Code P0158 2010 Nissan Sentra Description

The P0158 diagnostic trouble code (DTC) for a 2010 Nissan Sentra indicates an issue with the HO2S22 (Heated Oxygen Sensor 2 Bank 2) circuit registering high voltage. The HO2S22 is responsible for monitoring the oxygen levels in the exhaust gases and sending this information 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 incorrect fuel trim adjustments, affecting the engine's performance and emissions.
