Land Rover Range Rover Rear Oxygen Sensor MHK500870 Exact OE Match

Range Rover – engine check light, high fuel consumption or weak acceleration? Typical symptom is downstream oxygen sensor aging/failure; sensor reports exhaust oxygen to ECU to optimize fueling and catalytic efficiency; OEM MHK500870 matches Range Rover (2010-2022, including 3.0L/5.0L petrol). Install with dedicated socket; avoid over-tightening and keep wiring away from exhaust heat.
