Oxygen Sensor Voltage Inspection
Warranty Extension
Dealer Announcement:
In the interest of customer satisfaction, Nissan is providing a limited warranty extension to certain MY2013-2016 Nissan Altima 2.5L (SULEV and 50 states emissions) and certain MY2013-2016 Nissan Sentra vehicles (50 states only) to allow for annual rear oxygen sensor voltage checks, upon request, to determine if a rear oxygen sensor short-to-ground condition exists. If a rear oxygen sensor short-to ground condition exists, Nissan will inspect and repair or replace, as necessary, the sensor or wiring and remedy any diagnostic trouble codes that may have been masked by a failure to detect a possible rear oxygen (O2) sensor short to ground (SCG) condition. If those DTCs are first found only after a short-to-ground repair, the Limited Emission Warranty extension will cover the costs of parts and labor to inspect and repair the corresponding issue(s).
Affected vehicles may fail to detect the rear oxygen (O2) sensor short circuit to ground (SCG). Undetected SCG may result in failure to pass emissions testing.
Owners of eligible vehicles will receive a notification indicating their eligibility for the following:
â?¢ Annual rear oxygen sensory voltage check during the extended warranty coverage
â?¢ Limited warranty extension for the rear oxygen sensor to 20 years/200,000 miles (whichever occurs first)
What Dealers Should Do:
1. Verify if vehicles are eligible for this limited Warranty Extension using the warranty extension page of Service Comm.
2. Dealers should perform a voltage check and, if necessary, remedy any eligible vehicles subject to this warranty extension to ensure customer satisfaction using NTB22-007.
3. The service department should submit the applicable warranty claim for the action(s) performed.
