We provide comprehensive auto mechanic services in the Baltimore area. If your vehicle is showing signs of mass air flow sensor failure in Baltimore, contact Hollenshade’s today.

A fault mass air flow sensor might be sending inaccurate information to the powertrain control module (PCM), which can cause the vehicle to burn through fuel much more quickly than it should. If you’ve noticed your car suddenly needs more fuel than usual, this could be a sign of a serious issue. If you are experiencing this, you should take your car to an auto repair shop as soon as possible. All vehicles are very sensitive to proper air-fuel mixture and may have difficulty starting if it is thrown off by a bad mass air flow sensor. If you are having trouble starting your car or getting the engine to turn over, the air-fuel mixture might be off balance.

Difficulty Starting/Turning the Engine Over While it can be the result of a few different issues, it could mean your mass air flow sensor is damaged, causing the engine control model to calculate improper fuel injection, resulting in black smoke. Lots of exhaust smoke coming from your car is probably a sign that something is wrong.

A local automotive maintenance professional can get the wires back into working condition for you. This can cause the combustion process to fail, which is often affected by dirty buildup on the wires in the mass air flow sensor. If your car seems to be struggling for power and stalling a lot, it may be getting too much air in the engine and too little fuel. The result is an incomplete combustion process, which can lead to rough engine running and misfiring. This can either cause the engine to run too lean (too little fuel) or too rich (too much fuel). Without a proper signal from the mass air flow sensor, the powertrain control module (PCM), which manages the engine, transmission, and other systems in your car, won’t know how much fuel the engine needs. Operating a car this way is extremely dangerous, so it is important to have an auto repair expert take a look as soon as possible. This may happen while speeding up on the highway on-ramp or cruising down a street at regular speed. If you are noticing unusual hesitation and/or sudden abnormal jolts of power, this can be a sign of mass air flow sensor problems. It could potentially signal a damaged or faulty mass air flow sensor. Regardless of whether there are any other signs of an issue, you should have your car checked out by your local mechanic if the light comes on. The most common sign of mass air flow sensor failure is a lit-up check engine light.

A bad air flow sensor may show as code B1479 when scanned by an automotive repair specialist. In many vehicles, especially those made by Toyota, flow sensors built into the compressor have a high rate of failure. Even becoming too dirty can cause it to stop working, so it’s important to have a local mechanic take a look if you notice any of the following symptoms in your vehicle’s performance.

This is due to the fact that it is constantly exposed to moving air, which is full of exhaust fumes, debris, and dust. Over time, your mass air flow sensor can degrade and become prone to failure. This can cause a myriad of other problems for your vehicle. A faulty mass air flow sensor can make it difficult or impossible for the engine control module (ECM) to calculate fuel injection correctly. Acceleration requires AFR of up to 12:1, while cruising requires levels as low as 22:1. This is important for calculating the amount of fuel to add to achieve the proper air-fuel ration (AFR), Ideal AFR is 14.7:1 (14.7 lb of air to 1.0 lb. Mass air flow sensors measure the air mass flowing into the engine intake. Both outputs are sent to the engine control module to help regulate air-fuel mixture in the car’s automatic transmission system. Digital sensors send a frequency output, while analog mass air flow sensors produce a variable voltage output. However, there are various types of air flow sensors and all require different maintenance. In some cars, the intake air temperature (IAT) sensor is built into the mass air flow sensor. It is located between the air filter and the engine’s intake manifold. The mass air flow sensor (MAF) is a key component of the electronic fuel injection system in a car.
