捷豹XF 前氧传感器 C2D24922 / DX23-9D375-AA / 0258017547

Jaguar XF 2010-2015 with 2.0T, 3.0L and 5.0L gasoline engines: upstream oxygen sensor OEM numbers C2D24922, DX23-9D375-AA, and 0258017547 directly replace OEM parts. Sensor installed in the exhaust pipe monitors oxygen content and feeds ECU to adjust air–fuel ratio, ensuring combustion efficiency. Replacing resolves engine fault lights staying on, idle instability, or acceleration hesitation, and improves fuel economy and emissions. If after starting the vehicle, fuel consumption increases, exhaust emits black smoke, or a fault code related to the oxygen sensor appears on the dashboard, the sensor has failed and needs replacement.
