2014 Nissan Titan Check Engine Light Codes

Common fault codes for the 2014 Nissan Titan cover oxygen sensors, catalytic converter efficiency, misfires (P0300–P0308), and evaporative system leaks (P0440 series). In Mesa, Larry H. Miller Nissan Mesa leverages local knowledge and OEM diagnostics to rapidly identify which code is present and what it means for your immediate safety and future maintenance costs. For example, a persistent O2 sensor fault can lower fuel economy and, left unrepaired, damage the catalytic converter — a repair that can cost significantly more than addressing the sensor early. Evaporative system leaks often stem from inexpensive items like gas caps or hoses; repairing these quickly avoids emissions test failures and keeps operating costs low. Our service department explains the cost-benefit of each repair, highlights long-term savings achieved with OEM parts, and offers transparent pricing so you know what to expect. We also honor warranty terms — any covered repairs must be performed at a certified dealer to remain valid — and provide service financing if you prefer to pay over time.
