The Rear Right Oxygen Sensor (also known as O2 Sensor) is a critical emissions and engine management component for specific Land Rover models. Installed in the rear exhaust system on the right side (after the catalytic converter), it monitors the oxygen content in the exhaust gas, transmitting real-time data to the engine control unit (ECU). This enables the ECU to fine-tune fuel injection and ignition timing, ensuring optimal combustion efficiency, reducing harmful emissions, and maintaining catalytic converter performance. As an OE-grade part, it meets Land Rover’s strict standards for measurement accuracy, high-temperature resistance, and durability, seamlessly integrating with the engine management system and performing reliably across extreme conditions (e.g., high exhaust temperatures, harsh weather).
Constructed from high-performance materials: the sensor’s sensing element uses zirconia or titania (for precise oxygen detection), while the housing and protective shield are made of heat-resistant stainless steel (to withstand exhaust gas temperatures up to 1000°C+). The electrical connector features corrosion-resistant plating to ensure stable signal transmission, even in humid or dusty engine bay environments.

Notes:
Rear Right Oxygen Sensors are position-specific (rear right only),engine-specific and model-specific—even within the same Land Rover model, different engine variants (gasoline/diesel, turbocharged/naturally aspirated) or production years require sensors with varying thread sizes, connector types, and calibration data. Note: The model "DISCOVERY SPORT1L550" provided may be a typo; it is corrected to the common model code "DISCOVERY SPORT (L550)" above—please confirm via VIN if there are special configurations.
Always verify the exact specification through your vehicle’s VIN (Vehicle Identification Number) or Land Rover’s official parts catalog to avoid fitment errors (e.g., check engine light, inaccurate emissions data, reduced fuel economy). During installation, use anti-seize compound on the sensor thread (avoiding the sensing element) and follow torque specifications from the service manual. Replace the sensor immediately if faults are detected (e.g., OBD error codes P013X/P017X, increased emissions, rough idling)—typical service intervals are 80,000–120,000 km, but harsh driving conditions may require earlier replacement.
Frequently Asked Questions
Q: How to determine if the bumper bracket needs replacement?
A: Signs of a failing bumper bracket include visible damage or deformation, misaligned bumper panels, unusual noises from the front end, or if the bumper appears loose or sagging on one side.
Q: What should be paid attention to when replacing the bumper bracket?
A: For optimal results, we recommend professional installation. Key considerations include ensuring proper alignment of all mounting points, checking for additional damaged components, and verifying all fasteners are properly torqued to specification.
