Code P0153 2006 Nissan Pathfinder Description

The P0153 diagnostic trouble code (DTC) for a 2006 Nissan Pathfinder indicates an issue with the Air Fuel Ratio (A/F) sensor circuit on Bank 2 Sensor 1. This sensor is responsible for monitoring the oxygen content in the exhaust gases and providing feedback to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. A slow response from this sensor can lead to poor engine performance, decreased fuel efficiency, and increased emissions.
