5 Signs Of A Bad Mass Airflow Sensor

5 SIGNS OF A BAD MASS AIRFLOW SENSOR

Overview

The Mass Air Flow Sensor (MAF) is a critical component in the proper operation of automobile engines. It detects the amount of air that enters the car engine and communicates this information to the engine control module, which controls how much fuel the fuel injectors inject into the engine. Overtime, the MAF sensor can become worn or damaged over time. With the help of reliable auto repair Chamblee mechanic at Wrights Car Care, you can fix these issues in no time.

Lean Or Rich Fuel Mixture

If the MAF does not accurately read the air influx, the engine control module (ECM) may limit the amount of fuel in the combustion chamber, resulting in a lean fuel mixture. In addition, the ECM may increase the amount of fuel in the combustion chamber, resulting in a rich fuel mixture. Your vehicle will struggle to idle on a lean or rich fuel mixture, sputtering and possibly stalling.

Acceleration Hesit

When you press the gas pedal to accelerate the vehicle, you may notice some hesitation as you move forward. This is due to the engine not obtaining a consistent flow of gasoline to meet your acceleration demands. As a result, the acceleration will begin to stutter since the engine lacks an adequate flow of gasoline. This could become a driving hazard while you're driving. You should immediately have your vehicle inspected by a mechanic so that you can repair your sensor and avoid any accidents.

Engine Stalling

if the engine stall unexpectedly shortly after you start driving the vehicle then it you need to restart your engine. If you continue to have engine stalling issues, try to bring your vehicle to a nearby auto mechanic before you can't start your engine at all. If you had hard idling prior to this issue, stalling will prove that you have a defective mass air flow sensor.

Black Smoke From Exhaust Pipe

Black exhaust from extra gasoline is one symptom that your vehicle's MAF is failing. If the MAF is not transmitting accurate measurements to the engine management module, too much fuel may end up in the combustion chamber. Additionally, the extra fuel can jam the catalytic converter.

Difficult To Turn Over

When you turn the key in the ignition and twist it, the engine may be difficult to start or may not start at all. This is comprehensible with a faulty mass air flow sensor because it will result in an insufficient combination of air and gasoline in the internal combustion chamber. If you want the engine to start, you must resolve this issue so that the spark plugs can ignite the proper combination.
