2014 Nissan Xterra Check Engine Light Codes

At Larry H. Miller Nissan Mesa in Mesa, AZ, we diagnose the most common check engine codes for the 2014 Nissan Xterra with speed and transparency. Popular trouble codes include P0420 (catalyst efficiency below threshold), P0300–P0306 (engine misfires), P0130–P0167 (oxygen sensor circuit faults), and P0440 (evaporative emission control system). Ignoring codes like P0420 can lead to reduced fuel economy and eventual catalytic converter failure — a repair that can cost substantially more than timely service. Misfire codes can cause drivability issues and long-term engine damage if allowed to persist. Our certified Nissan technicians prioritize accurate diagnosis to avoid unnecessary parts replacement and to recommend cost-effective repairs.
