How to reset TPMS 2014 Chevy Impala?
Understanding the TPMS and why resets are needed
Manual TPMS Relearn: Button-based procedure
- Inflate all tires to the recommended cold pressures shown on the driver-side door placard.
- Turn the ignition to ON with the engine OFF (accessory position) and ensure the vehicle is stationary.
- Press and hold the TPMS reset/learn button until the TPMS indicator light (or a message in the instrument cluster) blinks slowly — typically about 5 seconds — then release.
- Wait for the system to acknowledge the relearn. The light may flash or turn off after successful relearn.
- Drive the vehicle at a steady speed (around 50 mph / 80 km/h or higher) for 10 minutes to finalize the learning process.
Note: If you cannot find a reset button, skip to the Drive-to-Learn procedure described later in this article.
After this procedure, the TPMS light should behave normally. If the light continues to blink or stays on, repeat the steps once more, or proceed to the Drive-to-Learn method described below. If you’ve recently replaced sensors or wheels, you may need a dealership tool to complete the relearn.
Drive-to-Learn procedure (no reset button)
- With the ignition ON (engine OFF) or as specified for your model, drive the car straight and steadily on a clear highway.
- Maintain a steady speed around 50 mph (80 km/h) or higher for about 10–15 minutes, avoiding hard braking and sharp turns.
- After driving for the allotted time, stop and check the instrument cluster for the TPMS light status. If it remains on, you may need to repeat the drive cycle or consult a shop for a reset.
Before you begin, ensure all tires are inflated to the recommended cold pressures noted on the placard.
Drive-to-Learn is typically effective for sensors that are functioning correctly and tires that are at the proper pressures. If the light persists after multiple attempts, there may be a faulty sensor or other tire/wheel issue requiring professional service.
Troubleshooting: Light stays on or sensor issues
- Recheck all tire pressures with a high-quality gauge to confirm they match the door placard values.
- Inspect tires for punctures, slow leaks, or damaged valve stems that could cause persistent low pressure readings.
- Inspect wheel sensors and wiring for damage or corrosion, especially after a tire change or wheel swap.
- If sensors were replaced, confirm the vehicle has a proper TPMS relearn with the correct tool; some replacements require programming or initialization with a scan tool.
- Visit a Chevrolet service center or tire shop if the light continues to behave abnormally.
Persistent TPMS warnings can indicate sensor failure, a damaged wheel, or a tire with a slow leak. Addressing these issues promptly helps maintain tire safety and fuel efficiency.
What you should know about tire pressures
Always use the cold-tyre pressures listed on the driver’s door placard for your specific Impala model. If you’ve just driven, wait for the tires to cool before taking a measurement, as temperatures affect the readings. Seasonal changes and load conditions can also influence ideal pressures.
