2010 Nissan Xterra Check Engine Light Codes

Common check engine light codes for a 2010 Nissan Xterra often include P0420 (catalytic converter efficiency), P0135 (oxygen sensor heater circuit), P0300 (random/multiple cylinder misfires), and P0456 (EVAP small leak). Ignoring these codes can lead to escalating costs: a loose EVAP system part might be inexpensive to fix but, if neglected, can compromise emissions and trigger additional sensors; a failing oxygen sensor or catalytic converter can reduce fuel economy and eventually require more costly exhaust repairs. At Larry H. Miller Nissan Mesa in Mesa, AZ, our certified technicians diagnose codes precisely, explain repair options, and use OEM parts to restore performance. Choosing dealership service delivers immediate savings through accurate troubleshooting and long-term value by avoiding unnecessary or incorrect repairs. We also offer transparent pricing, service financing, and targeted service specials to make repairs affordable.
