Service bulletin TSB200175-081920

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

The parts catalog on QuickServe® Online (QSOL) references the incorrect exhaust gas recirculation (EGR) differential pressure sensor, which may result in an incorrect EGR differential pressure sensor being installed on on-highway natural gas engines during a service event. Incorrect EGR differential pressure sensor part number being installed can lead to incorrect repair and possibly repeat repairs.
