The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters may cause the MAF to become dirty if the filter is overoiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
Feb 24, 2012· A mass airflow sensor (MAS) determines the mass of air entering a vehicle''s fuel injection engine, and passes that data to the Engine Control Unit, or ECU. The air mass information is necessary for the ECU to correctly balance and deliver the correct amount of fuel to the engine. When a vehicle''s mass airflow sensor is faulty or defective it can cause a variety …
Cars can have either an analog or digital mass air flow sensor. Analog MAF sensors produce a variable voltage output, whereas digital sensors send a frequency output. Both outputs are sent to the engine control module to regulate airfuel mixture and the automatic transmission system. Regardless of the type of MAF, the sensors work similarly.

Feb 22, 2021· The mass airflow sensor is a key sensor in your car. Your car has a lot of sensors, and this is just one that helps your car run properly. That brings up the question of can your car run without the mass air flow sensor? In this article, we will look at what happens when you disconnect the mass airflow sensor.
A sensor out of calibration may rise too quickly in reaction to the rpm. This could cause an acceleration problem. Example 3 A sensor with a dirty sensing wire or not measuring all the air (air leak downstream) may rise too slowly. Example 4 Another approach would be to graph both the TPS and the MAF sensor because they should essentially produce a
