2012 Nissan Murano Check Engine Light Reset

Resetting the check engine light on a 2012 Nissan Murano may seem simple, but a true fix requires diagnosing the underlying fault. A reset without repair can mask problems, cause intermittent failures, or void warranty benefits. Our team at Larry H. Miller Nissan Mesa recommends an OEM-level diagnostic first so resets are done only after the issue is resolved. We explain why dealership service is the smarter choice: certified technicians, factory tools, and Nissan OEM parts ensure longevity and transparency in pricing and repairs. We also back our work with warranty coverage and provide documentation required for future claims — remember that warranty-covered repairs must be completed at a certified dealership. For convenience we offer service financing and online booking; please schedule appointment and view our current service specials to save on required repairs.

2012 Nissan Murano Check Engine Light Codes

Common check engine light codes for the 2012 Nissan Murano include P0300 (random/multiple cylinder misfire), P0420 (catalyst system efficiency below threshold), P0133/P0135 (oxygen sensor slow response or heater circuit), and P0455 (evaporative leak). Each code has a progression of cost and risk: untreated misfires can damage the catalytic converter and lead to higher parts and labor costs; a faulty oxygen sensor reduces fuel economy and increases emissions; EVAP leaks may be inexpensive to fix initially but can trigger emissions test failures. At Larry H. Miller Nissan Mesa our approach centers on rapid diagnosis, OEM parts, and transparent estimates so you understand the cost-benefit of timely repair. We emphasize trained technicians, quick turnaround, and amenities that make your visit comfortable — from efficient check-in to clear communication.
