FORD · 2023-07-14
Some 2023 F-Super Duty vehicles equipped with a 6.7L engine may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTC) U029D, U029E, U02A1, U02A3, P2209, P24D0, P22A7, and/or P23B5. This may be due to a wiring chafe on harness 14406 near connector C146 touching the exhaust gas recirculation (EGR) cooler on the right side of the engine. Before performing normal diagnostics, inspect 20 amp fuse F18 (position 26). If fuse F18 is found open, inspect the 14406 harness for contact with the EGR cooler and repair as necessary. Refer to Wiring Diagram, Cell 005 for repair procedures. If no damage is found, refer to Workshop Manual, Section 303-08A for normal diagnostics.

Some 2021 F-Super Duty vehicles equipped with a 6.7L engine and built on 07-Jul-2021 and through 11-Jul-2021 may have previously not properly completed powertrain control module (PCM) reprogramming or programmable module installation (PMI) resulting with diagnostic trouble code (DTC) U029E. PCM reprogramming and PMI for these vehicles has been updated in the Ford Diagnosis and Repair System (FDRS) scan tool. Programming no longer attempts to incorrectly program the nitrogen oxides sensor module 12 (NOX12) and should not result in a U029E DTC present. For vehicles that already have a U029E DTC present, NOX12 module replacement is necessary before attempting PCM programming.

Some 2021 F-Super Duty vehicles equipped with a 6.7L engine and built on 07-Jul-2021 and through 11-Jul-2021 may not properly complete powertrain control module (PCM) reprogramming or programmable module installation (PMI) resulting with diagnostic trouble code (DTC) U029E. PCM reprogramming and/or PMI for vehicles in this build date range is not recommended at this time. Monitor OASIS broadcast messages for updates. A fix is expected before the end of February 2022.

Some 2017-2020 F-Super Duty vehicles equipped with a 6.7L engine built on or before 10-Jun-2020 may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTCs) U029D, U029E, P22A7 and/or P2209 in the powertrain control module (PCM). This may be due to water intrusion into the oxides of nitrogen (NOx) connectors. To correct the condition, follow the Service Procedure to inspect the NOx sensor module and replace the 14406 wire harness.

Diagnostic Tip for Malfunction Indicator Lamp (MIL) Illuminated - DTC P249D, P249E, U029D, U029E Set Some customers may comment that the MIL is illuminated. The technician may find one or more of the following DTCs set: • U029D • U029E • P249D • P249E Note: The graphic above depicts an example of a torn and missing seal. • Moisture intrusion past a damaged (1) seal located in the connector for the NOx sensor wiring harness. • Missing (2) seal located in the connector for the NOx sensor wiring harness. Correction If you encounter a vehicle with the above concern, perform normal diagnostics for the codes set. ⇒ If diagnostics lead to NOx sensor replacement, inspect the mating chassis electrical connector for corrosion. Clean and repair as necessary.
