1. Inflate your tires: Check the pressure in all four tires (including the spare if applicable) using a reliable tire gauge. Inflate them to the correct pressure listed on the sticker usually found on the driver's side doorjamb or in the owner's manual. This is the most common reason for the light.
2. Wait: After inflating the tires to the correct pressure, drive the car for a short distance (around 10-15 miles). The system often needs some driving time to reset. The light should turn off automatically once the system recognizes the correct pressure.
3. Check for leaks: If the light stays on after inflating and driving, you likely have a slow leak in one or more tires. Have them checked by a tire professional to locate and repair the leak.
4. TPMS Sensor Issues (if applicable): Your 2001 Impala may or may not have a TPMS. If it does and the above steps don't work, one or more of your TPMS sensors may be faulty. These sensors can fail and need to be replaced. A tire professional or mechanic can diagnose this. Some auto parts stores can test sensors.
5. OBD-II Scanner (Not Recommended): While some OBD-II scanners *might* allow you to clear the code, this is not recommended. Clearing the code without fixing the underlying problem (low tire pressure or a faulty sensor) is unsafe and will only temporarily turn off the light. The light is there for your safety.
In short: Inflate your tires properly. If the light remains on, there's a problem that needs professional attention. Don't just try to erase the light; fix the problem causing it.
