Mass Air Flow Meter Information

The Mass Air Flow Meter is the device used in many fueli njected engines to measure the amount of air entering the engine so the onboard computer (ECU) can calculate the correct air/fuel mixture ratio to enter the combustion chambers. Located ahead of the throttle body, the MAF sensor uses a heated wire or filament/film to measure the air flow.

Air Flow Meters are also known as:

• 'Air Mass Meter'
• 'MAF'
• 'Air Mass Sensor'
• 'Mass Air Flow Sensor'
• 'Air Flow Meter'
• 'Air Mass Meter'
• 'AFM'

Faulty Mass Air Flow Meter Symptoms:

• Unsteady Idle AKA "hunting" (car revving up by around 1000rpm itself then dropping back down
• Reduced drivability, cutting out when the engine speed drops. e.g. approaching bends
• Loss of power, turbo lag on turbo applications
• Excessive black smoke on diesel applications
• Reduced fuel economy and lumpy running
• Can feel like you're hitting a rev limiter too early

Typically air flow sensors can go faulty every 40,000 miles,this is due them getting clogged up with dirt within the induction system. Using general cleaning equipment such as carburettor and throttle body cleaner for maintenance will shorten the life of the sensor.
