Product Overview
The Mass Air Flow (MAF) Sensor C2Z18798 is a genuine OE-grade engine management component for for Jaguar XF (X250) and XJ (X351) models equipped with the 2.2L diesel (224DT) and 2.0L GTDI petrol engines. Installed in the intake tract after the air filter, it measures the volume and density of incoming air and transmits this data to the Engine Control Unit (ECU) for precise air-fuel mixture calculation. LR029074 is the Land Rover equivalent part number for the same component.

Signs of Failure
Check engine light – MAF-related DTCs
Rough idle or stalling – incorrect air-fuel mixture
Reduced fuel economy – inefficient combustion
Loss of power – poor acceleration and performance
