How do you know which tire sensor is out?

The easiest way to find out which TPMS sensor has gone bad is to read the trouble codes with an OBD2 Scanner. If your car has a display of each wheel’s tire pressure on the dashboard, you can also check there if some pressure is irrelevant.

How many TPMS sensors does a car have?

Direct TPMS systems consist of 5 main parts: the 4 sensors mounted onto the wheel of each tire (usually near the valve stems) and the indicator in the vehicle’s computer system. Therefore, when it is time for the vehicle’s maintenance, replacing a direct TMPS system will be a bit more costly.

How do I know if my TPMS sensor is not working?

After starting a vehicle, a TPMS icon will turn on for a few seconds; however, if it stays on, it indicates that one or more of the tires on the vehicle are at least 25% below the recommended pressure. If the light flashes for approximately one to two minutes, it indicates there is a malfunction in the TPMS system.

Why wont my tire pressure light go off?

If you’ve inflated your tires to the proper air pressure, but the warning light stays on, you may have a leak or there’s a problem with the TPMS in one or more of your tires.

Can you drive with a bad TPMS sensor?

No, driving with the TPMS Light on is not safe. It means one of your tires is underinflated or overinflated. You can find the proper tire pressure for your car in your owner’s manual, or on a sticker located on the door, trunk, or fuel door.

Can you drive with a bad tire sensor?

It is unsafe to drive with a tire pressure sensor fault because this could mean that one of your tires may be losing air pressure. So, when you do get the tire pressure fault message or icon, it is important to pull over to a nearby gas station to check your tires and re-inflate them if necessary.
