tire pressure monitoring system
Posted on by

The Tire Pressure Monitoring System (TPMS) is a crucial safety feature in most of today’s vehicles. It alerts drivers when tire pressure is too low, which can help prevent accidents and improve fuel efficiency. However, there are times when the TPMS warning light illuminates, but the tire pressure seems perfectly fine.  In this month’s blog post, we take a closer look at what might be happening.

  1. Faulty TPMS Sensors:  One of the most common reasons for a TPMS warning with normal tire pressure is a faulty sensor. Over time, sensors can wear out or malfunction, leading to inaccurate readings. If your tire pressure is correct, have the TPMS sensors checked and replaced if necessary.
  2. Battery Issues:  TPMS sensors are powered by small batteries that can eventually die. When a sensor’s battery is low or dead, it can trigger the warning light even if tire pressure is adequate. Replacing the battery or the sensor itself can resolve this issue.
  3. Sensor Recalibration Needed:  Sometimes, TPMS sensors need to be recalibrated. This can happen after tire rotations, replacements, or changes in tire pressure. Refer to your vehicle’s owner’s manual for instructions on how to recalibrate the TPMS or have a professional handle it.
  4. Interference from Electronic Devices:  Occasionally, electronic interference from other devices can cause the TPMS to malfunction. If you have recently added new electronic equipment to your vehicle, consider removing it to see if the warning light goes off.
  5. Extreme Temperature Changes:  Drastic temperature fluctuations can affect tire pressure readings. If the TPMS warning light turns on during extreme weather, double-check the tire pressure and monitor it as temperatures stabilize.

What to Do When the TPMS Light Comes On

If the TPMS warning light illuminates and you have verified that your tire pressure is fine, it’s best to have the system inspected by a professional. They can diagnose and fix any underlying issues to ensure your TPMS is functioning correctly.  If you have any current issues with your TPMS, contact the service professionals at Car Kings to schedule an inspection and/or repairs.
