Tire pressure sensors can be purchased directly from the car manufacturer or their authorized dealerships. In addition, most major auto parts stores have them in stock or on order.
A tire pressure sensor is located within the tire. The sensor then provides information to the Tire Pressure Monitoring System and informs the driver when the pressure falls below a certain level.
You can purchase a tire pressure monitor from stores such as Auto Zone. Alternatively, you can purchase these monitors online from retailers such as Amazon.
If it is not going off when the tire is filled to the proper tire pressure i would say its the sensor but you would have to get a mechanic to figure out witch one it is. the sensor is inside the tire wrapped around the rim
Yes. The light means that one of the tires is not reading correctly. Either from improper pressure or a sensor problem.
If you are referring to the tire pressure sensor, the answer is yes. One sensor is located inside each wheel. Actually when you look at the valve stem, that stem is part of the sensor. You must remove the tire from the wheel to replace the sensor. Extreme care must be used when installing a tire on a wheel with a tire pressure sensor. They are very easily damaged. If you suspect is is bad, I suggest you visit you local GM dealer. They have a tool that can scan the sensor and detect if it is good or bad without removing it.
Adjust the air pressure in the soft tire to the correct pressure and check the rest. A short drive will reset the light unless you have a fauly tire pressure sensor in one of the tires, then in that case the faulty sensor would have to be replaced by a garage equipped to do tires.
Adjust tire pressure and drive it. The light should reset itself after a short drive unless the pressure sensor unit in one of the tires is bad.
It is the sensor for the tire pressure. It comes on when the air pressure in one of your tires is low.
It means you either have a bad tire pressure monitor sensor at one of the wheels (if it flashes several times before staying lit) or one tire or more has the wrong air pressure in it (you are getting a flat, for example).
If all tires are inflated to 36 psi and the light is still on, you have a sensor issue and will have to take in for service. The dealer has a special tool that can communicate with each sensor (one in each tire) to find the bad one.
If the tire pressure is correct, the sensor should turn off by itself after a brief drive. It will not turn off if the battery is bad in one of the sensors mounted inside the wheel or there is some other problem with the sensor.
Chances are you have a sensor in one of the tires that is broken if you take it in they can attempt to program it. If that fails they can tell you what tire is not working and you can replace the sensor in it. They are not cheap 70-90$ and from what I understand the system is mandatory now so you can not even disable it.
