Code P244B Ford Description

This diagnostic checks to make sure that the aftertreatment Diesel Particulate Filter is present and functioning correctly. The Engine Control Module (ECM) uses the Exhaust Pressure Sensor to monitor the pressure differential through the aftertreatment Diesel Particulate Filter. The ECM will set the fault if it detects that the aftertreatment diesel particulate filter is not present in the aftertreatment/exhaust system. This DTC is a two trip fault. Active regeneration of the aftertreatment Diesel Particulate Filter will be disabled. The ECM will turn off the MIL lamp immediately after the diagnostic runs and passes.
