Product Details

Walker 245-1601 is part of Walker Products’ Complete Assembly program, which includes replacement sensors and housing assemblies for applications where the full unit is preferred. Walker states that many of these MAF sensors are manufactured in the USA using OEM-quality components, custom circuit boards, and application-specific programming. This part cross-references Delphi AF10669 for the same application.

Compatible With 2017-2022 Hyundai Ioniq and 2017-2022 Kia Niro, this mass air flow sensor is intended for vehicles that require the complete assembly configuration. If you are searching for a 2017-2022 Hyundai Ioniq mass air flow sensor or a 2017-2022 Kia Niro complete MAF assembly, part number 245-1601 is the direct-fit reference to review.

What It Helps Solve

• Incorrect airflow readings from a failing MAF sensor
• Rough idle caused by inaccurate air metering
• Driveability issues related to fuel trim imbalance
• Check engine lights tied to mass air flow sensor faults
• Performance loss from contaminated or worn sensor elements

Installation Notes and Tips

Inspect the air inlet tract and connector area before installation. Because this is a complete assembly, verify that the housing, connector, and mounting points match the original unit on your Hyundai Ioniq or Kia Niro before replacement. Avoid touching the sensing element and confirm all electrical connections are clean and fully seated.
