Jan 15, 2018· keeping the mass air flow sensor precise The precision that the MAF sensor is expected to deliver at makes it a powerful but delicate device; it can be easily contaminated by dirt, debris and oil. Contamination can occur as early as 18,000 to 25,000 miles, depending on the model of the vehicle.
Acceleration problems can indicate a problem with the mass airflow sensor The Air Fuel Ratio is Too Rich or Lean When the MAF sensor isn’t working properly, the amount of fuel within an engine’s combustion cylinders will either be too much or too little in comparison with the amount of air.
Nov 10, 2018· It’s called a Mass Air Flow Sensor, and Bill explains why it can be a source of many engine watch all our most up to date content, check out our ...
After turning it on, check for the temperature of the IAT sensor. It should be 10°F above or below the ambient temperature of the vehicle. If this is not the case, you may have a problem with the sensor. Shake the IAT sensor connection to the mass air flow sensor, and check to see if there is any difference in reading.
Jan 08, 2016· A MAF sensor that behaves like this will require replacement. Before replacing the sensor, however, the rest of the circuit should be checked for proper operation. If the circuit has an issue, replacing the sensor will not solve your problem. 3. Rough idle or stalls. A completely failed MAF sensor will not send any airflow information to the PCM.
Oct 07, 2020· 7 Symptoms of a Bad Mass Air Flow Sensor Modern electronic engine controls calculate the correct quantity of fuel for a given situation. Several sensors and actuators come into play, such as the mass air fuel (MAF) sensor and fuel injectors, and just as with any other car part, these sensors and actuators can degrade over time.
