Reasons for the XRv tire pressure yellow light coming on for no reason: Abnormal tire pressure: Generally, an alarm will be triggered if the pressure is below 1.8bar or above 3.0bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the tire pressure monitoring system will still record the previous data, causing the tire pressure monitoring indicator light to come on. In this case, simply perform a tire pressure reset. Damaged tire pressure sensor: The tire pressure sensor is used to monitor tire pressure and is directly installed inside the tire, connected to the tire inflation port. If the tire pressure sensor is damaged due to impact while driving, it can also cause the tire pressure warning light to come on. For sensor damage issues, the only solution is to replace it with a new component. Method for resetting tire pressure monitoring: First, turn on the ignition switch, press and hold the tire pressure monitoring reset button until you hear a "beep" sound, then release it. The tire pressure monitoring system will store the current normal tire pressure data, automatically clear the previous data, and finally, the warning light on the dashboard will turn off, completing the tire pressure reset.
Recently, my XR-V also experienced the situation where the tire pressure warning light came on for no apparent reason. I was in a panic, thinking it might be a flat tire, so I quickly pulled over to check. All four tires were fine, with pressures around 2.5 Bar. Later, I consulted a mechanic friend who said the most common reasons are extreme cold or hot weather causing the tires to expand or contract, leading to false alarms from the tire pressure monitoring system, or mud and dirt on the sensor probes affecting the signal. It could also be that the sensor's battery is dead, as those small batteries eventually run out. I tried resetting the system myself: start the car, find the settings menu on the central display, click the tire pressure reset button, and wait a few seconds for the light to go off. If that doesn’t work, you’ll need to visit a professional shop to check if the sensor is faulty. I recommend checking the tire pressure every time before driving, especially during seasonal changes, to avoid sudden warning lights. Regular maintenance can save a lot of hassle.
