For this reason, anytime you remove a tire from the wheel, you should replace the valve’s “service kit.” A plastic sealing valve cap should be securely tightened to prevent valve damage and galvanic corrosion. It’s also exposed to various weather conditions. The valve stem is most vulnerable to damage because it lives outside of the rim and comes in contact with all of the salt and dirt from the roads. On clamp-in valve stems, a rubber grommet, aluminum nut and sometimes a seat will also be present to properly seal the sensor to the rim. Within the valve stem, a brass or aluminum valve core will be installed to control the airflow. Regardless, they serve the same purpose - to keep the air in the tire. The valve may come in a rubber snap-in or an aluminum clamp-in package. The valve stem is what ultimately connects the sensor to the rim. This is why, in the case of a low battery or technical malfunction, the entire sensor body could require replacement. Because of the nature of these enclosures, the battery and other electronics cannot be accessed and, therefore, cannot be replaced. Either way, these two types of sensor enclosures house the electronic components, including the battery, inside of the sensor to keep them free from moisture, debris, and damage. It will either be laser welded with a cap or it might also have an epoxy-potted backing. The sensor body is the plastic enclosed object mounted inside of the tire that is attached to the valve stem. These important details prove to be very useful for service professionals when explaining TPMS service requirements to customers.Ī TPMS sensor should be thought of as having two different parts: the sensor body and the valve stem. In doing so, you will also discover why certain parts need to be serviced and why others require a complete replacement. One of the most important things you can do to ensure you are properly servicing TPMS is to fully understand all of the different parts of a TPMS sensor and what roles they play.
