Walker 245-1461 Mass Air Flow Sensor

Walker 245-1461 Mass Air Flow Sensor

Walker 245-1461 is a complete assembly mass air flow sensor built for precise air measurement and stable engine management. It is a direct replacement for the 2012 Volvo S60 complete assembly application and is engineered to support accurate fuel trim control, drivability, and emissions performance.

Walker Products designs this Complete Assembly line for buyers who want a sensor and housing solution rather than a sensor-only replacement. The brand’s MAF program uses programmed, tested components and custom-engineered circuit boards, with production verification performed before release. For 2012 Volvo S60 service, this part number 245-1461 provides a fitment-specific replacement option.

Key Features

• Complete assembly mass air flow sensor for emission control service
• Black housing with triangle connector shape
• Female connector with pin terminals
• 5-terminal design with 2 mounting holes
• 100% new, not remanufactured
• Programmed and tested for fit, form, and function

Detailed Description

Walker Products Complete Assembly MAF sensors are built to measure incoming air so the engine control system can calculate fuel delivery accurately. This helps maintain proper long-term fuel trim behavior and supports consistent performance across the airflow range. Part number 245-1461 is a fitment-based replacement for the 2012 Volvo S60, and the complete housing format helps address concerns tied to contaminated housings or damaged sensor elements.

Walker’s MAF program includes replacement sensors made with OEM-quality components and production testing in the United States for many high-demand applications. This part cross-references Volvo 31216661 and 314594040 for the same application.

What It Helps Solve

• Check engine light related to mass air flow sensor performance
• Rough idle or unstable engine response
• Hesitation during acceleration
• Incorrect air/fuel measurement causing fuel trim issues
• Driveability problems tied to a contaminated or failing MAF assembly

Installation Notes and Tips

Compatible With 2012 Volvo S60, complete assembly. Confirm the connector shape, terminal count, and mounting points before installation. Handle the sensing element carefully and avoid touching it with bare hands. Inspect the intake tract and connector area for dirt, oil residue, or damage before installing the new assembly.

Quality Assurance

Walker Products has supplied fuel system and engine sensor components since 1946 and is an ISO 9001/IATF 16949 certified manufacturer. The 245-1461 MAF sensor is programmed and tested before release, with on-vehicle verification used to confirm calibration and function.
