Land Rover Jaguar Oxygen Sensor 0258030086 LR049883 EJ32-9G444-AB

When your Range Rover or Jaguar exhibits rough idle, high fuel consumption, check engine light on, or exhaust odor during acceleration, it is usually oxygen sensor aging or failure. This sensor, functioning normally, continuously feeds the ECU with air–fuel ratio signals to help precise fuel injection and ensure combustion efficiency and emission compliance. Compatible models include Land Rover Range Rover, Discovery, Sport, and Jaguar XF, XJ with 3.0L/5.0L engines. OEM numbers 0258030086, LR049883, EJ32-9G444-AB. Install with dedicated socket to avoid stripping threads; ensure harness connectors are clean and free of oil; after installation clear fault codes and road test.
