Honda TPMS Indicator
After a series of tire recalls in the early 1990’s the United States government legislated the “Tread Act” to adopt stricter safety requirements for the tire and auto manufacturers. One part of the tread act was the adopted use of tire pressure monitoring systems, or “tpms” for short. If your vehicle is a 2007 or newer model it has some form of a tpms system. The main benefit of these systems is to alert you in the event that your tire is lower than it should be. These systems are very sensitive and are designed to alert you before you lose a level of air that would be unsafe to operate or cause failures of your tires. While safety is the main benefit of tpms another benefit is fuel economy. Improperly inflated tires can have an extreme effect on your vehicles fuel economy.
Have you ever tried to ride a bike with a low tire? The same way a low tire on a bike is hard to get going, a low tire on your vehicle takes more power to operate resulting in poorer fuel economy. A properly operating tpms system constantly measures your tires and alerts you before it becomes unsafe, or you lose fuel economy. One other benefit is a longer tire life due to more consistent inflation pressures.
How does a TPMS system work?:
There are two main types of TPMS systems used in your Honda. A direct, and an indirect system. Direct systems use sensors mounted in each tire that wirelessly send the tire pressures to the computer in the vehicle. An indirect tpms system estimates the tire pressure through wheel speed sensors that measure the rotational speed of each tire. They detect when one tire rotates faster than the others to determine which tire is low.
Direct TPMS systems have batteries in each of the sensors which have a life of about 7-10 years. Once the battery is low the vehicle will set a TPMS light to alert you that it is low. Once one gets low it is a good idea to replace all four sensors so you don’t have to worry about the others failing at an inopportune time such as a road trip.
Weather: Tire pressure can fluctuate based on weather changes. If you have a change of 5-10 degrees in temperature it may cause the tire pressure to decrease to a level that is unsafe and cause your low tire light to come on. Once the tire pressure is changed to the correct level and the tpms system is re-calibrated the light will go off.
