Code P0158 2007 Nissan Sentra Description

The P0158 code for a 2007 Nissan Sentra indicates an issue with the HO2S22 sensor, specifically that the circuit is registering a high voltage. The HO2S22 sensor, also known as the downstream oxygen sensor, is responsible for monitoring the oxygen levels in the exhaust gases after they have passed through the catalytic converter. This information is crucial for the engine control module (ECM) to adjust the air-fuel mixture for optimal performance and emissions control.
