Womala Mass Air Flow Sensor for Land Rover Discovery MK III and Range Rover Sport

Core Functions

• Air Flow Measurement: The primary function is to precisely measure the mass of air entering the engine, providing critical data for the ECU to calculate optimal fuel delivery.
• Engine Performance Optimization: Enables the ECU to adjust fuel injection and ignition timing based on real-time air flow data, ensuring smooth engine operation, maximum power output, and reduced emissions.
• Fault Detection: Monitors air flow consistency and triggers diagnostic trouble codes (DTCs) if anomalies are detected (e.g., restricted air flow, sensor failure), alerting to potential engine issues.

 Compatible Vehicles

This Mass Air Flow Sensor is tailored for the following Land Rover models and their respective OE numbers:

Notes: Mass Air Flow Sensors are engine-specific and model-specific—even within the same Land Rover model series, different engine variants (e.g., gasoline vs. diesel, turbocharged vs. naturally aspirated) require sensors with varying measurement ranges and calibration. Confirm the exact specification via your vehicle’s VIN or Land Rover’s official parts catalog to avoid engine performance issues (e.g., rough idling, reduced power, increased fuel consumption). During installation, ensure proper electrical connection and air intake sealing to maintain measurement accuracy. Regularly inspect for signs of failure (e.g., check engine light, abnormal engine behavior, sensor contamination) and replace the sensor at Land Rover’s recommended intervals (typically 80,000–120,000 km) or immediately if faults are detected.
