Official summary
The positive crankcase ventilation (PCV) valve / oil separator may fail prematurely due to material aging. If this happens, the Malfunction Indicator Lamp (MIL) will illuminate. While this issue does not directly impact vehicle tailpipe emissions, the presence of an illuminated MIL can impact a vehicle’s ability to pass an emissions inspection.
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.
