how to fix mass air flow sensor problems

To help you catch this problem early on, here are five of the most common signs of a faulty mass air flow sensor that you can watch out for. If the information is incorrect, then an incorrect amount of fuel will be put into the engine causing it to run either too lean or too rich. Remember, the engine control unit needs the correct mass air flow information to know how much fuel to put into the engine cylinders. This will jeopardize the entire internal combustion process because the engine won’t receive the proper amount of fuel from the injectors. If your mass air flow sensor ever goes bad or malfunctions for some reason, it will send the wrong information about the airflow mass to the engine control unit.

This balances the air and fuel ratio to promote successful combustion.

Once the air flow mass is calculated, the sensor sends this information to the engine control module.įrom there, the unit can correctly tell the fuel injectors how much fuel to inject into the engine cylinders. When air from the outside enters the engine, the mass air flow sensor detects the mass of this air.
