ChawYI Mass Air Flow (MAF) Sensor for Honda & Acura — Direct-Fit 2.4L/1.5L Replacement, OEM Cross-Refs 37980R40A01

ChawYI Mass Air Flow (MAF) Sensor is a direct-fit replacement sensor that measures incoming air to help your Honda or Acura engine run efficiently.

This MAF sensor is designed to match factory fitment for a range of Honda and Acura models from late-2000s to late-2010s. Built to plug into existing harnesses and meet OEM-style specifications, it replaces common part numbers such as 37980-R40-A01 and 37980-R11-A01. The aim is consistent airflow measurement so the engine control unit (ECU) can adjust fuel delivery and ignition timing based on accurate intake readings.

Which vehicles does this ChawYI MAF sensor fit?

The sensor fits many Honda and Acura models that originally used the listed part numbers. Confirm compatibility by matching your vehicle year, engine displacement, and the OEM part number before ordering to ensure a correct match.

• Honda Accord 2008–2012 2.4L
• Honda CR-V 2010–2019 2.4L
• Honda Civic 2012–2016 (including 1.5L Turbo and 2.4L variants where applicable)
• Honda Crosstour 2012–2015 2.4L
• Acura ILX, NSX, TSX models listed 2009–2020 ranges

How does this MAF sensor affect engine performance?

A correctly functioning MAF sensor supplies the ECU with precise airflow data so it can calculate fuel injection and timing more accurately. When the sensor measures airflow reliably, the engine runs closer to its intended air/fuel ratio under varying loads and speeds.

• Improved fuel metering when readings are accurate
• Smoother idle and throttle response when installed properly
• Helps maintain reasonable emissions and drivability

What are the key replacement and compatibility details I should check?

Before purchasing, verify your vehicle’s original part number or confirm fitment using year, make, model and engine size. This ChawYI unit lists several cross-references and aftermarket numbers to help confirm compatibility with your application.

• Cross-references include 37980-R40-A01 and 37980-R11-A01
• Also compatible with many aftermarket codes like MAS0360, MA245, SU14783
• Check connector shape and mounting points against your factory sensor

What should I expect when installing this replacement sensor?

Installation is typically straightforward for anyone comfortable with basic engine bay tasks: unplug the wiring harness, remove the old sensor, and secure the new sensor in place. After installation, the vehicle may need a short drive cycle for the ECU to adapt to the new sensor readings.

• Direct-fit design for factory mounting locations and connector types
• No additional programming usually required; ECU relearns quickly
• Inspect air intake boots and clamps for proper sealing during install

Who is this for: This ChawYI MAF sensor is aimed at owners and mechanics servicing Honda and Acura vehicles in the listed years and engine sizes who need a reliable, plug-and-play replacement. It suits DIYers replacing a failing sensor, fleet technicians maintaining multiple vehicles, and anyone verifying cross-referenced part numbers for a correct, cost-effective swap. If your vehicle shows diagnostic trouble codes related to mass airflow, or you’ve confirmed a faulty unit, this replacement offers an OEM-style fit and measurement technology to restore proper intake sensing.
