The Mass Air Flow (MAF) Sensor ERR5595 measures the amount of air entering the engine and sends that information to the engine control system to calculate the correct fuel mixture. Proper airflow measurement is essential for smooth engine performance, fuel efficiency, and emissions control.

A failing MAF sensor can cause rough idle, poor acceleration, reduced fuel economy, or check engine lights. Replacing the sensor restores accurate airflow readings and helps maintain proper engine operation on Land Rover vehicles equipped with the 4.0L V8 GEMS engine.

This sensor installs directly into the intake system and connects to the factory wiring harness, making it a straightforward replacement for worn or faulty units.
