Mass Air Flow (MAF) Sensors & Meters

Browse replacement Mass Air Flow (MAF) Sensors and Air Flow Meters at AH Car Parts. Positioned between the air filter box and throttle body, our hot-wire and hot-film MAF sensors accurately measure intake air volume so your ECU can calculate the exact fuel delivery needed β€” backed by a full 1-Year Warranty.

What is a Mass Air Flow (MAF) Sensor?

The MAF sensor measures the mass rate of air entering the engine's intake tract. Utilizing an internal heated film or wire element, it relays frequency or voltage signals to the ECU to dynamically balance the air-fuel ratio for clean, efficient combustion.

Why Do MAF Sensors Fail?

Dirt, oil buildup from aftermarket air filters, airborne debris, and carbon contamination coat the internal sensing element. Over time, this thermal insulation prevents the sensor from reading airflow changes accurately, causing rich or lean running conditions.

Symptoms of a Faulty MAF Sensor

Common symptoms include engine hesitation, severe lack of acceleration, rough idling, stalling shortly after starting, poor fuel economy, or diagnostic fault codes such as P0100, P0101, P0102, P0103, or P0104.
