Mass Air Flow (MAF) sensor measures the amount of air by weight through changing voltages or frequencies
MAF Sensor sends information collected to the onboard computer
The computer uses this and other inputs to calculate the correct amount of fuel delivered
Symptoms of failure MAF include poor starting, engine surging, engine stalling, a check engine light, and no-start conditions. Sensors are non-serviceable, replace sensors that are non-functional
