Code P2457 Ford Description

The Exhaust Gas Recirculation (EGR) cooler has internal coolant passages and metal fins between the passages to help carry away excessive exhaust gas heat. Engine coolant flowing through the EGR cooler helps cool the exhaust gases flowing to the EGR valve. The EGR cooler must remain within a specific temperature range to efficiently reduce emissions. The Engine Control Module (ECM) determines the efficiency of the EGR cooler by monitoring both EGR temperature sensors while the EGR valve is active. The Diagnostic Trouble Code (DTC) will be set when the ECM detects that the EGR cooler efficiency is lower than a calibrated value for greater than 100 s.
