P207F Error Code

[Steve Edwards]

I have a 2013 6.7 Super Duty. I was shopping today, got back in truck, started it, and notice an “engine” light on. I had no other errors or alarms. Nothing was coming up concerning DEF.
I checked error code, and it was P207F. Looking online concerning that code, and it was always related to either DEF, or reduction in power, etc. I have none of those warnings or issues. It runs fine, even with the error showing. I was able to clear it and drive about 10 miles with it cleared, but now engine light just comes back on.
I have 113,000 miles on the truck.
I pray there is nothing expensive going on. Any suggestions or help would be appreciated.

Anytime you have a code you need to know, just Google it. Nox sensor.

I’ve had that a couple of times. Once it was the exhaust temp sensor that went out. Roughly $100 to change. The other time it was the heater in the def that was going out. Not fun to change that one.

I have 2011with the code P20BA it is the DEF heater I am bringing it in to shop Wednesday the quote I got is 770 bucks done parts and labor
the truck has 61,000 miles so it looks like you got twice as much work out of yours.Good luck hope this helps,,
BTW,,,if you YouTube the code it will come back and show you pretty much everything you need to know
