Land Rover Range Rover Sport 3 Oxygen Sensor MHK500910 Original Number Replacement

When your Land Rover Range Rover Sport 3.0L engine shows idle instability, acceleration lag, abnormal fuel consumption, or the check engine light with NOx sensor fault codes, it suggests the original oxygen sensor may be aging or carbon buildup causing air-fuel imbalance. This sensor monitors oxygen content in exhaust and feeds ECU to adjust fuel for emission compliance and power. OEM number MHK500910; fits Range Rover Sport 3.0L (2010-2017). Install with engine cold; use a dedicated socket to carefully remove old sensor; avoid thread damage; apply anti-seize and ensure secure connection.
