How does the MAF sensor work in a car?
The engine computer uses the MAF sensor signal to determine how much fuel needs to be injected to meet the proper air-fuel ratio. The MAF sensor signal is also used to calculate engine load, meaning it can cause trouble for the traction control system, or change the automatic shifting pattern in applicable vehicles.
When do you have to clean the MAF sensor?
You have to clean the MAF if it’s dirty. If the wire is just dirty, caused by dirt from the oil or spider webs, cleaning it will solve the issue. 2. Engine continuously runs rich or lean
What is the code for mass air flow sensor?
This Code’s full read out is: P0101 – Mass Air Flow Sensor Circuit Range/Performance. The engine computer uses the MAF sensor signal to determine how much fuel needs to be injected to meet the proper air-fuel ratio.
What is the range of a split second MAF sensor?
They have internal regulation that insures that the measurement is accurate as battery voltage changes. Most MAF sensors used in automotive applications have an output signal range of 0-5 V, 0-5 mA or 0-10 kHz. The sensors used in Split Second MAF kits produce a nominal 0-5 V output signal.

What should I do if I Change my MAF?
As others have stated… After you changed the MAF you needed to clear your code… Without a tool you simply disconnect the battery for a few minutes. Then test the vehicle. IF you get another MAF code with the new sensor and after batt disconnect… Your air filter is clogged. If the new MAF doesnt detect proper airflow it will register as a bad MAF.
It gauges the volume of air entering the engine and sends that information to the Engine Control Unit (ECU). Based on that piece of information, the ECU determines the amount of gas that fuel injectors need to send to each of the cylinders.
What should I use to clean my MAF sensor?
If the sensor wires are dirty, use an electronics spray cleaner to clean them with. This in itself may solve your problem. I don’t recommend using carb or brake clean spray. These solvents can damage the sensor. Also, don’t attempt to physically clean the sensor with anything. You’ll find all autopart stores sell the correct cleaning spray.
What to do if your car engine is sputtering?
The seals and gaskets prevent exhaust gases and oil from finding their way to the combustion chambers. When these fail, you will start experiencing a sputtering engine. Further seal damage will eventually lead to the complete destruction of the exhaust manifold. The solution to this is to simply replace the seals and gasket if you find any leaks.
What happens if you leave the mass airflow sensor Unplugged?
Q: Car runs with the mass airflow sensor unplugged. If you plug it in it will die if the car is running. If you unplug the mass air flow sensor the car will start. If you try to plug it in while it’s running the car will die. My car has 90000 miles. My car has an automatic transmission. This is a sure sign of a shorted mass airflow sensor.
Can a car run without the mass air flow sensor?
The mass airflow sensor is a key sensor in your car. Your car has a lot of sensors, and this is just one that helps your car run properly. That brings up the question of can your car run without the mass air flow sensor? In this article, we will look at what happens when you disconnect the mass airflow sensor.
