Service bulletin Campaign Circula
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
In some vehicles, corrosion can form in the differential pressure sensor, causing the Malfunction Indicator Light (MIL) to come on. If the MIL is on because of this issue, a vehicle will not pass an IM (emissions) inspection. In some vehicles under certain driving conditions, the MIL may come on due to an issue with the Engine Control Module (ECM) software. If the MIL is on because of this issue, the vehicle will not pass an IM (emissions) inspection. Update ECM software and/or replace the differential pressure sensor.
