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.
