P0158 Nissan Code - HO2S22 Circuit High Voltage

Quick Answer

The P0158 diagnostic trouble code (DTC) for Nissan vehicles refers to an issue with the HO2S22 (Heated Oxygen Sensor 2 Bank 2) circuit reporting high voltage. Common causes include Faulty HO2S22 sensor, Wiring issues such as frayed wires or corrosion, Exhaust leaks near the sensor. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P0158 Nissan Description

The P0158 diagnostic trouble code (DTC) for Nissan vehicles refers to an issue with the HO2S22 (Heated Oxygen Sensor 2 Bank 2) circuit reporting 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 sensor reports a high voltage, it means that the engine is running rich (too much fuel or too little air) which can lead to decreased fuel efficiency, increased emissions, and potential damage to the catalytic converter over time.
