Code P0158 2005 Nissan Pathfinder Description
The P0158 code for a 2005 Nissan Pathfinder indicates an issue with the HO2S22 (Heated Oxygen Sensor 2 Bank 2) circuit reporting a 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 a variety of performance issues in the vehicle.
Common Causes of P0158 2005 Nissan Pathfinder
- Faulty HO2S22 sensor
- Damaged wiring or connectors in the sensor circuit
- ECM malfunction
- Exhaust system leaks
- Fuel system issues
