If your TPMS warning light is on, you’ll typically need to inflate all tires to the recommended pressures and perform a TPMS relearn. Depending on your trim, you may have a dedicated learn button or you may rely on a drive-to-relearn method.
Understanding TPMS on the 2012 Honda Accord
The Tire Pressure Monitoring System (TPMS) helps alert you when a tire is underinflated. After adjusting tire pressures or rotating tires, the system may need to relearn the new sensor positions. Reset steps can vary slightly by model and trim, but the core idea is to ensure each wheel’s sensor is recognized by the system and that all tires are at the correct pressure.
Methods to Reset or Relearn TPMS
Use one of the following approaches depending on your car’s equipment. The first method is for vehicles with a dedicated TPMS learn button. The second method covers the standard drive-to-relearn process used when no button is available or when the button procedure doesn’t respond.
With a TPMS Learn Button
- Turn the ignition to ON and ensure the engine is off, then locate the TPMS learn button. Common locations include the lower left side of the dash near the steering column or behind the glove box.
- Press and hold the button until the TPMS indicator in the instrument cluster blinks or confirms learning (exact pattern can vary by model).
- Drive at speeds above 30 mph (50 km/h) for about 10 minutes to complete the relearn.
After completing these steps, check the TPMS light. It should go out once the sensors have been relearned. If the light remains on, retry the procedure or check tire pressures and inspect sensors for damage or leaks.
Drive-to-Relearn (No Button or Button Not Responding)
If your Accord does not have a functional TPMS learn button or you prefer the standard method, follow these steps:
- Inflate all four tires to the recommended cold tire pressures listed on the door jamb sticker or in the owner's manual.
- With the ignition on and the engine running (as advised in your manual), drive straight on a clear road at steady speeds above 30 mph (50 km/h) for 10–20 minutes.
- Check the instrument cluster; the TPMS light should turn off once the sensors are relearned. If it stays on, you may need to repeat the drive or have sensors checked for faults.
If the light remains illuminated after attempting a relearn, there could be a faulty sensor, a dead battery in a sensor, or another underlying issue requiring a professional diagnosis with a scan tool.
Before You Reset: Check Tire Pressures
Always verify that all tires are inflated to the OEM-recommended pressures before attempting a TPMS relearn. Under- or over-inflation can cause improper readings and may trigger the warning light even after a relearn. The door jamb placard or your owner's manual lists the correct pressures for the front and rear tires.
Troubleshooting Tips
If you’ve completed the relearn steps and the TPMS light remains on, consider these checks:
- Inspect tires for leaks or punctures that could cause gradual pressure loss.
- Check the TPMS sensors themselves for damage or battery failure; sensors are typically located inside each wheel.
- If you’ve recently replaced tires or wheels, confirm that the new sensors are compatible and properly programmed for the vehicle.
- Consult a service professional with a TPMS-enabled scan tool if the light persists.
Summary
Resetting the TPMS on a 2012 Honda Accord generally involves inflating all tires to the recommended pressures and either using a dedicated TPMS learn button (if equipped) or performing a drive-to-relearn by driving at highway speeds. If the warning light does not extinguish after attempting these methods, there may be a faulty sensor or another issue requiring professional diagnostic and service.
