2017 F-Super Duty – 6.7L – Illuminated Malfunction Indicator Lamp (MIL) – Diagnostic Trouble Code (DTC) U029D And/Or P2209

Some 2017 F-Super Duty vehicles equipped with a 6.7L engine may exhibit a MIL with DTC U029D and/or P2209.

 

This may be due to water intrusion, through the 14406 harness, into the wiring and/or connector for nitrogen oxides (NOx) sensor module 11.

To verify, disconnect the NOx sensor module 11 connector and check for presence of moisture and/or corrosion.

If found, do not attempt to service the connector or harness, replace the 14406 harness and NOx sensor module 11 to repair.

Engineering is investigating this concern, continue to monitor OASIS for updates on the latest information.
