How does a hot wire maf sensor work
WebNov 23, 2024 · The hot wire is maintained at a constant temperature in relation to the thermistor by the electronic control circuit if the airflow increases then the hot wire will lose the heat faster and the electronics control circuitry will compensate by sending more current through the wire. WebA bad Bosch hot-wire MAF sensor may be the result of a failed burn-off circuit. Don’t simply replace the sensor; make sure the burn-off is functional. (The purpose of the burn-off is to clean the hot-wire of contaminants after each trip.) Burnoff is usually a key OFF function after engine operation exceeding 2000 rpm.
