Code P0158 2012 Nissan Sentra Description
The P0158 OBD-II trouble code for a 2012 Nissan Sentra indicates an issue with the HO2S22 sensor circuit, specifically reporting high voltage. The HO2S22 sensor, also known as the downstream oxygen sensor or oxygen sensor 2, is responsible for monitoring the exhaust gases after they have passed through the catalytic converter. The sensor measures the oxygen content in the exhaust to help the engine control module (ECM) adjust the air-fuel mixture for optimal combustion.
Common Causes of P0158 2012 Nissan Sentra
- Faulty HO2S22 sensor
- Wiring or connector issues
- Exhaust leaks
- Engine misfires
- Exhaust system damage
Symptoms of P0158 2012 Nissan Sentra
- Decreased fuel efficiency
- Rough idle
- Hesitation during acceleration
