TPMS stands for Tire Pressure Monitoring Systems. They’re sensors that are typically installed in cars to monitor the pressure of your tires. If the pressure gets too low, the system will notify you so you can take action. In most cases, TPMS is a mandatory safety feature. However, some drivers choose to disable TPMS in order to save a few pounds or because they don’t trust how it works. If you choose to disable TPMS, make sure you understand the consequences. In most cases, this will result in your car not passing an inspection. Here are five things you need to know if you decide to go this route.
What is a Tpms Light and What Does It Mean?
A Tpms light on a car indicates that the system is not working properly. This could mean that there is a problem with one of the sensors, or the wiring to the sensor may be damaged. If the light is always on, it might mean that there is an issue with one of the pressure sensors in the system. If only certain tires are displaying a Tpms light, it might indicate that one or more of those sensors are not functioning properly.
How to Reset a Tpms Light
If your car has a TPMS light on, you might be wondering how to reset it. There are a few ways to do this depending on the make and model of your car. Most cars have a button or lever that you can push to reset the light.
If you don’t know how to get to the TPMS reset button or lever, you can usually find information about it on your car’s owner’s manual. If none of these options work, you may need to take your car in for service.
How to Test Your Tpms System
Testing your TPMS system is an important part of maintaining proper car function and ensuring that you pass inspection. The following are some easy steps to test your TPMS system:
1. Pull up to a stop and press the brakes firmly while simultaneously turning the wheel to the left or right, as close to the limit as possible. A flashing light on your dashboard should indicate when the TPMS is activated.
2. Check for a “TPMS” light on your instrument cluster. If the light is off, press and hold in the brake pedal until the light comes on, then release it. If it does not come on after pressing and holding in the brake pedal for about two seconds, your TPMS system may need service or may be defective.
3. Double-check whether your car’s parking sensors are operational by pressing and holding in both front brake pedals at once while pulling up to a stop next to a curb or other obstruction. If two green lights appear on the dash within two seconds of each other, the sensors are working properly; if one light appears after multiple tries, check that all wiring connections from sensor to computer are securely made and sealed (see our How To Fix A Broken Parking Sensor guide).
Conclusion
If your car has a TPMS light on, it is likely that the system needs to be replaced. A TPMS (tire pressure monitoring system) monitors the pressure in your tires and sends an alert to your car’s computer if the pressure goes too low or high. If you have a TPMS light on, it means that one or more of your tires is not measuring correctly and needs to be replaced. Depending on the severity of the issue, repairing or replacing the tire may be the best option.
