In the case of a bad mass air flow sensor, the fuel injection is not correctly calculated by the engine control model or ECM. This measurement is important to estimate how much fuel is required for the ideal air-fuel ratio (AFR).
What is a MAF Sensor?Ī mass air flow (MAF) sensor is a car part that measures the quantity of air mass flow into an engine’s inlet. There are a few symptoms to identify a bad MAF sensor and replace it in time. However, with time and usage, these sensors might degrade. To achieve that, several sensors are assembled including fuel injectors, camshaft position sensors and mass air fuel sensors or MAF. Modern cars are fitted with advanced electronic engine controls that estimate the right amount of fuel to be used in any situation.
