Service bulletin TSB210127-090920
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
This Technical Service Bulletin describes the verification and resolution of misfire fault codes without any audible misfire or performance loss (false misfire). This can be caused by aftermarket exhaust gas pressure sensors not providing equivalent signal as genuine Cummins® exhaust gas pressure sensor. This is an update to a previously submitted technical service bulletin.
