P2457: Your Car’s Dpf Is Clogged – Here’s What To Do
The P2457 code is related to the Exhaust Gas Recirculation (EGR) cooling system.
The EGR cooler helps cool the exhaust gases flowing to the EGR valve.
The Engine Control Module (ECM) monitors the efficiency of the EGR cooler by checking both EGR temperature sensors while the EGR valve is active. If the ECM detects that the EGR cooler efficiency is lower than a calibrated value for more than 100 seconds, the Diagnostic Trouble Code (DTC) will be set.
The P2457 code indicates that the EGR cooler is not performing as it should, which can lead to increased emissions.
