Jaguar XF Downstream Oxygen Sensor, Lambda O2 Sensor, OEM 30751865

Upgrade your Jaguar and Volvo’s exhaust management with this downstream oxygen sensor (Lambda O2 sensor) designed as a precise OEM‑style replacement. This heated, piezoelectric sensor monitors exhaust gases after the catalytic converter, feeding accurate feedback to the engine control unit to optimize air–fuel ratio, boost fuel efficiency, and minimize emissions. It’s the ideal choice when you need reliable, long‑lasting performance for Jaguar XF, XJ, XK, and XKR models, as well as a range of Volvo vehicles from 2002 to 2014.

Why this sensor matters: a healthy downstream O2 sensor ensures your engine runs cleanly and efficiently, reduces false emissions readings, and helps maintain catalytic converter health. The heated design means faster warm‑up to operating temperature, which improves response during cold starts and enhances overall driveability. With OEM part numbers including 30751865 and related codes, this sensor is crafted to fit and function like the original, offering a seamless replacement experience.

Benefits & Tips

• Restores proper exhaust gas monitoring to improve fuel trim, idle stability, and throttle response after installation.
• Heated sensor design provides quicker stabilization of readings, especially in cold weather or short trips.
• Direct OEM‑style replacement for specified Jaguar and Volvo models—no complicated adaptations required, just plug in and go.
