The reset method depends on whether your Impala has a direct TPMS reset button or relies on driving to reset.
Method 1: Driving Reset (Most Likely)
This is the most common method for 2004 Impalas. The system often resets automatically after you've inflated your tires to the proper pressure and driven for a while (usually 10-20 minutes at speeds above 20 mph).
1. Inflate tires: Inflate all four tires to the recommended pressure (check the sticker on your driver's side doorjamb or your owner's manual).
2. Drive: Drive the vehicle for 10-20 minutes at speeds above 20 mph.
3. Check the light: After driving, check if the light has turned off. If it hasn't, try driving a little longer.
Method 2: Using a TPMS Tool (If Necessary)
If the driving method doesn't work, you might have a malfunctioning sensor. In this case, you'll likely need a TPMS tool. These tools can be purchased online or at auto parts stores. They allow you to relearn the sensor IDs to the car's computer. The exact procedure varies by tool, so consult the tool's instructions.
Important Note: If the light stays on after properly inflating your tires and driving, there might be a problem with one or more of your TPMS sensors. You should have a mechanic diagnose the issue to avoid potential safety hazards. A faulty sensor is more common than a system malfunction.
