Code P0132 2011 Nissan Sentra Description

The P0132 diagnostic trouble code (DTC) for a 2011 Nissan Sentra indicates an issue with the Air Fuel Ratio Circuit High Bank 1 Sensor 1. This code specifically relates to the oxygen sensor located in the exhaust system before the catalytic converter on the bank 1 side of the engine. The oxygen 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.
