Walker 245-1620 Mass Air Flow Sensor
Walker Sensor Only Mass Air Flow Sensor
Walker 245-1620 is a sensor-only mass air flow sensor for select Land Rover applications. It is built as a new, tested replacement part for accurate airflow measurement and proper engine management on vehicles such as the Land Rover Defender, Discovery, and Range Rover family.
The Sensor Only line from Walker is designed for buyers who want a faster, more economical MAF sensor replacement without replacing the full housing assembly. For applications where the housing is still serviceable, this format keeps the repair focused on the sensor itself while maintaining OE-style fit, form, and function.
Key Features
- Walker part number 245-1620
- Sensor-only mass air flow sensor design
- Black housing with oblong 1-connector layout
- 4-wire, 4-terminal configuration with pin terminals
- 2 mounting holes for direct replacement fitment
- 100% new, never remanufactured
- Programmed and tested before release
- Built to meet OE-style calibration targets
Detailed Description
Walker Products engineers and tests its MAF sensors to deliver the airflow signal the engine control system expects. Part number 245-1620 is a direct replacement sensor for Land Rover Defender 110, Defender 130, Defender 90, Discovery, Discovery Sport, Range Rover, Range Rover Evoque, Range Rover Sport, and Range Rover Velar applications listed below. This part cross-references LR093998 for the same application.
Walker’s Sensor Only program is aimed at vehicles where the original housing can remain in service. The sensor is custom tuned for the full flow range and verified through production testing and on-vehicle validation. Walker Products also manufactures many high-demand MAF sensors in the USA using OEM-quality components and ISO 9001 / IATF 16949 manufacturing controls.
