I have the Flo Pro DPF delete and got the typical codes - P242B P1453 & P2453. lately I have also been getting P2000 - is this part of the delete issues or a REAL problem? What is P2000?

 

You have a converter right after the turbo called the NOx absorber. It does essentially that. The computer measures the amount of storage capacity of this converter. If it sees that it is not doing it's job appropriately, it will set this DTC. This doesn't always mean it is the cat though, it normally only means the upstream O2 sensor is clogged with soot and needs to be cleanes. There is a bulletin on this where you will get 2 brand new, updated sensors plus a section of your exhaust wrapped. This is taking care for the most part this code. Now lets just hope you didn't do something dumb like do your dpf delete while still under engine and emission warranty.

 

Long past warranty! I will try cleaning the sensors and see what happens.

 

P2000 is a normal code with the delete. After a year I still sometimes get that code. Not to worry it will affect nothing.
