

Edit: cleared the codes myself and the engine light turned off, still has permanent codes when scanning, when I started the truck after it turned over a few times and sputtered alittle but started. I have the block heater plugged in so that was weird, turned it off and then started it again with no delay that time.
