GET TO KNOW YOUR TIRE PRESSURE MONITORING SYSTEM SAFETY DEVICE
The National Highway Traffic Safety Administration requires all vehicles made after 2007 to come equipped with a Tire Pressure Monitoring system warning system. The TPMS light on your dash is a safety device that wirelessly monitors tire pressure through a sensor in your tires or by using a wheel speed sensor as part of the ABS system to determine if wheels are rotating at different speeds while driving straight. If your TPMS light comes on, it’s telling you something don’t ignore it!
TPMS sensors are battery powered and last about 7-10 years and/or 100,000 miles. The battery inside the sensor isn’t replaceable, so when you have one sensor replaced due to battery failure, it’s recommended you replace all four sensors.
UNDERSTANDING YOUR CAR’S TPMS
If your car was manufactured in 2007 or later, it should have a Tire Pressure Monitoring System (TPMS). There are two types of systems: indirect and direct. Direct, the more common system today, uses sensors placed inside each wheel to provide precise real-time air pressure readings. An indirect system works with the Anti-lock Brake System to monitor if an underinflated tire causes one wheel to rotate faster than the others when driving straight down the road. Understanding your TPMS how and how it works is an important part of maintaining your vehicle and staying safe on the road.
