Code P0158 Jaguar Description

The P0158 code for Jaguar vehicles indicates an issue with the O2 sensor circuit high voltage for Bank 2 Sensor 2. The O2 sensor, also known as the oxygen sensor, plays a crucial role in monitoring the oxygen levels in the exhaust gases to help the engine control module (ECM) adjust the air-fuel mixture for optimal combustion. Bank 2 Sensor 2 refers to the sensor located downstream of the catalytic converter on the side of the engine that houses cylinder 2.
