Some 2011-2014 Ford F-Super Duty vehicles equipped with the 6.7L diesel engine may exhibit an illuminated MIL and DTC P2043. This DTC sets due to a fault in the reductant heater assembly.

The repair requires replacement of the reductant heater and sender assembly (P/N BC3Z-5J225-M for chassis cab; or BC3Z-5J225-L for pickup models).
