What does 'Please check the tire pressure monitoring system' mean?

Please check the tire pressure monitoring system: This alert indicates abnormal air pressure in one of the tires, requiring inspection of the tire condition. The tire pressure monitoring system can be categorized into the following two types: 1. Indirect tire pressure monitoring system: Determines tire abnormalities through differences in wheel rotation speed. Working principle: When a tire's pressure decreases, its rolling radius reduces, causing it to rotate faster than other wheels. The system monitors tire pressure by detecting these rotational speed differences. 2. Direct tire pressure monitoring system: Equips each tire with a pressure sensor to monitor tire pressure and temperature in real-time, whether the vehicle is stationary or in motion. It provides timely alerts for high pressure, low pressure, or high temperature conditions, helping prevent traffic accidents caused by tire failures and ensuring driving safety.
As an average car owner with several years of driving experience, I remember being completely baffled when I first saw the 'Check Tire Pressure Monitoring System' warning on my dashboard. Essentially, it means there's an issue with your vehicle's TPMS—perhaps a tire sensor isn't transmitting signals or there's a system glitch. While not an immediate emergency, it demands attention because the TPMS serves as a safety net to alert you about underinflated or flat tires. I ignored it once, only to discover a slow leak days later—had I not caught it in time, driving on the highway could've been risky! My advice: pull over safely when the warning appears, use your onboard tire pressure gauge or visit a gas station to check each tire's pressure against the manual's specifications. If pressures are normal but the light persists, it's likely a dead sensor battery or other fault requiring a mechanic's inspection. Pro tip: include TPMS checks during routine maintenance to prevent issues and extend tire life, saving you fuel costs in the long run.
I've been driving for over 20 years and often help friends with minor car issues. 'Check Tire Pressure Monitoring System' indicates a potential malfunction in the tire pressure monitoring function, not necessarily a leak in the tires themselves. Common causes include depleted sensor batteries (typically lasting around 5 years), signal interference, or aging system wiring. The solution is straightforward: first visually inspect the tires for any visible deflation, then use a tire pressure gauge to check if the pressure meets standard values (most vehicles require 30-35 psi). If everything appears normal but the warning light remains on, avoid embarking on long trips immediately as this could mask actual tire pressure issues. I recommend visiting a professional shop promptly to diagnose the TPMS sensors using specialized tools. After replacing and matching new components, the warning light should turn off. Safety comes first - delaying repairs increases the risk of tire blowouts, uneven tire wear, compromised handling, and reduced fuel efficiency.
From a technical perspective, the tire pressure monitoring system is TPMS, which uses sensors to monitor tire pressure. The warning indicates a system self-check failure, possibly due to sensor malfunction, control unit error, or signal loss. Causes include component aging from prolonged use, damage from bumpy road conditions, or depleted batteries. This doesn't affect immediate driving but requires prompt attention. After confirming normal tire pressure with a gauge, you can drive temporarily but should schedule repairs. Sensor replacement typically costs a few hundred yuan, and the warning light will turn off automatically after programming. Remember, ignoring it means you won't receive alerts if tire pressure is actually low, increasing the risk of losing control at high speeds—a major safety concern.
