Product Details

Walker Sensor Only is the product line for drivers and technicians who need a replacement MAF sensor without purchasing a complete sensor-and-housing assembly. Walker engineers tune the flow characteristics across the operating range so the sensor matches the vehicle’s air metering needs and supports OE-style fuel trim performance. Many high-demand part numbers are manufactured in the USA, and the brand’s production process includes on-vehicle verification.

This Walker mass air flow sensor, part number 245-1618, cross-references Ford LC3Z12B579A for the same application. It is listed for 2024 Ford Mustang, 2021 Ford F-150, 2020-2022 Ford F-250 Super Duty, and 2020-2022 Ford F-350 Super Duty in sensor-only configurations.

What It Helps Address

• Rough idle caused by inaccurate airflow readings
• Hesitation or stumble during acceleration
• Check engine light related to MAF sensor performance
• Fuel trim issues from incorrect air measurement
• Poor drivability after a failing original sensor

Installation Notes

Confirm the connector shape, terminal count, and mounting points before installation. Sensor-only replacement is typically used when the housing is serviceable and clean. Handle the sensing element carefully and avoid touching it with bare hands or exposing it to contamination during installation.

Compatible With 2024 Ford Mustang, Sensor Only; 2021 Ford F-150, Sensor Only; 2020-2022 Ford F-250 Super Duty, Sensor Only; and 2020-2022 Ford F-350 Super Duty, Sensor Only.
