Mass airflow sensor problems can cause a variety of symptoms from the annoying to the must repair. We'll discuss these in-depth on this page. A bad mass air flow sensor in a vehicle makes starting difficult and affects the performance of the engine because he engine-control unit uses data from the MAF sensor to balance the fuel ratio the injectors deliver to the engine. A bad sensor returns a significantly different temperature than that of the engine coolant when read using a scan tool set to temperature.There are a number of things on a car that are built to regulate the amount of air and fuel that get mixed.
The mass airflow sensor is one of the most important of these sensors due to the job that it performs. Mass Air Flow Sensor May Cause Driveability Issues on Nissan SentraThe mass air flow (MAF) sensor can fail, causing various drivability problems.
