Official summary
* This article supersedes TSB 25-2269 to update vehicles affected. Some of the vehicles listed in the Model statement above may exhibit an incorrectly illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P0420 stored in the powertrain control module (PCM). This may be due to the software in the PCM.
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
