So, the sensor detects how much air is making its way to the engine, so that the vehicle can make adjustments to the amount of air and get the most out of its engine production. Let’s see how much attention you’ve been paying. Symptoms of a failing Mass Air Flow Sensor They’re also not fixable, so one must remove and replace a broken sensor. But, like all things in your car, they’re not indestructible. The mass air flow sensor is always going to be located in line with the intake system, and there’s good news: Despite being in use every time you drive, the sensor is pretty durable, and don’t die often. That thinking part is what the MAFs sensor does for your car. When’s the last time you thought about breathing? Are you consciously controlling your breath right now? Whoops.

Here, let’s put this another way to make it practical. There are a lot of different car components that factor into the engine, and many of them rely on accurate data from the sensor. That’s as true for your car as it is for your body.īased on the readings from the mass air flow sensor, the engine makes appropriate changes to its parts to make the drive as efficient and productive as possible. The energy we put in impacts the power we get out. With the wrong fuel ratio, your car runs like you do that time you tried to run five miles after pounding a meatball sub and not hydrating. With the right air to fuel ratio, the car runs beautifully. Your car’s engine relies on a proper ratio of air to fuel. Yes, the mass air flow sensor literally is a sensor for the amount off air flowing through your vehicle. The MAF sensors monitor how much air is making its way to the engine. So, you can keep calling it that if it makes you feel better. The very first thing that we're going to do is to make sure that the pink with black stripe (PNK/BLK) wire of the MAF sensor connector has power when you turn the key on.Okay, let’s start with the basics: Yes, “MAF” sounds super badass. TEST 1: Making Sure The MAF Sensor Is Getting Power Lack of power when you accelerate under load.A heavier than usual exhaust smell or black smoke coming out of the tailpipe.Although by no means a complete list, you'll see one or more of the following: P0103: Mass Air Flow (MAF) Sensor Circuit High Input.īesides a MAF sensor trouble code, you're also going to see a few other symptoms.P0102: Mass Air Flow (MAF) Sensor Circuit Low Input.P0101: Mass Air Flow (MAF) Sensor Circuit Range/Performance Problem.P0100: Mass Air Flow (MAF) Sensor Circuit Malfunction.You're going to see one of the following trouble codes:

Since the MAF sensor is connected directly to the fuel injection computer, when this bad boy fails the computer is going to set a MAF trouble code and light up the check engine light on your Chevy Malibu's instrument cluster. It plays a critical role in helping the fuel injection computer find out how much air is entering the engine as the engine runs. The mass airflow sensor is a key component of the fuel injection system on your 3.5L V6 Chevy Malibu.
