Womala Mass Air Flow Sensor for Land Rover Discovery MK III and Range Rover Sport
The Mass Air Flow Sensor is a critical engine management component
for specific Land Rover models. Installed in the engine’s air
intake system, it measures the volume and density of air entering
the engine, transmitting this data to the engine control unit
(ECU). The ECU then adjusts fuel injection and ignition timing for
optimal combustion, ensuring efficient engine performance, fuel
economy, and emission control. As an OE-grade part, it meets Land
Rover’s strict standards for measurement accuracy, durability, and
environmental resistance, seamlessly integrating with the engine
management system and performing reliably across diverse driving
conditions (e.g., cold starts, high-speed acceleration, heavy-load
operation).
Constructed from precision-engineered materials: the sensor element
uses hot-wire or hot-film technology (for accurate air flow
measurement), while the housing is made of heat-resistant plastic
or metal to withstand intake air temperatures and engine bay
conditions. The electrical connectors are designed for secure,
corrosion-resistant contact to ensure consistent signal
transmission.
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:
| Item | Details |
|---|---|
| Product OE Number | PHF500101/LR012073/PHF000140/LR035726 |
| Land Rover Model | RANGE ROVER SPORT(L320) DISCOVERY IV (L319) FREELANDER 2(L359) RANGE ROVER IV (L405) |
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.
Frequently Asked Questions
Q: How to determine if the bumper bracket needs replacement?
A: Signs of a failing bumper bracket include visible damage or deformation, misaligned bumper panels, unusual noises from the front end, or if the bumper appears loose or sagging on one side.
Q: What should be paid attention to when replacing the bumper
bracket?
A: For optimal results, we recommend professional installation. Key considerations include ensuring proper alignment of all mounting points, checking for additional damaged components, and verifying all fasteners are properly torqued to specification.
