This fault code becomes active when the aftertreatment diesel oxidation catalyst inlet and aftertreatment diesel particulate filter inlet temperature sensors do not detect the presence of a catalyst in the aftertreatment system. This can be caused by tampering with the catalyst system, the catalyst has been removed from the vehicle, or a damaged catalyst
