Code P0158 2007 Nissan Pathfinder Description

The P0158 code for a 2007 Nissan Pathfinder refers to an issue with the HO2S22 sensor circuit, indicating that there is a high voltage condition. The HO2S22 sensor is part of the vehicle's oxygen sensor system, which monitors the oxygen levels in the exhaust gases to ensure proper fuel mixture for efficient combustion. A high voltage reading from this sensor can disrupt the engine's performance and emissions control system, leading to decreased fuel efficiency, rough idling, and potentially causing damage to the catalytic converter.
