Code P0153 2011 Nissan Pathfinder Description

The P0153 diagnostic trouble code (DTC) indicates that the air-fuel ratio sensor circuit in Bank 2 Sensor 1 of a 2011 Nissan Pathfinder has a slow response. This sensor is responsible for monitoring the oxygen levels in the exhaust gases and sending this information to the engine control module (ECM). The ECM uses this data to adjust the air-fuel mixture for optimal combustion efficiency. A slow response from the sensor can lead to inaccurate readings and affect the engine's performance.
