Inflate your tires to the manufacturer’s recommended cold pressures and allow the system to relearn; if the warning persists, use the TPMS reset procedure (if your trim supports it) or have the system checked for leaks or faulty sensors.
Check and adjust tire pressures
Ensuring all four tires are at the correct cold pressure is the essential first step. Underinflation triggers the tire pressure monitor, can affect handling, and wastes fuel. Use a reliable gauge and verify pressures before driving.
Follow these steps to verify and adjust tire pressures to the recommended level:
- Find the recommended cold tire pressure on the door jamb placard or in the owner’s manual for your specific Civic trim and tire size.
- Check each tire’s pressure when the tires are cold (the car hasn’t been driven more than a few minutes).
- Inflate or deflate each tire to the recommended pressure, and recheck with a gauge to confirm accuracy.
- If any tire has visible damage, puncture, or a slow leak, address that issue before driving again.
After correcting pressures, drive the car for several miles at highway speeds if possible to allow the TPMS to relearn the new pressures. If the light remains on, proceed to the reset steps below.
Resetting the TPMS (tire pressure monitoring system)
Some 2015 Civics include a TPMS reset option; others rely on a highway relearn. Use the method that matches your vehicle’s features.
- If your Civic has a TPMS reset button, locate it (often near the glove box or under the left side of the dash). With the ignition on (engine off), press and hold the TPMS button until the indicator light on the dash flashes or blinks, then release. After this, drive at speeds above about 50 mph for 10 minutes or so to complete the relearn.
- If there is no reset button, simply driving at highway speeds for 10–20 minutes typically triggers a relearn. You may need to repeat this over a couple of trips if the light doesn’t go out right away.
- If the light stays on after attempting reset and highway relearn, inspect all four tires again for leaks, or consider that a sensor or receiver may be failing. A tire shop or Honda service adviser can run a TPMS diagnostic and replace faulty sensors if needed.
After attempting reset and relearn, the TPMS light should extinguish once the system recognizes the correct pressures. If it remains illuminated, professional diagnostics are recommended to check sensor health and system wiring.
When to seek professional help
Warning lights can indicate more than a simple reset. If the light persists after inflation and relearn attempts, or if you notice tire damage, the cylinder-like replacement of TPMS sensors, or a whistling/leaking tire, it’s time to consult a professional.
- The TPMS light stays on despite inflated tires and a successful relearn attempt.
- You suspect a puncture, slow leak, or damaged tire that needs repair.
- You suspect a faulty TPMS sensor or module that requires diagnostic equipment.
Professional evaluation at a tire shop or Honda dealership can diagnose sensor faults, replace faulty parts, and reset the system to restore accurate monitoring.
Summary
For a 2015 Honda Civic, the tire pressure warning typically resolves after inflating all four tires to the recommended cold pressure and enabling the system to relearn. If the warning persists, use the vehicle’s TPMS reset procedure (if equipped) or drive at highway speeds to trigger a relearn. Persistent issues should be evaluated by a qualified technician to check for leaks or sensor faults. Regularly checking tire pressures and maintaining proper inflation helps prevent TPMS warnings in the future.
