Why is my TPMS light on but tires are fine on my Honda?
Usually, the TPMS light comes on because the system detects low inflation, a failing sensor, or a required relearn after service or temperature changes—even if the tires look okay. Start by verifying the actual tire pressures with a gauge, then address any sensor or relearn needs if pressures are within the recommended range.
What the TPMS light signifies
The Tire Pressure Monitoring System (TPMS) is designed to alert you when one or more tires are underinflated or when there is a fault in the system itself. A warning can mean a real pressure issue, a sensor problem, or the need to relearn the system after maintenance or tire changes. In some cases, ambient temperature shifts can trigger a temporary warning even when tires appear fine.
Common causes when the tires look fine
Below are the typical reasons your TPMS light might stay on despite tires that appear normal. Each cause can be diagnosed with a quick check or a service scan.
- Underinflation in one or more tires (cold or warm conditions can affect pressure).
- Faulty or dead TPMS sensor battery in one of the wheels.
- TPMS sensor needs relearn or reprogramming after tire rotation, replacement, or battery disconnect.
- Leaking valve stems or damaged/contaminated sensors.
- Temperature changes causing temporary pressure reductions.
- Faulty TPMS control module or sensor codes that require a diagnostic scan.
Note: In many Honda models, a TPMS fault will require either a relearn procedure or a sensor replacement, and certain service events (like tire work) can trigger the need to reprogram the system.
How to diagnose and fix
Use this practical checklist to determine whether the light means a real pressure issue or something in the TPMS itself.
- Check all four tires (and the spare if your car has one connected to the TPMS) with a reliable gauge. Inflate to the vehicle’s recommended cold inflation pressure, usually found on the door jamb sticker.
- Inspect tires for slow leaks, punctures, or damaged valves. Use soapy water on valve stems and around the tire bead to spot leaks.
- If all pressures are correct, scan the TPMS with an OBD-II tool or take the car to a tire shop or Honda dealer to read fault codes and confirm sensor status.
- If a sensor is faulty or its battery is dead, replace the sensor(s). Note that TPMS sensor replacement typically requires professional installation and programming.
- Perform a TPMS relearn (also called a relearn procedure) if the vehicle requires it after sensor replacement or certain tire service. Procedures vary by model; you may need to drive at a certain speed for a set time, or use a menu/button sequence in the car’s settings to initiate relearn. Consult your owner’s manual or a Honda dealer for the exact steps for your year/model.
- Recheck after the relearn: the light should reset once the system successfully recognizes the correct sensor data from each wheel. If it remains on, a diagnostic scan is warranted to identify any persistent fault.
Regular maintenance—like ensuring tires are inflated to spec after temperature shifts and keeping an eye on sensor condition during tire service—can prevent unnecessary TPMS warnings from becoming a recurring issue.
Honda-specific notes
Honda TPMS procedures can vary by model and year. In many recent Hondas, a relearn or drive-to-learn process is common after tires are serviced or sensors are replaced. If you’re unsure, the quickest route is to consult the owner’s manual for your exact trim and year, or schedule a quick diagnostic at a Honda service center.
Relearn procedures
Relearn methods may include driving at sustained speeds above a certain threshold (often around 30–50 mph) for several minutes, using a dedicated TPMS relearn option in the vehicle’s settings, or requiring a tool at a service shop. Because methods differ, follow the procedure specified for your exact Honda model to avoid a lingering warning.
When to seek service
If you cannot confirm all tires are at the correct pressure, if any tire shows damage or a slow leak, or if the TPMS light stays on after a relearn, schedule a diagnostic with a tire shop or Honda dealership. A persistent TPMS warning may indicate a faulty sensor, failing battery, or an ECU fault that needs professional attention.
Summary
A TPMS light on while tires look fine usually points to actual underinflation, a failing sensor, or a need to relearn the system after maintenance or temperature changes. Start with a precise tire pressure check, inspect for leaks, then use a diagnostic scan to read TPMS codes. If a sensor is faulty or a relearn is required, have the proper service performed, especially on a Honda where model-specific relearn steps may apply. Regular verification of tire pressure and sensor integrity can prevent unexpected warnings and keep you driving safely.
How to clear TPMS light Honda?
Pressure you'll need to reset. The system to do so your vehicle must be in park with the parking brake set if necessary. And the ignition should be on on the touchcreen.
What are common TPMS problems on Hondas?
Common TPMS Error Codes
Some common error codes you might encounter include “TPMS sensor not detected,” “TPMS sensor malfunction,” or “TPMS system failure.” These codes can appear on the dashboard or infotainment screen, or they may require a specialized scan tool to retrieve.
What if my TPMS light is on but the tire is okay?
A recalibration or reset of the TPMS system is often required in these situations. This can be done by following the instructions in your vehicle's owner's manual, or you may need to take the vehicle to a professional to reset the system using specialized tools.
Why is my tire pressure light on when my tires are fine on my Honda?
If your Honda TPMS light is on and flashing, it could mean that the sensor battery is failing or that the tire pressure sensors are malfunctioning. Whatever the issue is, you should bring your vehicle into our Service Center as soon as possible. Our expert technicians can quickly diagnose and correct the problem.
