Key Features

  • Brand: SKP
  • Part number: SK2451244
  • Mass air flow sensor for emission control systems
  • Direct-fit coverage across multiple Toyota, Lexus, Subaru, Scion, Suzuki, and Pontiac models
  • Supports accurate airflow input for engine control calculations
  • Fits broad year coverage from 2008-2024 across confirmed applications

Detailed Description

The SKP SK2451244 mass air flow sensor is used to measure incoming air so the engine control system can calculate fuel delivery and operating strategy. It is a practical replacement for vehicles experiencing airflow signal issues on applications such as 2012-2017 Toyota Camry, 2010-2015 Toyota Prius, 2010-2024 Toyota 4Runner, 2016-2024 Lexus IS300, and 2009-2019 Subaru Legacy. The same part number also appears on Lexus NX, RX, GS, ES, RC, and Toyota Highlander, Avalon, Sienna, and RAV4 applications.

What It Helps Address

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

Installation Notes and Tips

Verify the connector style and OE part number before installation. Confirm the exact vehicle application by year, make, and model, especially on vehicles with date-specific coverage such as the 2019 Toyota RAV4 through 11/2018. After installation, clear diagnostic trouble codes and inspect the intake tract for leaks, loose clamps, or contamination that could affect sensor readings.

Quality Assurance

SKP replacement parts are cataloged for direct application matching across confirmed fitments. Part number SK2451244 is listed with multiple OE cross-references for the same vehicle applications, including 222040T020 and 222040V010.
