2011 Nissan Armada Check Engine Light Codes

The 2011 Nissan Armada typically stores common OBD-II codes such as P0300 (random/multiple misfires), P0420 (catalyst system efficiency below threshold), P0171 (system too lean), P0455 (evaporative emission control system large leak), and various O2 sensor codes. Left unaddressed, misfires can damage pistons and the catalytic converter, leading to repairs that range from a few hundred dollars for sensors and ignition components to thousands for a failed catalytic converter. At Larry H. Miller Nissan Mesa in Mesa, AZ, our certified technicians diagnose codes with OEM-grade tools and explain repair costs and timelines clearly, so you understand immediate and long-term savings. Promptly fixing a lean condition or bad oxygen sensor preserves fuel economy and prevents more expensive downstream failures. Our service advisors will review repair options, factory warranty considerations, and available service specials, and we offer service financing to ease payment. Trust our dealership for correct repairs the first time — fewer repeat visits mean lower lifetime ownership costs for your 2011 Nissan Armada.
