Hella Mass Air Flow Sensor MAF

The Hella Mass Air Flow Sensor (MAF), also called an air mass meter or MAF sensor, measures the amount of air entering the engine. It sends that data to the engine control unit (ECU). The ECU uses it to calculate fuel delivery, which supports efficient combustion, smooth running and controlled emissions.

Key Features:

• Measures intake air mass and sends an electrical signal to the engine management system
• Supports correct air-fuel ratio, throttle response and fuel economy
• Made to meet original equipment specifications for fit, form and function
• Hella is a long-time OE supplier of automotive electronics and sensors, so quality standards are high
• Built for consistent, accurate readings over a long service life

Common Symptoms of a Failing MAF Sensor:

• Rough idle or stalling
• Hesitation or loss of power during acceleration
• Poor fuel economy
• Check engine light with air flow or air mass related fault codes

Replacing a worn or contaminated mass air flow sensor can restore proper engine performance and drivability. Select the correct variant for your application from the options on this page.
