Symptoms of mass air flow sensor problems

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 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. The faulty mass airflow sensor and how to fix the problem written by: nandy A vehicles MAF or mass airflow sensor, is the element that measures the density and flow of the air passing in to the combustion section.It assists the vehicles computer activate the air ratio to fuel.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.

How to tell you got a bad MAF

If you suspect a MAF sensor problem, scan for any fault codes. A MAF problem should (but does not always) set a fault code. Mass Air Flow Sensor May Cause Driveability Issues on Nissan SentraThe mass air flow (MAF) sensor can fail, causing various drivability problems. Our technicians remind us that proper diagnoses should be performed to confirm the cause of any driveability concerns.

The reader wanted to know both how the technician diagnosed the problem so quickly and how he could test his other Corvettes for the same issue.MAF BasicsThere are a number of seemingly unrelated fault codes and driveability problems that can be attributed to a misreading MAF (that is, one that is under- or over-reporting the amount of air entering the engine). MAF sensor problems on Fords have been cleaning it. Now, the symptoms that accompany a dirty (contaminated) Ford MAF sensor are not that harsh or noticeable on engine performance (of course this is not an absolute truth).
