The temperature of the surrounding area is measured by a temperature sensor that is linked to the hot wire. A small electrically heated wire (hot wire) is used in a hot-wire mass air flow sensor. How does a hot-wire air flow sensor work?Ī temperature sensor positioned near the hot wire monitors the air’s temperature. How often does a mass air flow sensor need to be replaced?.Can a mass air flow sensor mess up your transmission?.What happens if you drive with a bad mass air flow sensor?.Can you drive with a bad mass air flow sensor?.How much does it cost to replace a mass air flow sensor?.Step 3: Dry and reinstall the mass air flow sensor.How do you clean a dirty mass air flow sensor?.How does a hot-wire air flow sensor work?.
