Affected vehicles: Certain 2004-2005 F250/350/450/550, Excursion and E350/450 vehicles equipped with 6.0L diesel engines.

Situation: On certain affected vehicles, corrosion may exist at the electrode surface on the Exhaust Pressure (EP) sensor; fuel delivery timing during cold weather may not be optimal; and/or Exhaust Gas Recirculation (EGR) system operation at idle may not be optimal. These conditions may cause “Check Engine” light illumination, lack of power, hard starting, and/or rough engine operation. In addition, the on-board diagnostic (OBD) system on F-250/350, Excursion, and E350/450 vehicles may not properly monitor the performance of the emission control system.
