P2043
I just replaced my reductant heater Unit last week and that removed the P205C code, I then took it to Ford to have PCM re-flashed to remove the P2043 code last Friday. I drove home and parked the truck until today and when I drove to the store and the CEL was back with the P2043 code again after the flash and less than 60 miles driven with 3-5 start cycles. I cleared code and contacted Ford which of course told me to bring it in for Diagnostics ( 199.00 per HR) if it came back on.

There solution is always bring it back no problem as long as u dont need your truck for work or like spending all your time dropping off trucks for service that was supposed to be fixed already...
