Code P0152 2011 Nissan Pathfinder Description

The diagnostic trouble code P0152 in a 2011 Nissan Pathfinder indicates an issue with the Air Fuel Ratio (A/F) sensor circuit on Bank 2 Sensor 1. This sensor is responsible for measuring 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. When the ECM detects a high voltage signal from the A/F sensor, it triggers the P0152 code.
