Does the Tire Pressure Monitoring System Need to Be Reset After Tire Repair?
2 Answers
Tire pressure monitoring system must be reset after tire rotation, also known as "tire pressure learning." Each tire is equipped with a tire pressure sensor that transmits tire pressure data to the vehicle's tire pressure control system via wireless communication. Principle: The tire pressure monitoring system essentially sets a specific pressure value for the tires. If the tire pressure falls below this set value, an alarm is triggered. After repairing the tire, each tire should be tested again. Once the tire pressure is properly adjusted, press the tire pressure monitoring button for 3 seconds to allow the computer to record the current tire pressure. Reset: Every time a tire is replaced, such as with a spare tire, or when the tire pressure changes after reinstallation, the system should be reset.
Just had my tire patched last week and ran into this issue, so I specifically asked my mechanic friend. He said that in most cases, the tire pressure monitoring system (TPMS) will automatically reset after a tire repair, but sometimes you have to manually reset it, especially if the wheel was removed. This is because the sensor position might have shifted, and the system still thinks the tire is leaking. Resetting is simple—there’s a dedicated reset button in the car, usually located under the steering wheel or inside the glove compartment, and the manual definitely states its location. If you don’t reset it, that little yellow warning light on the dashboard keeps staying on, which can be unnerving. It’s best to check before hitting the highway to avoid false alarms causing delays. There’s also a specific pressure to inflate the tire after patching—standards vary by car model, so remember to check the label on the door frame.
