2014 Nissan Maxima Check Engine Light Reset

Resetting the check engine light on a 2014 Nissan Maxima might seem straightforward, but a simple reset without repair only hides symptoms and risks further damage. A true reset is part of a complete service sequence that begins with a diagnostic scan to capture stored trouble codes and freeze-frame data. At Larry H. Miller Nissan Mesa in Mesa, AZ, our factory-trained technicians use OEM-level scanners and software to read manufacturer-specific codes, clear them properly, and verify that the underlying fault has been corrected. This approach protects your vehicle’s long-term reliability and helps preserve any active warranties — repairs covered under warranty must be completed at a certified dealership to remain valid. We combine transparent pricing and documented repairs so you see immediate value and long-term savings: correct diagnosis prevents repeat visits, incorrectly installed parts, and escalating labor. If you need a quick follow-up or want to understand repair options, check our service specials and schedule service online to reserve a convenient time with our service team.

2014 Nissan Maxima Check Engine Light Codes

Common codes for a 2014 Nissan Maxima include P0420 (catalyst efficiency below threshold), P0300 (random/multiple cylinder misfire), P0171 (system too lean), P0455 (evaporative emission system leak), and various oxygen sensor or mass airflow sensor codes. Left unaddressed, these faults can reduce fuel economy, increase emissions, and cause catalytic converter failure — a repair that can be very costly. At Larry H. Miller Nissan Mesa we explain the cost implications of each code and recommend fixes that deliver the best long-term value. For example, addressing a misfire early can prevent engine damage and avoid catalytic converter replacement later; repairing an EVAP leak promptly avoids fuel vapor loss and improves fuel efficiency. Our Mesa, AZ service center emphasizes speed without sacrificing quality — OEM parts, certified technicians, and thorough post-repair verification ensure you pay for the right solution once.
