Official summary
Some customers may complain that the CHECK ENGINE light turns ON after a cold start or at high elevations (higher than 3,000m / 10,000 ft.), then exhibits lack of power from the engine with DTC P061B:00 stored in memory. This is caused by improper control software of the PCM. To eliminate this concern, the PCM control software has been modified.
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.
