DEF Tank Replacement for 1 Sensor???

[txonmymind]

The root cause was the sensor that is built into the tank. My code was P207F. The good dealer that finally fixed my truck actually checked that my DEF was correct quality, then they tested the injector, and then they finally determined if those two were good then the sensor in the tank is giving incorrect signal. Your "no DEF flow" code make me think you have a faulty pump. There might be a way to test the pump using Alfaobd but I have never even tried to plug Alfaobd into my truck so I have zero knowledge whether it can be tested on there.

Thanks for the answer. If I have to take it back to the dealer I want to put them on the right track and hopefully not waste time since there's been a lot of replacing parts only for another code to pop. Didn't have it for four months, very frustrating.

Googling your code seems to indicate just a pump replacement needed. If I am not mistake the pump drops right out the tank. Might be easy enough to replace yourself if you can get the parts.
