The more air that blows past the upstream sensor, the cooler it is when compared to the downstream sensor. Thus, the change in temperature (ΔT) between the upstream and downstream temperature sensor is proportional to the amount (and direction) of air mass flowing over the membrane. A thin film MAF can also detect a reverse flow of air.

8 Symptoms Of A Bad MAF Sensor ( Replacement Cost)
