2016 Nissan Pathfinder Check Engine Light Codes

Common codes for the 2016 Nissan Pathfinder include P0420 (catalyst efficiency), P0300–P0306 (random/multiple cylinder misfires), P0171/P0174 (lean condition), and sensor-related codes like P0130–P0167 for oxygen or upstream sensors. Each code points to different risks and costs when left unresolved: a P0420 left unaddressed often leads to catalytic converter replacement, which is a high-cost repair; frequent misfires (P030x) can ruin catalytic converters and reduce engine life; lean conditions (P0171/P0174) lower fuel economy and cause drivability concerns. At Larry H. Miller Nissan Mesa, we evaluate codes, explain the repair impact on performance and ownership costs, and recommend the most cost-effective path forward — often lower over time than independent shops because our diagnostics reduce repeat visits. Our Mesa service center provides OEM parts, certified technicians, and clear warranty handling so repairs preserve your vehicle’s coverage.
