Service bulletin TSB 23-2259

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Some 2020-2022 Escape built and 2021-2023 Bronco Sport vehicles, built on or before 28-Sep-2022, equipped with a 1.5L Ecoboost engine and a 8F35 transmission may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P0420 stored in the powertrain control module (PCM). This may be due to the catalytic converter. To correct this condition, follow the Service Procedure to replace the catalytic converter.
