Land Rover Part Number: LR012073 - Mass Air Flow Sensor
LR012073 is a Mass Air Flow Sensor fitted in the engine air intake on 5.0 AJ-V8 engines. Located in the air intake/air cleaner assembly, it measures the mass and density of incoming air and converts these readings into an electrical signal that the engine management system uses to calculate fuel delivery, adjust ignition timing, control mixture and manage transient response. Correct airflow measurement is particularly important on supercharged and turbocharged variants where intake temperature and corrected mass airflow affect boost control and fuel trim. On fitted models the sensor interfaces with the air cleaner housing and the engine wiring harness; replacement normally requires careful handling of the electrical connector and correct seating in the intake duct to avoid air leaks or contamination. Use the compatibility data below to confirm fitment against your V.I.N.
