Code P0137 2010 Nissan Sentra Description

The P0137 code for a 2010 Nissan Sentra indicates a problem with the Heated Oxygen Sensor (HO2S) circuit having low voltage for Bank 1 Sensor 2. The HO2S is responsible for measuring the oxygen content in the exhaust gases and sending this information to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. Bank 1 Sensor 2 refers to the sensor located downstream of the catalytic converter on the side of the engine where cylinder 1 is located.
