Code P0131 2010 Nissan Pathfinder Description

The P0131 diagnostic trouble code (DTC) for a 2010 Nissan Pathfinder indicates an issue with the Air Fuel Ratio (A/F) circuit on Bank 1 Sensor 1. This sensor is located in the exhaust system before the catalytic converter and is responsible for measuring the oxygen content in the exhaust gases. The A/F sensor sends this data to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion.
