The TPMS light on a Honda Pilot signals that one or more tires are under-inflated or that there is a fault in the Tire Pressure Monitoring System. It’s a safety alert you should address promptly to protect tire life and handling.
In practice, the light tells you to check tire pressures and, if needed, inflate to the recommended levels shown on the driver’s door placard or in the owner’s manual. If pressures are correct and the light stays on or blinks, the system may have a sensor or software fault that requires service.
Understanding the TPMS Light
The light is typically amber or yellow and appears as a tire with an exclamation mark, or the letters “TPMS.” It can indicate both underinflation and problems with the sensors or system that monitors tire pressure. Honda Pilot models use a Tire Pressure Monitoring System that largely relies on sensors in each wheel to trigger the warning when readings fall outside the programmed range.
When the light indicates low tire pressure
In most cases, a solid TPMS light means one or more tires are below the recommended pressure. Underinflated tires can reduce fuel efficiency, handling, tire wear, and overall safety.
Follow these steps to verify and correct tire pressure:
- Check the air pressure in all four tires (and include the spare only if your manual indicates it participates in TPMS) using a reliable tire gauge when the tires are cold.
- Inflate each tire to the recommended cold pressure printed on the driver's door jamb placard or in the owner's manual.
- Recheck pressures after inflation. Drive for about 10–15 minutes at a steady speed to allow the TPMS to relearn, if your vehicle supports automatic relearn. If your model requires a manual relearn, follow the procedure in the owner’s manual or the infotainment system.
Once the tires are at the correct pressures, the light should go out after a short drive. If it stays on, there may be a slow leak, a tire with a faulty valve stem, or a sensor issue that needs professional inspection.
When the light indicates a TPMS fault
Sometimes the light will come on or stay on due to a malfunction in the TPMS hardware or software, even if tire pressures are correct. A blinking TPMS light often signals a system fault requiring service.
What to do if you suspect a fault:
- Inspect tires for visible damage, punctures, or slow leaks and ensure sensors are properly mounted and seated after any tire work.
- Consider recent tire service—rotations, replacements, or sensor replacements—that might affect the monitoring system.
- Have a dealer or qualified shop run a TPMS diagnostic with the appropriate scan tool to read fault codes and reprogram or replace sensors as needed. In some cases, the sensor batteries may be exhausted and require replacement.
A TPMS fault means the system isn’t reliably warning you about underinflation until the issue is diagnosed and repaired. In the meantime, monitor tire pressures manually and maintain them at the recommended levels.
Practical tips and reminders
To keep the TPMS reliable and to avoid false alarms, follow these best practices:
- Check tire pressures monthly and before long trips, using a gauge, and always read the pressure when tires are cold.
- Rotate tires according to Honda’s schedule to promote even wear and sensor longevity.
- If you replace tires or sensors, have the TPMS properly programmed or relearned per the manual or dealership guidance.
Regular maintenance helps ensure the TPMS accurately reflects tire conditions and reduces the risk of driving with underinflated tires.
How the TPMS works in the Honda Pilot
The Honda Pilot’s TPMS relies on sensors installed in each wheel to monitor actual tire pressure and compare it to the recommended level. When air pressure falls below the threshold, the system triggers the warning light. If a sensor is faulty or if the system loses its calibration, the light may indicate a fault rather than a low-pressure condition. Always verify with a quick tire pressure check first, then proceed with professional diagnosis if the light remains on or blinks after inflating to spec.
Summary
The TPMS light on your Honda Pilot warns you to check tire pressures and inspect the TPMS system. If tires are inflated to the recommended cold pressures and the light goes out, you’re good to go. If the light stays on or blinks after inflation, there may be a tire leak or a sensor/system fault that requires service from a dealer or qualified technician. Regular tire maintenance and adherence to the door placard pressures help keep you safe and ensure the TPMS functions as intended.
How much does Honda charge to reset TPMS?
The average cost for a Honda Accord Tire Pressure Monitoring System Relearn is between $49 and $72. Labor costs are estimated between $49 and $72. This range does not include taxes and fees, and does not factor in your unique location. Related repairs may also be needed.
How do I fix the TPMS light on my Honda Pilot?
Resetting the TPMS Light on Honda Models with Touchscreen
- Turn the ignition to the “ON” position without starting the engine.
- Press the Home button on the touchscreen.
- Select Settings, then choose Vehicle.
- Tap TPMS Calibration or Tire Pressure.
- Select Calibrate and confirm.
Can I still drive if my TPMS sensor is bad?
In conclusion, driving a car with a bad TPMS sensor is not advisable due to the associated safety risks, reduced fuel efficiency, accelerated tyre wear and potential legal consequences.
Why is my TPMS light on but tires are fine on my Honda?
One of the most common reasons for a TPMS light staying on despite the tires being properly inflated is a sensor malfunction. TPMS sensors are typically located inside the tire and can wear out or become damaged over time, particularly if you've hit a curb, driven through a pothole, or been off-road.
