Do you need a mass air flow sensor in your car?
Yes, a Mass Air Flow (MAF) sensor is crucial for modern gasoline-powered cars with electronic fuel injection. It measures the amount of air entering the engine and this information is essential for the car's computer (Engine Control Unit or ECU) to calculate the correct amount of fuel to inject. Without a functioning MAF sensor, the engine's air-fuel mixture will be incorrect, leading to poor performance, reduced fuel economy, and potentially engine damage.
