Note: Some MAF sensors also incorporate an air temperature sensor, which is. What Are The Symptoms Of A Faulty Mass Air Flow Sensor Signs of a bad MAS sensor may mimic problems such as low vacuum, low compression, or low fuel pressure due to a bad fuel pump. The amperage flow through the resistor changes because the electrical resistance of the resistor is responding to the cooling effects of rapidly moving air. The PCM detects that the actual MAF sensor frequency signal is not performing within the normal expected range of the calculated MAF value. In general, a hot wire MAF sensor produces an input to the PCM when a low-amperage electrical current is passed through a metal-film resistor suspended in the MAF’s air stream.

They have a name for this in the trade, it's called throwing parts at it. This P0100 diagnostic trouble code (DTC) means that there is a detected problem with the Mass Air Flow (MAF) sensor or circuit. Make sure they go through the trouble charts. I suggest you take it back, have them do a wiggle test on the plug and wires. A bad connection or wire in the plug may have worked fine after replacing the sensor, but could be waiting to happen again. He may have never really fixed the problem and it could happen again. The dealer tech may have pulled the code and replaced the part without checking everything he should have.

How to stop car hesitation by cleaning the MAF sensor.

Roboxjclark, you may be in the same boat. How to clean mass air flow sensor in your car DIY with Scotty Kilmer. You may need to use a low impedance multi meter or an oscilloscope to trouble shoot the problem.You will have to see the chart to find out. You will need to follow this trouble chart to find the problem.

They can do this, they have free access to Alldata. Once disassembled, you will be able to carry on to the step cleaning the mass air flow sensor of. To get this done, act gently, but you will just have to disassemble it on both sides of the air duct and disconnect the electrical plug on top of it. All engine codes have an associated trouble chart that must be followed to get to the bottom of the problem.Ĭountry Boy, go back to Auto Zone and have them print this chart for you. After having found the mass air flow sensor of your Buick Encore, you will have to dismantle it. If you get a MAF sensor code or any code for that matter it does not mean that this part is bad.
