The mass air flow sensor (MAF) is a critical component in the intake system of an internal combustion engine. It measures the actual air mass flowing into the engine and transmits this information to the engine control unit. The control unit uses the measured air volume to calculate the exact amount of fuel to ensure an optimal air-fuel mixture.
A correctly functioning air mass sensor ensures:
- better performance development
- lower fuel consumption
- reduced exhaust emissions
If it's defective or dirty, problems such as rough engine running, loss of power, or increased fuel consumption can occur. Modern vehicles often use so-called hot-wire or hot-film air mass sensors, which operate with exceptional precision.
In short, the mass air flow sensor is crucial for clean, efficient and powerful engine control.
