Overview

The mass air flow sensor is the ECU's measure of how much air is entering the engine, read across a wide range of ambient temperatures. When it drifts or fails, the fueling math is wrong everywhere: rough idle, hesitation, stalling, worse fuel economy, and usually a check engine light. This AUXITO MAF sensor is built with precision sensing elements for accurate readings and a direct fit for the applications in the table below.

Vehicle fitment & specifications

Features

Accurate airflow readings
Measures the amount and characteristics of air entering the engine and feeds the ECU across a wide range of ambient temperatures, so fueling stays efficient.

Precision components
Built with precision sensing elements and quality components for durability and accurate measurement.

Direct match
Manufactured to match the original sensor's fit and connector.

Fitment check

Listed for the Honda and Acura models, years in the 18-line table above. Honda used more than one MAF variant across these years — the two OE numbers above (37980RNAA01, 37980RC0M01) cover different applications — so compare the number on your original sensor against the list before ordering.

FAQ

What are the signs of a failing MAF sensor?
Rough or unstable idle, hesitation or stalling on acceleration, worse fuel economy, and a check engine light — commonly with airflow-related codes such as P0101. If the light comes back after replacement, the fault is elsewhere and needs diagnosing.

How do I confirm it fits my car?
Match your model and year against the 18-line table, then compare the number on your original sensor against 37980RNAA01 or 37980RC0M01 — the two variants cover different applications.

Do I need to reset anything after installing?
No special reset is usually needed — the ECU relearns its fueling trim over the next drives. If a fault code returns, the cause is elsewhere.

Can I clean it instead of replacing it?
If the element is only contaminated, a MAF-specific cleaner sometimes helps. A sensor with a failed element needs replacement — cleaning does not restore it.

Is the mounting hardware or connector included?
No — the package is the sensor itself. Reuse the original screws and connector.
