If you don\u2019t know much about this symbol, you might wonder, \u201cWhat\u2019s that light? What does it mean?\u201d If you know it well, the question may be \u201cDo I have a flat?\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Whatever your familiarity level, this warning light can be concerning for those who see it.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What does the TPMS light mean?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Two types of tire pressure monitoring systems (TPMS) can be found on vehicles today.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Some cars have direct TPMS systems where there are sensors on each wheel. Batteries and circuit boards can be found on these TPMS sensors.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There are also Indirect TPMS systems. Rather than using sensors, this setup goes based on the ride height.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The TPMS light clues you in on a few tire problems. It can mean that the tire pressure is low for one or multiple tires. This light can also indicate that something is wrong with a sensor.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What causes the TPMS light to come on?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Sensor problems: <\/strong>If your car features a direct TPMS system, the problem may lie with a sensor.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It\u2019s possible that it has a bad battery or circuit board.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/hometowneautorepairandtireofwoodbridge.com\/blog\/wp-content\/uploads\/2026\/02\/Bad-TPMS-sensor-on-Hyundai-Sonata-scaled.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"766\" height=\"1024\" src=\"https:\/\/hometowneautorepairandtireofwoodbridge.com\/blog\/wp-content\/uploads\/2026\/02\/Bad-TPMS-sensor-on-Hyundai-Sonata-766x1024.jpg\" alt=\"Bad TPMS sensor on Hyundai Sonata.\" class=\"wp-image-2829\" srcset=\"https:\/\/hometowneautorepairandtireofwoodbridge.com\/blog\/wp-content\/uploads\/2026\/02\/Bad-TPMS-sensor-on-Hyundai-Sonata-766x1024.jpg 766w, https:\/\/hometowneautorepairandtireofwoodbridge.com\/blog\/wp-content\/uploads\/2026\/02\/Bad-TPMS-sensor-on-Hyundai-Sonata-224x300.jpg 224w, https:\/\/hometowneautorepairandtireofwoodbridge.com\/blog\/wp-content\/uploads\/2026\/02\/Bad-TPMS-sensor-on-Hyundai-Sonata-768x1027.jpg 768w, https:\/\/hometowneautorepairandtireofwoodbridge.com\/blog\/wp-content\/uploads\/2026\/02\/Bad-TPMS-sensor-on-Hyundai-Sonata-1149x1536.jpg 1149w, https:\/\/hometowneautorepairandtireofwoodbridge.com\/blog\/wp-content\/uploads\/2026\/02\/Bad-TPMS-sensor-on-Hyundai-Sonata-1532x2048.jpg 1532w, https:\/\/hometowneautorepairandtireofwoodbridge.com\/blog\/wp-content\/uploads\/2026\/02\/Bad-TPMS-sensor-on-Hyundai-Sonata-100x134.jpg 100w, https:\/\/hometowneautorepairandtireofwoodbridge.com\/blog\/wp-content\/uploads\/2026\/02\/Bad-TPMS-sensor-on-Hyundai-Sonata-793x1060.jpg 793w, https:\/\/hometowneautorepairandtireofwoodbridge.com\/blog\/wp-content\/uploads\/2026\/02\/Bad-TPMS-sensor-on-Hyundai-Sonata-1080x1444.jpg 1080w, https:\/\/hometowneautorepairandtireofwoodbridge.com\/blog\/wp-content\/uploads\/2026\/02\/Bad-TPMS-sensor-on-Hyundai-Sonata-scaled.jpg 1915w\" sizes=\"auto, (max-width: 766px) 100vw, 766px\" \/><\/a><figcaption class=\"wp-element-caption\">Bad TPMS sensor on Hyundai Sonata<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Flat tire: <\/strong>A flat tire is another common reason why the TPMS light turns on.

The sidewalls might be wider at the ground level.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To confirm whether it\u2019s low, you can <a href=\"https:\/\/hometowneautorepairandtireofwoodbridge.com\/blog\/check-vehicles-tire-pressure\/\"><strong>check the tire pressure<\/strong><\/a> using a tire gauge.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you have a newer vehicle, it may come with a multi-information display that shows you the tire pressure.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/hometowneautorepairandtireofwoodbridge.com\/blog\/wp-content\/uploads\/2026\/02\/Tire-pressure-on-Toyota-RAV4-scaled.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"736\" src=\"https:\/\/hometowneautorepairandtireofwoodbridge.com\/blog\/wp-content\/uploads\/2026\/02\/Tire-pressure-on-Toyota-RAV4-1024x736.jpg\" alt=\"Tire pressure on Toyota RAV4.\" class=\"wp-image-2830\" srcset=\"https:\/\/hometowneautorepairandtireofwoodbridge.com\/blog\/wp-content\/uploads\/2026\/02\/Tire-pressure-on-Toyota-RAV4-1024x736.jpg 1024w, https:\/\/hometowneautorepairandtireofwoodbridge.com\/blog\/wp-content\/uploads\/2026\/02\/Tire-pressure-on-Toyota-RAV4-300x216.jpg 300w, https:\/\/hometowneautorepairandtireofwoodbridge.com\/blog\/wp-content\/uploads\/2026\/02\/Tire-pressure-on-Toyota-RAV4-768x552.jpg 768w, https:\/\/hometowneautorepairandtireofwoodbridge.com\/blog\/wp-content\/uploads\/2026\/02\/Tire-pressure-on-Toyota-RAV4-1536x1105.jpg 1536w, https:\/\/hometowneautorepairandtireofwoodbridge.com\/blog\/wp-content\/uploads\/2026\/02\/Tire-pressure-on-Toyota-RAV4-2048x1473.jpg 2048w, https:\/\/hometowneautorepairandtireofwoodbridge.com\/blog\/wp-content\/uploads\/2026\/02\/Tire-pressure-on-Toyota-RAV4-100x72.jpg 100w, https:\/\/hometowneautorepairandtireofwoodbridge.com\/blog\/wp-content\/uploads\/2026\/02\/Tire-pressure-on-Toyota-RAV4-793x570.jpg 793w, https:\/\/hometowneautorepairandtireofwoodbridge.com\/blog\/wp-content\/uploads\/2026\/02\/Tire-pressure-on-Toyota-RAV4-1080x777.jpg 1080w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption class=\"wp-element-caption\">Tire pressure on Toyota RAV4<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What should I do if my TPMS light appears?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Did your TPMS light make an unwelcome appearance?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The first step is ruling out the cause. Start by checking the tire pressure. You can also take it by an auto repair shop if you need help or want a little extra peace of mind.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A flat tire should be repaired or replaced.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For weather-related tire pressure problems, you will want to get your tires checked and refilled.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The appropriate tire pressure is found on the tire sidewall and driver\u2019s side door jam.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If there\u2019s plenty of air in your tires, a sensor could be failing. In this case, TPMS sensor replacement is needed.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">By making sure your tire pressure is where it needs to be, you help prevent your tires from wearing out too early.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">HomeTowne Auto Repair &amp; Tire is an authorized Michelin and BFGoodrich tire dealer located in Woodbridge, Virginia.
