Hoping it’s a fluke but just filled my truck and as I started it back up got my first CEL at 56k miles. P225D, NOx Sensor 1/1 Performance - Signal Stuck Low.

Hoping it’s a fluke. Truck was low on fuel, light was not on with ~90miles left on range. Filled it with 28.8 gal and covered 727miles of easy driving on the tank (no towing).

Anyone deal with this yet? Performance seems unaffected. I’ll ride it out a bit and see if it clears on its own. Truck has been driving 100% normal so far (before and after the light)

As an update, light didn’t clear itself but figured I’ll clear it once and see if it come back before taking it to the dealer. I’ve done about 200miles since clearing it and has not come back yet.
