Walker 245-2340 Mass Air Flow Sensor

Walker Sensor Only Mass Air Flow Sensor

Walker 245-2340 is a sensor-only mass air flow sensor built for direct replacement on select Hyundai applications. It is a black, 5-terminal unit with a male oblong connector and no housing, making it a focused repair for vehicles that need the sensing element replaced without changing the full assembly.

Compatible With 2012-2016 Hyundai Equus and 2010-2011 Hyundai Azera, this Walker MAF sensor is programmed and tested before release. The sensor-only format is often chosen when the housing and connector area are in good condition and the repair calls for a faster, more economical service path.

Product Details

Walker Products manufactures this MAF sensor with custom engineered circuit boards and production testing to help maintain OE-style fuel trim performance. The Sensor Only product line is designed for applications where replacing the sensing element is sufficient, while still delivering a calibrated airflow signal for the engine management system.

This part cross-references Hyundai OEM 281643M000 for the same application.

What It Helps Fix

• Check engine lights related to mass air flow sensor performance
• Rough idle caused by inaccurate airflow readings
• Hesitation or stumble during acceleration
• Hard starting from incorrect air-fuel calculations
• Fuel trim issues tied to a failing MAF sensor

Installation Notes

Install 245-2340 on the correct Hyundai Equus or Hyundai Azera application listed above and verify the connector, terminal count, and sensor style before replacement.
