1. Check your tire pressure: This is the most common cause. Use a reliable tire pressure gauge and check the pressure in each tire, including the spare. Compare the readings to the recommended pressure listed in your vehicle's owner's manual (usually found on a sticker inside the driver's side doorjamb or fuel door). Inflate tires to the correct pressure.
2. Check for leaks: After inflating, monitor your tires for a few days to see if any are losing air. Look for slow leaks, punctures, or damaged valves. If you find a leak, you'll need to repair or replace the tire.
3. Check the TPMS sensors: Sometimes the sensors themselves malfunction. This requires professional diagnosis and potentially sensor replacement or reprogramming. A tire shop or mechanic can check this.
4. Reset the TPMS (if necessary): Once you've addressed the pressure issue and/or repaired a leak, you may need to reset the TPMS system. The method for doing this varies by vehicle. Consult your owner's manual for instructions. Often, it involves driving for a short period at a moderate speed.
5. Consider a faulty sensor: If you've checked everything above and the light remains on, one or more of your TPMS sensors might be faulty. A professional mechanic will have the tools to diagnose this problem.
In short: Don't just try to ignore or "get rid" of the warning light. It's there to alert you to a potential safety hazard. Properly inflate your tires, check for leaks, and if the problem persists, seek professional help.
