However, if the automatic relearn process doesn't work, you might need to perform a manual relearn procedure. This procedure varies slightly depending on whether your Silverado has direct TPMS sensors (in the valve stems) or indirect TPMS (relies on wheel speed sensors). Since your truck is a 2007, it's almost certainly a direct TPMS system.
Here's how to attempt a manual relearn for a direct TPMS system:
1. Inflate your tires to the correct pressure. Check the sticker on your driver's side doorjamb for the recommended tire pressure.
2. Turn the ignition to the "ON" position. Do *not* start the engine.
3. Locate the TPMS relearn procedure in your owner's manual. This is the most crucial step. The exact procedure is specific to your Silverado's model year and trim level. Your owner's manual will have the detailed instructions, which may involve using the gas pedal, brake pedal, or other specific key sequences. There's no universal method.
4. Follow the instructions precisely. The manual will tell you how long to hold the key in a certain position or how many times to press the gas or brake pedal to initiate the relearn sequence.
5. Drive the vehicle for 10-20 minutes at speeds above 20 mph. This allows the system to learn the new pressure readings from the sensors.
If you cannot find the relearn procedure in your owner's manual, or if the manual relearn doesn't work:
* Check the tire pressure again. Ensure all tires are at the correct pressure.
* Consider a faulty sensor. A malfunctioning TPMS sensor will require professional diagnosis and replacement. A mechanic can use a scan tool to identify which sensor (if any) is causing the problem.
* Consult a Chevrolet dealer or a qualified mechanic. They have the tools and expertise to properly diagnose and resolve TPMS issues.
Important Note: Trying to reset the system without following the proper procedure outlined in your owner's manual might not work and could potentially damage the system. Always refer to your owner's manual for the correct instructions.
