Hot wire air flow sensor
2024-10-29
Hot wire air flow sensors are advanced MAF sensors and are more common,consisting of thermistor , a platinum hot wire and an electronic control circuit.The thermistor is a temperature sensor that measures the air temperature.An electronic control circuit keeps a hot wire at a constant temperature.When the air flows through the hot wire,it cools down.When the temperature difference between the two wires changes,the MAF sensor will automatically increase or decrease the air flow to the hot wire.
Features of Hot Wire Air Flow Sensor:
It has a fast response speed and can respond the changes in air flow in a few milliseconds with high measurement accuracy,small intake resistance, no wear and it can directly measure the mass flow of intake air.
Influence and Solution about Hot Wire Air Flow Sensor:
The surface of the hot wire is easily contaminated by dust in the air,which reduces the heat radiation and affects the accuracy.Errors will occur when the air flow rate is unevenly distributed,engine backfire can easily lead to wire breakage,etc.But please don’t worry if the air flow sensor of your car is dirty, the solution is to purchase the cleaner, open the hood, remove the air flow and spray the cleaner.
Why is it important?
The mass air flow sensor is essential for the optimal operation for car’s internal combustion engine.Based on its air flow measurement, the ECU balances air fuel up.Generally speaking, without a MAF sensor, your car wouldn’t work.
That is why you need to check and maintain properly. Otherwise,MAF sensors are relatively inexpensive to replace.Best yet, you can clean it by yourself.
