With this action, the voltage output should be stable. Using a wrench, tap the MAF sensor softly. With this, you should have about 0.5 to 0.7 volts meter but it might higher on some vehicle model. Now, start the engine and let the idling begin.

If you are using an automatic car, you need to set it to Park while you should set it to neutral with a manual vehicle. The two leads should be far apart from the engine compartments. Then black probe the ground wire which is usually with the negative sign with a meters black lead and also the sensor signor wire, the one with the positive sign with the meters red lead. To test the mass sensor, first thing you need to do is to put off the ignition switch and then plug the MAF electrical connector. How to test the voltage signal of your MAF sensor If you are confused, you can always visit the manual of your car. For a high-frequency type, you can use the voltmeter while you can use a digital multimeter for a low-frequency type. The tool you use depends on the type of sensor your vehicle is using. As you are performing the tests, you will have to use a voltmeter or multimeter to keep checking for the voltage signal. There are different ways you can test your MAF sensors. Some other symptoms you need to look for are poor fuel economy, hard or no starting, low engine power, erratic performance, and engine running in fail-safe mode. The mechanic will run it for a complete diagnosis and tell you if your fears are real. If you believe the MAF sensor is faulty, your vehicle needs to be taken it to the mechanic immediately. These are some of the symptoms you need to look out for. A faulty MAF sensor can cause the engine to drag while it is idle or under load. If you notice this symptom, then you should not overlook it.įurthermore, when you are accelerating and you notice that the car is hesitating or suddenly starts jerking, the mass airflow sensor might be having some problems.Īnother sign is if your vehicles engine starts hiccupping continuously. If you are experiencing any difficulty with starting the engine of your car, then there might be a problem with the MAF sensor.Īnother thing is that your engine might start but just after it does not, it starts stalling. The most common one is that the car’s engine will be so difficult to start or turn over. The symptoms that a fault MAF sensor will show are almost the same as the ones you notice if your car has low fuel pressure. An mass air flow sensor problems can show varying signs or symptoms.Ī damaged or faulty mass air flow sensor can cause problems that a low compression will. As a car owner, the condition of your car should be very important to you. The mass airflow sensor is a very important part of a vehicle’s engine. Mass airflow sensor symptoms (mass air flow sensor problems) The common types of mass airflow sensors are the hot frequency, low frequency, and DC voltage. A damaged or faulty air flow sensor can damage the car’s engine and make it perform poorly. It is usually between the intake manifold of the engine and the air filter. It is useful in measuring the mass of air that needs to enter the fuel injection engine. Read article also What Expect When Driving with Mass Airflow Sensor Unplugged What is the mass airflow sensor?Īs written above, the mass sensor is one of the most important components of a car. With these in mind lets begin with meaning of the mass airflow sensor is. In recent cars, the IAT (intake air temperature) sensor is usually in the mass airflow sensor.Īlthough there are different types of airflow sensors, modern cars are usually built with the hot wire air flow sensor. It is useful for measuring the correct amount of air that needs to enter the car engine. It is usually located right in the middle of the engine intake manifold and air filter. The mass sensor or MAF (Mass airflow) sensor is one of the most important components that determine the performance of a car. If the engine does not fail, then its performance will definitely be affected. It can lead to so many problems which might finally result in engine failure. One of the most harmful defects a car could ever develop is a faulty mass airflow sensor. Conclusion on Mass Sensor Problem What is The Mass Air Flow Sensor (How to Calibrate MAF Sensor).
