Oxygen Sensor Upstream Air Fuel Ratio for Jaguar XJ XF XK S-TYPE 2006-2010

Upgrade your Jaguar’s fueling precision with the Oxygen Sensor Upstream Air-Fuel Ratio for Jaguar XJ XF XK S-TYPE 2006-2010. This upstream (pre-cat) sensor continuously monitors the exhaust oxygen content before it enters the catalytic converter, delivering real-time feedback to the engine control unit. By maintaining the optimal air-fuel ratio, it helps improve fuel economy, reduce emissions, and restore smooth, responsive throttle behavior across a wide range of Jaguar V8 configurations from 2006 to 2010.

Designed to fit a broad lineup—including S-Type, XF, XJ, XK, XJR, and XKR models—this sensor covers 3.0L V6, 4.2L V8, and 5.0L V8 engines in 2006–2011 Jaguars. The sensor features a heated type element and a piezoelectric sensing mechanism for fast, accurate readings even during cold starts, helping your engine reach optimal performance quicker and stay within desired emissions targets.

Key identifiers for this replacement include OE-style part numbers such as 6R83-9F472-AC, 6R839F472AC, and related equivalents (6R83 9F472 AC, 6R839F472AB) as well as alternative codes like 2112005140, 2112005210, C2P8810, and C2C22681, with a 234-9125 reference. The part is intended for front/upstream, pre-cat oxygen sensing in a heated, piezoelectric configuration, ensuring reliable readings across Jaguar’s varied engine architectures.

To ensure a perfect fit, please verify compatibility by cross-checking the original part number and cross-referenced codes. If there’s any uncertainty, share the part number or original product photo with us before ordering so we can confirm fitment within 24 hours (excluding weekends and holidays).

Benefits & Tips
