Why is My Tire Pressure Light Still On After Filling Tires
You’ve diligently filled your tires with air, but that stubborn tire pressure light persists. Don’t worry; at Urban Lube, a Professional Tire Replacement shop in Calgary, Alberta, we understand the importance of safe driving conditions and we’re here to guide you through troubleshooting your persistent tire pressure light.
What is a Tire Pressure Monitoring System (TPMS)?
TPMS stands for Tire Pressure Monitoring System. It’s a crucial safety feature in vehicles that monitors tire pressure in real-time. When it detects significantly low pressure in any tire, it promptly alerts the driver through a dashboard warning light. TPMS ensures optimal tire pressure, enhancing safety, fuel efficiency, and tire longevity.
Why is the TPMS Light Still Blinking?
Check Tire Pressure: Start with the basics. Ensure tires are inflated to the manufacturer’s recommended pressure levels. Consult your vehicle manual or the placard inside the driver’s side door frame for correct PSI values.
Valve Stem Issues: Faulty or damaged valve stems can cause air leakage, keeping the tire pressure light on. Inspect valve stems for wear, cracks, or leaks, and replace them if necessary.
Tire Damage: Even minor punctures or damage can lead to slow leaks, triggering the tire pressure light. Check tires for debris in the tread and inspect sidewalls for cuts or bulges.
Faulty Tire Pressure Sensors: Modern vehicles use TPMS sensors that can malfunction over time, leading to inaccurate readings. Professional diagnostics may be needed to identify and fix sensor issues.
Temperature Fluctuations: Calgary’s climate can cause tire pressure changes. Monitor pressure regularly, especially during temperature fluctuations, and adjust as needed.
Residual Air Loss: Sometimes, air loss occurs after filling tires due to improper sealing or valve issues. Recheck pressure after a few hours to ensure it remains at the recommended level.
