Breathe New Life into Your Engine (MAF sensor replacement)

August 15, 2021

If you’ve noticed your vehicle is hard to start, stalling, or has lost power, the culprit may be a part with an odd name: the MAF sensor.  You may have never even heard of a MAF sensor, but it’s important that it be working correctly, or you may be experiencing some fairly significant engine issues.

All vehicles bring in air and direct it through an air filter before it goes into your engine, where it mixes with fuel to provide power to get you going. There’s a tube-like device with a sensor inside it that measures how much of that mass of air is passing through. That’s why it’s called a mass air flow sensor, or MAF sensor.  If the MAF sensor isn’t working right, the engine’s computer can’t figure out the right amount of fuel to mix with it, and your engine may hesitate or stall.  Sometimes this will cause your Check Engine Light to come on, and any time it does that, make sure you have your vehicle checked by a professional, so you’ll know what’s going on.

When you take your vehicle into your service facility, a technician will thoroughly check the system to see just where the problems are.  If your air filter is dirty, your MAF sensor may get dirty too, which might be causing the problems.  You may find your fuel economy isn’t what it used to be either.

There are other things that can cause the same symptoms, too, such as a leak in a vacuum hose. It’s also possible that the electrical connector between the MAF sensor and the engine has broken. 

The technician can use electronic diagnostic equipment to help pinpoint the exact problem or problems, replace worn parts, and test drive your vehicle to make sure it’s working correctly.

It’s also a good idea to make sure your air filter is changed regularly. A dirty air filter can contribute to a MAF sensor failure. One of the big benefits of having your vehicle regularly maintained at one facility, is they know your vehicle. So, they keep track of which of your vehicle’s parts should be periodically replaced before problems develop. 

If you keep clean air heading into your engine, it can help your engine work efficiently, and with the power it was engineered to deliver. Isn’t that a breath of fresh air?
