Symptoms of a failing Mass Air Flow Sensor
Poor engine performance
Let’s see how much attention you’ve been paying. 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. So, what exactly do you think happens when the MAF sensor kicks the bucket, and the car can’t make those adjustments? If you guessed that it’s no longer going to get the most out of its engine production, then congratulations, you’re totally right. When you want to giddy up, but notice a lack of oomph, that could be a result of the air flow failing. If the MAF is struggling, the readings may be off, and it won’t contribute to the mechanical symphony as it’s supposed to. It will also negatively impact your fuel efficiency.
Check Engine Light
Now I know you tend not to pay attention to the lights in your dashboard, but it’s never too late to start. The warning lights are there for a reason and they’re positioned right in front of your line of sight, so you notice them. If you have a failing air flow sensor, your check engine light, which is kind of like a catch-all like, may illuminate.
Rough idle or stalling
Here’s the deal with your mass airflow sensor. If it’s struggling, your car will have some performance issues. But if the air sensor fully kicks the bucket? Well, the car might idle rough and eventually stall. You might first notice this because your car will stall repeatedly, like when you tried to learn how to drive a stick shift. It’s weird. And slightly embarrassing.
How urgent is an MAF Sensor replacement?
Much of the time it’s possible to keep on chugging along with a bad air sensor. You won’t really be unsafe doing so. But you’ll notice that you won’t be able to get the same performance out of your car that you used to, and that should bother you. You’ll also notice changes in your fuel economy.
And look, as much as you might take the ignorance is bliss route with these things, these issues don’t magically go away. Instead, they get worse, and as they get worse, they burn a bigger hole in your pocket. Therefore, replace the faulty mass airflow sensor.
