Mass Air Flow Sensor

The Mass Air Flow Sensor (AF10709-12B1) measures the exact air intake for precise fuel injection control. Replacing it with a Porza-quality unit restores smooth performance, efficiency, and emissions stability.

FAQ

A mass air flow (MAF) sensor is an electronic component that measures the amount and density of air entering the engine. Its function is to send this data to the engine control unit (ECU), which uses it to calculate the correct amount of fuel needed for optimal combustion, performance, and emissions.

Key specifications include sensor type (hot wire or hot film), operating voltage (typically 12V), measurement range, connector type, and compatibility with the vehicle’s ECU. The sensor must provide accurate readings under varying conditions and withstand temperatures typically ranging from -40°C to +120°C.

Replacement is necessary when the sensor becomes faulty, contaminated, or damaged. Common symptoms include rough idling, poor acceleration, increased fuel consumption, reduced engine power, or a check engine light. In some cases, cleaning the sensor may restore performance, but replacement is required if the issue persists.

Porza offers a fit guarantee option where your vehicle details, such as license plate or VIN, are checked against product specifications. This ensures the sensor matches your engine and ECU requirements, reducing the risk of incorrect fitment.

Porza supplies high-quality engine management components with fast delivery across Europe. Customers can order online or choose in-store pickup in the Netherlands, Germany, or Belgium. This allows quick and reliable access to essential parts for both professional workshops and individual users.

If you select the fit guarantee, Porza verifies compatibility before shipment. If the product does not fit or meet expectations, it can be returned according to the return policy. This ensures a reliable and risk-free purchasing experience.
