2016 Nissan Altima Check Engine Light Codes

In Mesa, Arizona, drivers turn to Larry H. Miller Nissan Mesa when a 2016 Nissan Altima shows a check engine light because common codes—P0171 (lean condition), P0420 (catalyst efficiency), P0300 (random misfire), and oxygen-sensor faults—are diagnosed with OEM-grade tools and Nissan-specific expertise. A P0171 left untreated can reduce fuel economy and damage sensors; a prompt repair saves money on fuel and sensor replacement. A P0420 ignored long-term can lead to catalytic converter failure, which is substantially more expensive to replace than early sensor repairs. Misfire codes like P0300 may signal ignition coil or spark plug issues; delaying repair risks engine damage and higher repair bills. Choosing our dealership means you get an accurate code read, a clear estimate, and certified technicians who explain immediate repair costs versus long-term savings. We stock many OEM parts for timely repairs, and our service financing options let you address issues now and pay later. For the most reliable outcome and genuine Nissan parts, schedule service and check available service specials before your visit to maximize value.

2016 Nissan Altima Check Engine Light Reset

Resetting the check engine light on a 2016 Nissan Altima may be a short-term fix but does not address underlying faults. At Larry H. Miller Nissan Mesa we explain why a simple reset without repair can lead to recurring codes, missed emissions issues, and potential warranty complications. Our technicians perform a full scan, document stored and pending codes, and advise on necessary repairs using OEM parts for lasting results. We provide transparent pricing and highlight how authentic Nissan components and factory-trained technicians extend the life of your vehicle while often costing less than repeated work at independent shops. Resets performed here are paired with diagnostic reports and recommended next steps so you understand immediate costs and long-term savings. If coverage applies, remember warranty repairs must be completed at a certified dealership to keep protections intact. To eliminate the root cause rather than chase recurring lights, schedule a service and review our service specials for additional savings.
