AMS button in a car is one of the function buttons of the onboard audio system. Here is some introduction about the AMS button: 1. Usage: When the audio system is in radio mode, holding this button for more than 2 seconds will automatically save the currently tuned radio station in the 1-6 preset stations of the audio system. If the audio system is in MP3 mode, pressing this button will allow you to select the MP3 menu. 2. Related buttons: The car audio system also has many commonly used buttons. For example, the PWR button, a light press of this button can be used to start the audio system, and pressing the button for more than 1 second will turn off the audio system. Another example is the MUT button, pressing this button will directly mute the audio system when it is in working state. Another button is the BNAD button, which is used to switch the radio band, allowing the radio to switch from FM band to AM band.
As a friend who has been driving for over a decade, when we talk about AMS, it actually refers to the Air Mass Sensor, which is installed on the intake pipe and specifically measures the amount of air drawn into the engine. This is crucial for fuel injection—the computer uses this data to adjust the fuel quantity, making combustion more efficient. I've seen many car enthusiasts complain about sudden increases in fuel consumption or lack of acceleration, and upon inspection, it's often due to the AMS being clogged, dirty, or broken, especially after driving in dusty areas. For regular maintenance, I recommend removing it for cleaning or using compressed air to blow it out, which can prevent malfunctions. If the problem is severe, it needs to be replaced. Remember, if it fails, the engine light will come on—don't ignore it, as it not only wastes fuel but also damages the engine. In short, this small component plays a big role, and regular checks can save you a lot of money.
Speaking from my experience with ordinary family cars, let me talk about the AMS. This thing is called the Air Mass Sensor, responsible for detecting the engine's air intake. When I first bought my car, I didn't understand it, but later I found that when it fails, the car idles roughly, accelerates sluggishly, and fuel consumption skyrockets, which is heartbreaking. Simply put, it's like an accountant, calculating how much air comes in and directing the computer to inject fuel. When it breaks, repairs aren't expensive—just replace it for two or three hundred yuan, but you need to go to a professional shop for diagnosis. For daily maintenance, I make it a habit to check the air filter and whether it's clogged with dust every 5,000 kilometers. I also take a look after highway driving to avoid debris getting stuck. This is also good for environmental emissions—don't underestimate it. Keeping it in good condition can extend the engine's lifespan. When driving, pay attention to any unusual engine sounds or warning lights and address them promptly.
