Walker 245-1579 Mass Air Flow Sensor

Walker 245-1579 Mass Air Flow Sensor

Walker 245-1579 is a sensor-only mass air flow sensor for select Chrysler, Dodge, Fiat, Jeep, and Ram applications. It is built as a new replacement sensor, programmed and tested for fit, form, and function before release.

The Sensor Only line from Walker focuses on direct replacement electronics without the housing assembly. That makes it a practical choice when the original housing is serviceable and you need a replacement MAF sensor for accurate airflow measurement.

Detailed Description

Walker 245-1579 is a mass air flow sensor designed to measure incoming air so the engine control system can calculate fuel delivery accurately. This part number is built for select 2014-2018 Ram 2500 and Ram 3500 models, 2014-2017 Jeep Cherokee, 2015 Jeep Renegade, 2015-2017 Chrysler 200, 2015 Dodge Charger, 2015-2016 Dodge Challenger, and 2016-2018 Fiat 500X. If you are searching for a Walker MAF sensor for Ram 2500, Jeep Cherokee, or Chrysler 200 applications, 245-1579 is the direct replacement reference to review.

Walker Products has supplied fuel system components since 1946 and manufactures many of its high-demand sensors in the USA. The Sensor Only program is built around replacement electronics that are calibrated for the vehicle’s airflow range, with testing performed to verify operation before the part is released. This part cross-references Mopar 68144197AA and Standard Ignition MAS0463 for the same application.

What It Helps Address

• Rough idle caused by inaccurate airflow readings
• Check engine light related to MAF sensor performance
• Hesitation or poor throttle response
• Fuel trim issues from incorrect air measurement
• Driveability problems after sensor contamination or failure

Installation Notes and Tips

Confirm the connector shape, terminal count, and mounting pattern before installation. Because this is a sensor-only design, inspect the existing housing, air tubes, and connector area for dirt, oil residue, or damage before transferring the sensor. Handle the sensing element carefully and avoid touching it with bare hands.

For best results, verify the part number against the vehicle’s original MAF sensor and match the application exactly. Walker 245-1579 is intended for direct replacement use on the listed vehicles, including Ram 2500, Jeep Cherokee, and Fiat 500X applications.

Quality Assurance

Walker Products states that these sensors are 100% new, fully programmed, and tested for fit, form, and function. The company is ISO 9001 and IATF 16949 certified, and its MAF calibration process is verified through production testing and on-vehicle testing.
