Some 2011-2014 Ford F-Super Duty trucks equipped with a 6.7L diesel engine may exhibit an illuminated MIL and DTC P2043. This DTC sets due to a fault in the reductant heater assembly.
Using an Integrated Diagnostic System (IDS) or equivalent, check for DTCs. If P2043 is present, replace the reductant heater assembly. Refer to workshop manual Section 303-08.
