How Do New Cars Sense Tire Pressure?

The tires are the only part of your vehicle that contacts the road. Maintaining the right air pressure is crucial to a smooth ride and even wear regardless of the tire manufacturer. Fuel economy can also be affected by low tire pressure. Government regulations mandate that vehicles built after 2007 have tire pressure sensors to assist the driver in keeping pressure correct before any damage or uneven wear occurs. This can save you from replacing a tire which has been run with low air for an extended time.

A warning light on the dashboard in the shape of a horseshoe with an exclamation point in the center is the low tire pressure indicator. The Tire Pressure Monitoring System or TPMS alerts the driver when a tire is 25 percent or more under inflated by activating the warning light. There is a system available on several vehicles that can display all four tires in the warning system to signal exactly which tire has a low air condition.

There are two TPMS options available. Direct monitoring is the most accurate and uses a sensor inside of each tire. The sensor is usually attached to a special tire valve. This method gives the driver a low pressure warning signal instantly when necessary. The second option is an indirect system that uses information gathered from the vehicle’s ABS system. A problem with this option is the inability of the system to detect a low air condition on all four tires at once. This condition can occur during rapid temperature changes.
