Product Details

Walker Products’ Complete Assembly program is intended for applications where replacing the full sensor and housing is preferred over sensor-only service. That approach helps preserve the correct connector interface and air tube condition, which matters when the original housing or air path has contamination or wear. Walker also manufactures many high-demand MAF sensors in the USA using OEM-quality components and custom engineered circuit boards. This part cross-references Hyundai/Kia OE number 281642M400 for the same application.

Compatible vehicle coverage includes Fits 2026 Hyundai Santa Cruz, N/A; Fits 2022-2024 Hyundai Santa Cruz, N/A; Fits 2021-2026 Hyundai Santa Fe, N/A; Fits 2020-2026 Hyundai Sonata, N/A; Fits 2022-2026 Hyundai Tucson, N/A; Fits 2021-2024 Kia K5, N/A; Fits 2021-2024 Kia Sorento, N/A; and Fits 2023-2024 Kia Sportage, N/A. If you are replacing a Hyundai Sonata MAF sensor or a Kia Sportage mass air flow sensor, verify the connector style and housing configuration against the original part before installation.

What It Helps Address

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

Installation Notes

Inspect the intake tract, connector, and housing surfaces before installation. Avoid touching the sensing element with bare hands, and confirm the connector shape, terminal count, and housing style match the original unit. For Hyundai Santa Fe, Hyundai Tucson, and Kia Sorento applications, clean surrounding intake components so the new sensor can read airflow accurately after replacement.

Quality Assurance

Walker Products has supplied fuel system components since 1946 and is an ISO 9001 and IATF 16949 certified manufacturer. The 245-1611 is tested for fit, form, and function, with production verification and on-vehicle validation used to confirm calibration performance.
