TPMS Tech Tips How To Tell If A Vehicle Is Equipped With TPMS Here are three ways to identify vehicles equipped with a TPMS. TPMS symbol temporarily light ups on dashboard during start-up Tire pressure is displayed on dashboard during start-up Tires can be scanned by a specialized TPMS tool Tip: You cannot determine the presence of a TPMS simply by looking at the valve stem; TPMS systems now use both metal and rubber valves. Tip: The TPMS warning symbol lights when one or more tires becomes 25% under-inflated Tip: Before any tire service, rotation or replacement the TPMS sensors should be checked to make certain they are operational. Sensor operation can be verified in minutes by checking for a warning light or instrument read out or by using the TPMS diagnostic tool Tip: TPMS tools should be kept up-to-date and most can be updated using a PC or laptop via the internet. As new TPMS systems are introduced by vehicle manufacturers, these updates keep the tool from becoming obsolete or transmitting incorrect information Tip: Identifying the TPMS valve stem is easy with the cap removed. It has a bevel and the rubber coating does not go all the way to the threads like a typical rubber stem. Tip: Sensor damage or failure may occur from day one of vehicle ownership. Tip: Sensors are powered by non-serviceable batteries with a 3-10 year service life Tip: Rotating tires without resetting the TPMS system will set trouble codes, trigger the warning light and may lead to premature sensor battery failure Tip: Nickel plated electro-less valve cores must be used with TPMS valves. Regular copper or brass valve cores will cause galvanic corrosion of the valve stem and damage Tip: TPMS service parts should be replaced every time a tire is removed from the wheel — these may include Valve Stem, Cap, Valve Core, Nut, Washer & Seal Our message to motorists. This little sensor can save your life…plus monitoring tire pressure can help you save at the pump and improve overall performance…but only if the system is properly maintained. Tire rotations and repairs may now cost more as specialized tools are required to perform manufacturer specified TPMS relearn procedures. Your benefits are increased fuel efficiency, improved vehicle handling, lowered risk of hydroplaning, superior braking performance, shorter stopping distances, and extended tire life.  Safety.
