Typical MAF sensor problems
Problems with the MAF sensor are typical for many vehicles and the sensor usually gets damaged or contaminated. When the MAF sensor is dirty or broken, the vehicle still can run. But it would not work efficiently and there is a huge risk of serious mechanical engine damage. Here are some of the typical MAF sensor failure problems:
- ● MAF sensor not sending any airflow data to the ECU
- ● MAF sensor sending faulty information to the ECU
- ● ECU not able to control fuel properly
- ● Not idling or idling roughly engine
- ● Consistently lean or rich condition, etc.
Symptoms of a bad or faulty MAF sensor:
- ● A change in fuel consumption
- ● Hard engine start or turn over
- ● Stalling engine shortly after starting
- ● Engine dragging while under load or idle
- ● Rich or lean idling
- ● Black smoke out of the exhaust pipe
- ● Less power
- ● Poor acceleration
- ● Check Engine or Service Engine Soon lights on

FAQ
1. How do I know that my mass air flow sensor is faulty?
The vehicle indicates errors such as erratic engine operation, reduced performance, increased petrol consumption and engine cutout.
Other causes may be possible why an intact mass airflow sensor may indicate wrong signals:
- Defect exhaust gas recirculation valves
- Leakages in the induction tract
- Blocked air intake filters
- Faulty tank ventilation valves among other things.
Only car garages are capable of conducting distinct fault diagnoses and reading out the error messages.
2. Why is my mass air flow sensor faulty?
Mass airflow sensors are extremely sensitive replacement parts. The hot film meter inside the mass airflow sensor is very susceptible and can be easily contaminated by dirty and oil. This may be due to different reasons. Environmental conditions (rain, splash water…), sand, dust, road salt, vibrations, oil and so on affect the efficient readings of the mass airflow sensor. Oil particles from oil covered sports air filters may damage the sensor. A faulty or damaged mass airflow sensor sends the wrong input signal to the electronic control unit which in turn wrongly activates other components. Regularly replacing the air filters helps to extend the durability of the mass airflow sensor.
3. Why does my car need a mass air flow sensor?
The mass airflow sensor measures the air mass, which flows through the air filter to the engine. The data is then sent to the control unit in order to specify the injection rate of the fuel. The combustion engine requires 14,7 kg of air for the optimal combustion of 1kg of fuel. In order to regulate the correct proportion of fuel and air in any operational condition, the engine control unit requires the exact information concerning the intake of the air mass. The mass airflow sensor plays an integral part in the reduction of exhaust and air supply.
4. What does a mass air flow sensor consist of?
A mass airflow sensor consists of a case which is positioned between the air filter and air pipe. The sensor is either screwed or firmly attached inside the case. The sensor in turn includes a hot film meter and electronics. The sensor measures the air which flows to the engine through the air filter and sends the data to the control unit.
