Code P0158 2003 Nissan Altima Sedan Description

The diagnostic trouble code P0158 in a 2003 Nissan Altima Sedan refers to an issue with the HO2S22 circuit, indicating that there is a high voltage condition detected in the oxygen sensor 2 located in bank 2 of the exhaust system. The oxygen sensor, also known as the O2 sensor, plays a crucial role in monitoring the oxygen levels in the exhaust gases. This information is then sent to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion.
