Tire pressure sensors are essential for keeping your car on the road and safe. In this article, we’ll take a look at how these sensors work and what you can do to keep them in good condition.
What Are Tire Pressure Sensors?
A tire pressure sensor is a device that measures the air pressure in a tire. The sensor sends a signal to the car’s computer, which then displays the pressure on the dashboard. This is important because overinflating a tire can cause it to burst or lose air, which can lead to a dangerous situation.
There are two types of sensors: digital and analog. Digital sensors use microprocessors to interact with the car’s computer, while analog sensors use mechanical gauges. The advantage of digital sensors is that they are more accurate, but the disadvantage is that they can be more difficult to maintain. Analog sensors are cheaper to install and maintain, but they may not be as accurate.
How Does a Tire Pressure Sensor Work?
A tire pressure sensor is a small, electronic device that is installed on the sidewall of a tire. It measures the pressure inside the tire and sends this information to the vehicle’s control module.
The control module uses this information to maintain a safe tire pressure. If the tire pressure becomes too low, the control module will send a warning signal to the driver. In some cases, the control module will automatically lower the car’s air pressure.
Tire pressure sensors are very important safety devices. By monitoring tire pressure, they can help prevent blowouts and save lives.
What Are the Different Types of Tire Pressure Sensors?
There are three primary types of tire pressure sensors: digital, mechanical and pyroelectric.
Digital pressure sensors use a digital readout to show the pressure in psi. This is the most common type of sensor and is found on most modern cars.
Mechanical pressure sensors use a vane or lever to measure the air pressure and send a signal to the car’s computer. These sensors are less common, but can be more accurate than digital sensors.
Pyroelectric sensors use an electric current to measure the air pressure and send a signal to the car’s computer. These sensors are rare, but are considered more accurate than mechanical sensors.
How to Check Your Tire Pressure
If you have a car, you likely have a tire pressure sensor. Tire pressure sensors are small devices that use air pressure to detect when your tires are inflated. When the pressure in your tires falls below the sensor’s set point, the sensor triggers an alert and your car will tell you how low your tire pressure is.
To check your tire pressure, first make sure you have a tire pressure sensor. Most automakers include them as standard equipment on newer cars. Next, find the correct inflation level for your tires:
Inflate your tires to the manufacturer’s recommended level (usually 80-90 psi).
Then press the “Tire Pressure” button on your car’s dashboard. Your car will tell you how low your tire pressure is and display a warning message if it falls below the recommended level.
When To Replace a Tire Pressure Sensor
A tire pressure sensor is a monitoring device that detects the air pressure in a tire and activates warning lights and sounds on your car’s dashboard when the pressure inside the tire falls below a certain level.
The sensor usually resides in the valve stem of the tire and reads the air pressure every time you rotate it. If the reading ever falls below the preset level, your car will light up its warning systems.
Getting Your Tire Pressure Sensor Replaced
When is it time to replace your tire pressure sensor? That answer varies depending on a few things, such as how much use the sensor has seen, mileage, and type of tire. However, typically speaking, you’ll want to replace your sensor every 7,500 miles for standard tires or every 4 years for premium tires.
If You’re Not Sure When Your Sensor Needs To Be Replaced
If you’re not sure when your sensor needs to be replaced, or if you just want to be safe, you can check for a “replace soon” message from your mechanic. This will let you know that it’s time for a new sensor and give you an approximate date of when it should be replaced.
