P20EE

[leadfootexp]

So, looking for any help on this. Have the P20EE code. Taken it to the stealership for the fifth time now, switch dealers in between. They've flasked the PCM three times, replaced the CAT, and replaced the NOX sensor. Any other ideas as i'm tired of the dealership runaround?

Delete it and never look back

How many miles on the truck? If you don’t want to delete it, look into lemon law in your state. If you’re willing to delete, like the user above said, delete and never look back. I Have a 2012 with 230k miles deleted. Literally, not a single drivetrain issue. 68rfe all original too.
Ordered a 22 and will try to keep it stock but if it gives me issues and gets me stranded somewhere on the interstate (I travel a lot), I’ll delete it in a heartbeat.
Good luck and please update us on what they find if they figure it out.

Just rolled over 60,000. It's a 2019. Seems like they're programmed to throw a code every 20,000 miles.

Been fighting for another 20,000 miles. Replaced the cat again under warranty, Nox sensor and new doser. Def checks out good as I have a fleet and none of the other vehicles have after treatment issues, just my personal 2019 Limited.
