FORD, LINCOLN · 2024-08-27

Some 2024 Edge and 2023 Nautilus vehicles built on 28-Aug-2023 and through 02-Apr-2024 equipped with a 2.0L EcoBoost engine may experience an illuminated malfunction indicator (MIL) with diagnostic trouble codes (DTCs) P0401 or P2457. Various engine cooling system symptoms which may include an internal/external leak, white smoke from the tailpipe, and/or over-temperature warnings may also be present. This may be due to a transmission fluid heater coolant control valve restricting flow and possibly causing the exhaust gas recirculation (EGR) cooler to crack. To correct the condition, follow the Service Procedure to replace the affected parts.

FORD, LINCOLN · 2020-07-10

Some 2019-2020 Edge/Nautilus vehicles equipped with a 2.0L EcoBoost engine may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTCs) P0128, P0217, P044C, P1026, P1285, P1299, P139A and/or P2457 stored in the powertrain control module (PCM). The vehicle may also exhibit low coolant level, white smoke from the tailpipe, an over temperature warning in the instrument panel cluster (IPC), and/or an external coolant leak. This may be due to the exhaust gas recirculation (EGR) cooler and/or settings in the PCM software. To resolve the condition, inspect the EGR cooler and/or update the PCM software.

Some 2018-2019 F-150 vehicles equipped with a 3.0L diesel engine built on or before 19-Oct-2018 may exhibit an illuminated MIL with DTC P2457 stored in the powertrain control module (PCM). This may be due to missing or loose screws in exhaust gas recirculation (EGR) system bypass module. Refer to Workshop Manual (WSM), Section 303-08E. If no concerns are present with the bypass module screws, refer to the Powertrain Control/Emissions Diagnosis (PC/ED) Manual for normal diagnostics. Engineering is investigating, monitor OASIS for updates.
