Official summary
Some of the vehicles listed in the Model statement above may exhibit an illuminated malfunction indicator lamp (MIL) with DTCs P0301-P0306, P0201-P0206 and/or various other powertrain DTCs stored in the PCM. This may be due to the engine harness contacting the hose crimp end or spring clamp tangs on the exhaust heat exchanger heater hose assembly.
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.
