Official summary
The affected vehicles have a Powertrain Control Module (PCM) calibration that could, over time, reduce the effectiveness of the emissions control system and the monitoring accuracy of the catalytic converter’s efficiency. As a result, the Malfunction Indicator Light (MIL) may illuminate for low catalyst efficiency even though a catalytic converter repair may not be necessary.
Vehicles covered
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.
