The O2 sensor, or oxygen sensor, on a 2002 Jaguar XK8 is a crucial component of the vehicle's emissions control system. It measures the level of oxygen in the exhaust gases, helping the engine control unit (ECU) optimize the air-fuel mixture for efficient combustion. This ensures better fuel efficiency, reduced emissions, and overall engine performance. If the O2 sensor fails, it can lead to poor fuel economy and increased emissions, potentially triggering a check engine light.
