September 2018 marked the 11-year anniversary of mandatory tire pressure monitoring systems (TPMS) for all light vehicles sold in the U.S. During these past 11 years, more than 164 million vehicles have been equipped with TPMS. If you multiply that number by four, it means that there are more than 656 million tire pressure sensors that will need replacement at some point.
TPMS and keyless entry can be difficult to understand because these systems rely on transmitting, receiving and decoding radio waves. You can see wires connecting modules and components, but seeing radio signals takes a little faith in science.
It is that time of year again when the affects of road salt, deicers and potholes start to take their toll on vehicles. The latest victims of the salt belt are TPMS sensors and valve stems. The corrosion we are all most familiar with is that which affects steel, iron’s most common alloy. While just the presence of oxygen in the air, along with some moisture, is enough for something made of steel to begin to corrode, most of the time it is accelerated by some other environmental factor, which causes the most problems.
