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.

P1A25_ 2013-16 S	2022-03-15. Service bulletin. Engine Control Module (ECM) Reprogram and Oxygen Sensor Voltage Inspection Voluntary Emission Service Campaign Dealer Announcement: Nissan is conducting a Voluntary Emission Service Campaign to reprogram the Engine Control Module (ECM) and inspect the oxygen (O2) sensor voltage on certain MY2013-2016 Nissan Sentra SULEV vehicles identified in Service Comm. If the voltage is OK, no repair is necessary. If the voltage check results are “No Go”, dealers will diagnose and repair per the electronic service manual (ESM), and remedy any diagnostic trouble codes (DTCs) that may have been masked by a failure to detect the short circuit to ground condition. The current level software installed on the affected vehicles may not detect a rear oxygen (O2) sensor short to ground (SCG) condition. Undetected SCG may result in failure to pass emissions testing. What Dealers Should Do: 1.Verify if vehicles are affected by this Voluntary Emission Service Campaign using Service Comm or DBS National Service History – Open Campaigns I.D. P1A25. 2.Dealers are requested to remedy any affected vehicles in dealer pre-owned inventory to ensure customer satisfaction. 3.Dealers should use NTB22-006 to correct any vehicles subject to this campaign. 4.Once repaired, dealers should submit the claim, using the claims coding provided, and release the vehicle.
NTB22-007	2022-03-15. Service bulletin. 2013-2016 ALTIMA AND SENTRA; REAR OXYGEN SENSOR VOLTAGE INSPECTION SERVICE INFORMATION Nissan is committed to providing the highest levels of product quality and customer satisfaction. Therefore, Nissan is extending the emission warranty on the Rear Oxygen Sensor in the case of a short-to-ground condition to 20 Years or 200,000 miles, whichever occurs first. All other warranty terms, limitations, and conditions remain unchanged. During the warranty extension period, customers are eligible for annual Rear Oxygen Sensor voltage checks, upon request, to determine if a Rear Oxygen Sensor short-toground condition exists. If a Rear Oxygen Sensor short-to-ground condition does exist, Nissan will inspect and repair or replace, as necessary, the sensor or wiring and inspect for the existence of specific Diagnostic Trouble Codes (DTCs) for issues that may have been previously unidentified due to the short-to-ground condition. Only if one of the DTCs in Table A are first found after a short-to-ground repair, the corresponding issue(s) will also be corrected according to the service manual at no charge for parts and labor as part of this warranty extension.
