Have you ever noticed a small horseshoe-shaped warning light on your dashboard while driving? That is your TPMS light and it is trying to tell you something important. Understanding your tire pressure monitoring system can keep you safe on the road. Here is everything Sunnyside and Tri-Cities drivers need to know about their TPMS light.
What Is a TPMS Light?
TPMS stands for Tire Pressure Monitoring System. It is a safety system built into most modern vehicles sold in the United States after 2008. The tire pressure monitoring system uses sensors inside each wheel to monitor your tire pressure in real time. When pressure drops significantly below the recommended level, the TPMS light illuminates on your dashboard. It is your vehicle's way of alerting you to a potential tire pressure problem before it becomes a serious safety issue.
Why Is Tire Pressure So Important?
Underinflated tires affect your vehicle's handling, braking, and fuel economy significantly. They also generate excess heat during driving which can lead to premature tire wear or a dangerous flat tire. Overinflated tires reduce your vehicle's contact patch with the road surface. That reduces traction and makes your vehicle more susceptible to damage from road hazards and potholes.
Common Reasons Your TPMS Light Comes On
Temperature Changes
Tire pressure drops approximately 1 PSI for every 10 degree Fahrenheit drop in temperature. Eastern Washington's cold winter mornings can cause your TPMS light to come on temporarily. In many cases the light may go off once your tires warm up during driving.
Slow Leak or Puncture
A nail, screw, or road debris causing a slow leak is one of the most common causes of a TPMS light. A slow leak may not immediately cause a flat tire but will gradually reduce your tire pressure over time. Inspect your tires for visible damage as soon as possible.
Flat Tire
A sudden flat tire will immediately trigger your TPMS light. If your light comes on suddenly while driving, safely reduce your speed and pull over as soon as it is safe to do so. Do not continue driving on a flat tire as it can cause serious damage to your wheel.
Faulty TPMS Sensor
Each wheel has its own individual tire pressure monitoring system sensor. A sensor can fail due to age, battery depletion, or physical damage during a tire change. Our service team at Speck CDJR can quickly diagnose and replace a faulty TPMS sensor.
What Should You Do When Your TPMS Light Comes On?
Step 1: Stay Calm and Check Your Tires
Pull over safely and visually inspect all four tires for obvious signs of damage or deflation. Use a tire pressure gauge to check the pressure in each tire. Compare the reading to the recommended PSI on the sticker inside your driver's door jamb.
Step 2: Add Air If Needed
If one or more tires are low, add air at the nearest gas station or service center. Add air until the pressure matches the recommended PSI on your door jamb sticker.
Step 3: Visit Speck CDJR If the Light Stays On
If your TPMS light stays on after adding air, bring your vehicle to Speck CDJR in Sunnyside. Our certified technicians will diagnose the issue quickly and accurately. We will let you know whether you need a tire inflation, a flat tire repair, or a TPMS sensor replacement.
When Is It Safe to Keep Driving?
If your TPMS light comes on and your tires appear visually normal, it is generally safe to drive to the nearest service center. However, do not drive at highway speeds on a significantly underinflated tire. A slow leak can quickly become a dangerous flat tire at highway speeds. Address any TPMS warning as soon as possible.
