Official summary

This Service Information Bulletin announces design changes to the engine?s knock sensor which will help improve vehicle assembly line efficiency and increase durability. In some cases, the Check Engine light may illuminate and a knock sensor-related DTC set in the ECM memory: P0327, P0328, P0332 and P0333. The knock sensor for DIT engines is now utilized for NA engines to improve durability and resistance to heat.

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.
