Technical Service Bulletin P1A25_ 2013-16 S — 2014 NISSAN SENTRA

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.
