When there is imbalance in the fuel and air equation, the fuel economy of your car will surely get compromised. This Is What Bad Fuel Will Do To Your Car: 7 Effects Of Bad Fuel In Your Car 3. In this video, you will learn 5 signs of a bad mass air flow sensor (MAF SENSOR). The mass air flow sensor monitors air intake as it is mixed with fuel prior to being injected into the motor. You might experience stalling, shuddering etc. Hi There, This could potentially cause the car to die when you come to a stop, depending on how bad the problem or signal from the mass air flow sensor is. Once it fails, there would be performance issues for the engine. The mass airflow sensor is a vital component that balance the amount of fuel and air to be used by the engine. If the mass airflow meter is not functioning as it should be, the check engine light will be illuminated. Check engine light:Ī faulty mass airflow sensor is capable of triggering the check engine light. Symptoms of a failing or bad Mass Airflow Sensor 1. When this mass airflow sensor gets bad, it can cause varieties of problems and often times result to poor performance. This information is used to correctly balance and deliver the proper amount of fuel needed by the engine at any point in time. The function of the Mass Airflow Sensor (MAF) is to monitor and report to the Engine Control Unit (ECU) the amount of air entering the engine. I was very surprised how he could get such misleading information from a mechanic.Īll these that happened inspired me to make this post so that others will not end up being a victim of this deception. They could mean that your car has a vacuum leak, blocked intake, torn tubes or hoses in the intake system, or something else entirely. The owner told me he knows what is wrong with the car that the mechanic told him it’s ABS. All these while, I knew what is wrong with the car.ģ Symptoms of a Bad or Failing Ball Joint I had to off the engine and on back at times to get it back to its senses. The most common signs of bad mass air flow sensor (MAF) in Chevy Silverado 2500 HD are loss of power or slow acceleration, engine hesitation or jerking during acceleration, erratic idling, misfires, poor exhaust emission values and sometimes black smoke comes out of the tailpipe. After the checks, I started the car and bleeped the throttle and I also noticed the tachometer couldn’t go more than 5000 RPM it wouldn’t even go beyond 2000 RPM some of the time I was doing these checks. I pulled over to check what the problem might be. A mass airflow sensor (MAS) determines the mass of air entering a vehicles fuel injection engine, and passes that data to the Engine Control Unit, or ECU. The car jerked stalled, jerked repeatedly until I let loose the gas pedal and it came back to normalcy. Whenever it wanted to exceed 3500 RPM, the car will start coughing and wouldn’t pick up the corresponding pressure applied to the gas pedal. The car couldn’t comfortably exceed 3500 RPM as recorded in the tachometer. I noticed a very serious problem as I was driving. Few weeks ago, I went to drive down a friend’s car from Abuja to Minna (Niger State).
