Symptoms of bad mass airflow sensor ford

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. Our technicians remind us that proper diagnoses should be performed to confirm the cause of any driveability concerns.

How to tell you got a bad MAF

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.In addition to the bad MAF sensor, there may also be a defective ECM or other sensors. Eliminate engine misfiring or backfiring. 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). The check engine lamp can be caused by a wide variety of problems with the engine: you need to read the codes from the computer to get a starting clue as to what the problem is (see Project for details on reading the codes).

It's perfectly safe to continue to drive the car while the CEL light is on, as long as it is not flashing.

How to know if the mass air flow sensor is bad

Next thing to check would be the Mass Airflow Sensor (MAS), which will cause the engine management system to lean out the mixture unduly, if it is bad. You could also have a bad Throttle Position Sensor causing a lean condition, and this is usually checked by substitution.A bad computer sensor can cause many problems. A sensor error code can be misleading.
