Code P0138 2013 Nissan Rogue Description

The P0138 code on a 2013 Nissan Rogue indicates an issue with the HO2S12 (Heated Oxygen Sensor 1 Sensor 2) circuit registering high voltage. The HO2S12 sensor is responsible for monitoring the oxygen levels in the exhaust gases and providing feedback to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. When the voltage from the sensor is higher than expected, it can lead to performance issues and potentially cause damage to the vehicle's systems.
