About TPMS Valve Stem
The TPMS light on your dash is staying on, and you know that this is a tire pressure monitoring system light, but you cannot find any problem with the pressure in any of your tires. In fact, the problem could actually be in the TPMS valve stem itself. When the TPMS valve starts to malfunction, it may not send the correct data to your car's internal computer, which can make the light come on, and stay on, no matter what you do. With a valve stem puller, you can remove the old valve stem and replace it with a new one that is in good working order. In some cases, the valve stem tool comes with the new stem and kit, but this is not always true. Once the new valve stem is in place, it may take driving on the tires for a few minutes for the new stem to communicate the proper data to the internal computer. At this point, the TPMS light should turn back off. Within the vast inventory on eBay, you can find just the right TPMS valve stem to help you return your dash light situation to normal.
