Mass airflow sensors measure the amount of air by weight through changing voltages or frequencies and sends this information to the onboard computer. The computer uses this and other inputs to calculate the correct amount of fuel delivered. Symptoms of failure include poor starting, engine surging, engine stalling, a check engine light, and no-start conditions. Sensors are non-serviceable, replsensors that are non-functional. Walker Products began supplying the fuel system needs of the automotive industry in 1946.
