How to Test MAF Sensor on Alfa Romeo Twin Spark

In this video we’re going to show you how to test 5 wire mass air flow sensor. As mentioned in the video, you can use the same process to test 6 wire MAF sensor as well. The same procedure can be applied to any car manufacturer or model. If your MAF sensor has 3 wires, that would mean that it doesn’t have intake air temperature sensor implemented, so you would have a constant voltage, ground and a signal wire.
