Code P0132 Nissan Description

The P0132 diagnostic trouble code (DTC) for Nissan vehicles indicates a problem with the Air Fuel Ratio (A/F) sensor circuit for Bank 1 Sensor 1. This sensor is responsible for measuring the oxygen content in the exhaust gases before they enter the catalytic converter. The A/F sensor sends this data to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. When the A/F sensor circuit voltage is higher than normal, as indicated by this code, it can lead to incorrect fuel trim adjustments, affecting engine performance and emissions.
