What can cause a MAF sensor to malfunction?
Often you can narrow down diagnosis using the set trouble code. However, when the MAF sensor malfunctions some faults will actually be symptoms of the root cause. Take a P0102 for instance, which stands for low air volume or input signal to the computer. It can be a wiring issue, problems with the sensor itself or an actual air flow issue.
What happens if the mass air flow sensor is bad?
As the mass air flow sensor is directly linked with the engine, any issue can result in disruptive performance. Here is a more detailed list of the most common signs of a bad MAF sensor: The Engine control unit is full-time monitoring all the sensors in the car engine to ensure that everything is OK.
How much does it cost to replace a MAF sensor?
MAF Sensor Replacement Cost. A Mass Air Flow Sensor is not so cheap but it is not very expensive either. You could get one for $120 – $300 to which you should add labor costs of $80 – $100. Therefore, on average you are expected to pay $200 to $400 in total for a mass air flow sensor replacement.
What does the MAF sensor on a Ford Focus Do?
A MAF sensor measures the density of the air entering the intake manifold. It passes this information onto your Focus’s ECU. The ECU uses this information along with other sensor data to control the amount of fuel that enters the combustion chamber. If you do determine that you need a new mass airflow sensor, they aren’t too expensive.
What are the symptoms of a bad MAF sensor?
There are several symptoms of a bad MAF sensor, and not all of them are immediately obvious: Illuminated Check Engine Light: Performance and circuit diagnostic trouble codes may refer directly to the MAF sensor, but fuel trim and misfire codes can also be linked to the MAF sensor.

What does trouble code p0100 mean on MAF sensor?
Open-circuited or short-circuited MAF sensors usually set a trouble code, most frequently P0102 or P0103 (low input and high input, respectively). P0100 is a nonspecific MAF sensor circuit fault, while P0104 indicates an intermittent circuit failure. Checking scan data is a vital first step toward successful diagnosis of any of these codes.
