Bad mass air flow sensor symptoms ford diesel

MAF) sensor measures the volume of air entering the engine so the Engine Control Unit (ECU) can calculate how much gasoline the fuel injectors should deliver to each cylinder in order to create the proper fuel-air ratio. Sometimes, however, a malfunction in this little instrument can lead to big problems, usually resulting in very poor engine performance.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.

The following are the most commonly experienced drivability problems and a short description of what components may be affected. In each case, these suggestions are assuming the engine is mechanically sound (camshaft, pistons, timing chain or belt, valves, etc). Absolute Pressure Sensor. It's nothing but an electronic vacuum gage.

MAF sensor can cause a wild up/down engine idle speed (say, 0-0rpm). This might be caused by a loose harness connection or by a damaged or contaminated sensing wire.
