Addressing a Faulty TPMS Sensor in a 2021 Chevrolet Silverado 1500 T1XX

Tools Required
  • OBD-II Scanner
  • Tire Pressure Gauge
  • TPMS Tool (if available)
  • Socket Set and Wrench
  • Tire Iron
  • Torque Wrench
  • Jack and Jack Stands (if necessary)
  • Replacement TPMS Sensor (if needed)
  • Valve Stem Tool (if needed)
Repair Instructions
Step 1: Check and Inflate Tires
  1. Check All Tire Pressures: Ensure all tires are inflated to the recommended pressure found on the driver’s side door jamb.
  2. Adjust as Necessary: Inflate or deflate tires as needed and recheck with the gauge.
Step 2: Scan for DTCs
  1. Connect the OBD-II Scanner: Plug the OBD-II scanner into the diagnostic port under the dashboard.
  2. Power On the Scanner: Follow the prompts to navigate to the TPMS section and retrieve any fault codes.
  3. Document Any Codes Found: Take note of any codes for further investigation.
Step 3: Visual Inspection
  1. Remove Any Wheel Covers: If applicable, remove covers to access the TPMS sensors.
  2. Inspect Each Sensor: Look for physical damage, corrosion, or loose connections at each valve stem.
  3. Check for Leaks: Spray soapy water around the valve stems to check for air leaks.
Step 4: Testing the Sensors
  1. Activate Each Sensor: Use the TPMS tool to activate each sensor and read the data.
  2. Confirm Functionality: Ensure that each sensor responds correctly with the appropriate tire pressure readings.
Step 5: Replace Faulty TPMS Sensor
  1. Loosen the Wheel Lug Nuts: Use a tire iron to slightly loosen the lug nuts of the wheel with the faulty sensor while the vehicle is on the ground.
  2. Jack Up the Vehicle: Safely lift the vehicle using a jack and secure it with jack stands.
  3. Remove the Wheel: Completely remove the lug nuts and take off the wheel.
  4. Remove the Old Sensor:
    • Use a socket to remove the valve stem nut and pull the sensor out of the tire.
    • If necessary, deflate the tire to fully access the sensor.
  5. Install the New Sensor:
    • Insert the new TPMS sensor into the valve stem and secure it with the nut.
    • Ensure it is tightened to manufacturer specifications (usually around 3-5 Nm).
  6. Reinstall the Wheel: Place the wheel back on and hand-tighten the lug nuts.
  7. Lower the Vehicle: Carefully lower the vehicle and remove the jack stands.
  8. Torque the Lug Nuts: Use a torque wrench to tighten the lug nuts to the manufacturer’s specifications (typically 140-175 lb-ft).
Step 6: Relearn TPMS Sensors
  1. Start the Vehicle: Turn on the ignition but do not start.
  2. Use the TPMS Tool for Relearning: Follow the TPMS relearn procedure specific to the Chevrolet Silverado, which may involve driving the vehicle for a short distance or using the tool to complete the process.
  3. Check for Warning Light: After the relearn procedure, check if the TPMS light has turned off.
Step 7: Final Check
  1. Confirm All Sensors are Working: Use the TPMS tool to verify that all sensors are operational.
  2. Double-Check Tire Pressures: Ensure all tires are back to their recommended pressures.

By following these steps, you should be able to diagnose and address any issues with the TPMS sensor in your 2021 Chevrolet Silverado 1500 T1XX. If problems persist, consider consulting a professional technician for further assistance.
