Code P0158 2005 Nissan Maxima Description

The P0158 diagnostic trouble code (DTC) for a 2005 Nissan Maxima indicates an issue with the HO2S22 (Heated Oxygen Sensor 2 Bank 2) circuit registering high voltage. This sensor is responsible for measuring the oxygen content in the exhaust gases and providing feedback to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. When the HO2S22 circuit detects a voltage higher than the specified range, it triggers the P0158 code.
