P21B0 CODE
So I have a 2016 F250 diesel with 40k miles, yesterday the CEL came on. Pulled the code P21B0 Reductant Level Sensor "C" Circuit high. So I did some online searching, turns out this has been an ongoing issue with Ford's DEF sensors since like 2012 with the 6.7's. WTH? You would of thought Ford would of fixed this problem by now. According to my emissions warranty, 5 years or 50,000, it should cover the repair through Ford. Can anyone attest to this or had a similar problem/ answer? Would appreciate any help on this issue. Thanks
