Faulty mass air flow sensor problems broken

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.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. 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.

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. Check engine, oil, power steering, break, and battery warning lights came on. The engine would turn over, but not start.

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).
