Land Rover Range Rover Oxygen sensor CPLA-9G444-GA replacement LR035747 0258030458

When your Range Rover experiences idle instability, abnormal fuel consumption, frequent engine warning light illumination, or sluggish acceleration, this typically indicates aging or failure of the oxygen sensor, which cannot accurately monitor the oxygen content in the exhaust. Under normal operation, this sensor provides real-time feedback of the air-fuel ratio to the ECU, ensuring optimal combustion efficiency, reducing emissions, and improving power response. Compatible models include Range Rover (L405) and Range Rover Sport (L494) equipped with 3.0L/5.0L engines, OEM number CPLA-9G444 (alternative to LR035747, 0258030458). When installing, be sure to use a dedicated socket to avoid stripping threads, and ensure the sensor harness does not contact the exhaust pipe or undercarriage components to prevent high-temperature melting.
