Inflate all tires to the manufacturer’s recommended pressures and drive at highway speeds for a short relearn period; if your car has a TPMS reset button, use it according to the manual to initiate the relearn. This guide covers both automatic relearn and manual reset options for the 2012 Accord.
This article explains how the Tire Pressure Monitoring System (TPMS) on a 2012 Honda Accord can be reset or relearned. It covers when you should perform a reset, the two primary methods (automatic relearn by driving and manual reset if equipped), what to check before resetting, and steps to take if the warning light persists. Proper tire pressure is essential for safety and accurate TPMS readings.
Before you reset: check tires and setup
Resetting TPMS works best when each tire is at its correct cold inflation pressure and the wheels and sensors are in good condition. Start by confirming the tire pressures on all four tires match the door jamb placard. If you’ve just rotated or replaced tires, plan for a relearn. Once pressures are correct, choose the relearn method you will use.
Automatic relearn by driving (no button required)
Most 2012 Hondas will relearn automatically after the tires are inflated to the proper pressure. You simply drive the vehicle for a period with stable speeds, and the system recognizes the new sensor IDs.
- Inflate all tires to the recommended cold pressures listed on the door placard for your Accord’s trim and tire size.
- Drive at a steady speed above about 50 mph (80 km/h) for at least 10 minutes to allow the system to relearn the sensor IDs.
If done correctly, the TPMS warning light should either turn off after the relearn or remain off once you finish the drive. If it stays on, proceed to the manual method or consult a shop.
Manual reset using the TPMS button (if equipped)
Some 2012 Accord models include a TPMS reset button. The exact location can vary, but it is often found under the dashboard near the left-foot area or in the glove box. If your car has this button, use the following steps to initiate a relearn.
- Turn the ignition to ON with the engine off (key in the ON position). Ensure all tires are at the correct cold pressures.
- Locate and press/hold the TPMS reset button until the TPMS indicator light blinks or the dashboard message confirms reset (often two blinks or a change in the light’s pattern).
- Release the button and drive for at least 10 minutes at highway speeds to complete the relearn process.
Note: If you cannot find a reset button or the procedure doesn’t work, it may not be present on your trim, or the system may require a professional relearn with specialized equipment.
What to do if the TPMS light stays on after reset
If the TPMS warning light remains illuminated after attempting a relearn, there may be a tire leak, a faulty sensor, or a battery issue in one of the sensors. Take these steps to troubleshoot:
- Check all tire pressures again when cold and inflate to the recommended values.
- Look for visibly underinflated tires and signs of slow leaks (punctures, nails, or valve stem issues).
- Inspect tire valves and caps; missing or damaged valves can trigger TPMS warnings.
- If pressures are correct and the light stays on, have a tire shop or Honda technician inspect the TPMS sensors and the receiver ECU. A sensor replacement or reprogramming may be required.
Persistent TPMS warnings after basic checks typically require professional diagnosis, especially if a sensor battery has failed or a sensor ID needs reprogramming.
Summary
Resetting TPMS on a 2012 Honda Accord can usually be done automatically by driving with properly inflated tires, or manually if the vehicle is equipped with a TPMS reset button. Start by confirming correct tire pressures, then choose the relearn method. If the warning light persists after following these steps, there may be a faulty sensor or leak that requires professional inspection.
