"service bulletin - the mil comes on with one of these dtcs: p2646/p2651 (rocker arm oil pressure switch circuit low voltage). P2647/p2652 (rocker arm oil pressure switch circuit high voltage).

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.
