Potential causes for this trouble code may include:

Possible other driveability symptoms or even no symptoms.

Engine hard start or stalling after it starts.

Malfunction indicator lamp (MIL) illumination (a.k.a.

P0104 Mass or Volume Air Flow "A" Circuit Intermittent.

P0101 Mass or Volume Air Flow "A" Circuit Range/Performance.

Note: Some MAF sensors also incorporate an air temperature sensor, which is another value used by the PCM for optimal engine operation.Ĭlosely related MAF circuit trouble codes include: Is not performing within the normal expected range of the calculated MAF value. The PCM detects that the actual MAF sensor frequency signal This P0100 diagnostic trouble code (DTC) means that there is a detected problem with the Mass Air Flow (MAF) The powertrain control module (PCM) uses that reading along with other sensor parameters to ensure proper fuel delivery at any given time for optimum power and fuel efficiency. The MAF sensor itself only measures a portion of the air entering and that value is used to calculate the total volume and density of air being ingested. The MAF (mass air flow) sensor is a sensor mounted in a vehicle's engine air intake tract downstream from the air filter, and is used to measure the volume and density of air being drawn into the engine. Although generic, the specific repair steps may vary depending on make/model. Brands include but are not limited to Toyota, Nissan, Vauxhall, Mercedes Benz, Mitsubishi, VW, Saturn, Ford, Jeep, Jaguar, Chevy, Infiniti, etc. This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles that have a mass airflow sensor.

If you find yourself needing to replace your MAF sensor, Fiix can send a licensed mechanic to your home or office to perform the replacement for you. The fix for this is a replacement of the MAF sensor. This will prevent your car’s computer from controlling the airflow information properly, causing the mentioned problems. If your MAF sensor fails completely, airflow information will not be sent to your control module. The fix for this problem is as simple as cleaning the hot wire. If you consistently notice these features, chances are your wire is being insulated. If the wire is dirty, for example due to dirt, oil, or even dust, your engine will run lean when in motion, and rich when idling, due to inaccurate readings. Your mass air flow tells your car’s computer information about the air that is used in your engine’s combustion chamber. Your Engine Runs Lean When Working, or Rich When Idling The typical fix for this problem is a replacement of the MAF sensor, however, underlying issues in circuitry may warrant the replacement of associated electronics or the entire engine control system. In extreme cases, symptoms of your engine running lean (link to running lean article) or rich (link to running rich article), however, this will usually only manifest itself in a change in fuel economy, unless there are underlying issues with your engine control system. If your MAF sensor is consistently reporting inaccurate information to your car’s computer (for example, due to deformation of the wire, or damage to the electrical equipment), then your engine will either consistently run lean or rich. Your Engine Consistently Runs Lean or Rich Common signs of a failing MAF sensor include: 1.

Your car uses this number for multiple calculations, which is why keeping your MAF sensor running properly is important. This type of sensor measures the amount of current necessary to maintain the temperature of a wire above 90 degrees, which in turn gives your car’s computer a measure of the mass of the air entering the engine. This is important as it allows your engine to regulate its performance and change the intake of air to keep your engine running in its best condition.īy far, the most common type of MAF sensor is a “hot-wire” MAF sensor. Your Mass Air Flow Sensor (MAF Sensor) is a piece of technology within your engine which tells your car’s computer how much air is entering the engine.
