## 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.
