Womala Middle Oxygen Sensor C2C22679 for Jaguar XJ XF XK

Product Overview

The Intermediate Oxygen Sensor C2C22679 is a Genuine OE-grade component for a wide range of for Jaguar vehicles. Also known as a downstream or post-catalyst oxygen (O2) / lambda sensor, it monitors the oxygen content in the exhaust stream after the catalytic converter, providing feedback to the Engine Control Unit (ECU) to optimize the air-fuel ratio and ensure efficient emissions control . This sensor is the middle/rear position sensor (post-catalyst) and fits both left and right rear/lower positions .

Key Features

• Intermediate/rear position – post-catalytic converter (downstream) sensor

• Heated 4-wire sensor – reaches operating temperature quickly for accurate readings 

• OE-grade quality – Denso is the OE manufacturer for this part 

• Fits both rear positions – one part number covers left and right rear locations 

• Direct-fit replacement – plug-and-play with factory connector 

OE Cross-Reference

💡 C2C22679 is the Genuine Jaguar part number. Denso is the OEM supplier for this sensor.

Vehicle Fitment

Detailed engine compatibility:

• 3.0L V6 Petrol (S‑TYPE, XF, XJ)

• 4.2L V8 Petrol (XF, XJ, XK, S‑TYPE)

• 5.0L V8 Petrol (XF, XFR)

⚠️ Important: This is the intermediate/rear (post-catalytic converter) oxygen sensor. A different part number is required for the front (pre-catalyst) position. Fitment varies by model year, production date, and VIN range – verify before ordering .

Signs of Failure

• Check engine light – O₂ sensor-related DTCs

• Poor fuel economy – incorrect air-fuel ratio 

• Failed emissions test – elevated pollutant levels 

• Poor driveability – hesitation or rough running 

💡 O2 sensors are one of the more commonly failed sensors in a Jaguar emissions control system. Continuous exposure to exhaust temperatures ranging from 300°–700°F over time causes the sensor element to lose its ability to create voltage, making the sensor give incorrect readings .

Critical – Verify Your VIN Before Ordering

Oxygen sensors are VIN‑, engine‑, and position‑specific. Variations in engine type, model year, production date, and VIN range affect fitment. Provide your VIN – our team confirms exact compatibility before dispatch. We cannot accept returns for misordered parts without VIN verification.

💡 Installation Tip: Professional installation recommended. A 22mm or 7/8″ O2 sensor socket is required for removal . Apply anti-seize compound to threads (avoiding the sensor tip) and torque to manufacturer specifications.
