The Honda TPMS light is on but the tires are fine. Here’s why

Driving a Honda car and facing the problem of the TPMS light coming on, despite knowing that the tires are in good condition can be a frustrating experience.

Understanding this issue and finding its solution to ensure safe driving is essential.

What is TPMS?

TPMS stands for Tire Pressure Monitoring System, which is an electronic system designed to monitor tire air pressure levels.

In case of low or high tire pressure, it sends alerts to the driver through warning indicators on the dashboard.

Why Does The TPMS Light Come On Even When Tires Are Fine?

If your Honda car’s TPMS light comes on even when your tires are good, then there could be multiple reasons such as:

1) Faulty sensors

Sometimes due to faulty sensors, the TPMS warning light may come up even if all tires have proper pressure. It could happen due to malfunctioning sensors or corroded battery connections in sensors.

2) Low atmospheric temperature

In colder seasons like winter, we often notice low-pressure readings because cold air contracts volume-wise increasing air density resulting in lower tire pressures than usual. Hence during such adverse weather conditions, drivers might observe false triggers by TPMS systems

3) Issues with the Valve stem

Valve stems seal each wheel from outside weather affecting inflation but also house a core schrader that connects sensor leads beneath the wheel’s open end caps.

Over time these valve stems start degrading causing air leaks into tires hence losing inflated gas inside which prompts tpms lights whereas there’s certain tolerance before the system illuminates the indicator

4) Electrical Issues

Another reason for this problem could be electrical issues related to wires connecting the control module and sensors.

How To Fix A Honda Car’s TPMS Light?

Here are some possible solutions :

1) Check Tire Pressure

The first step is to check the tire pressure with a gauge and compare it with recommended levels in the manuals. Ensure you fill the air up to desired psi using additional tools like a portable compressor.

2)Inspect Sensors

If the tire pressure appears fine, then send your car for servicing where technicians inspect sensors & find out whether they need repair or replacement.

3) Replace Valve Stems

If there are no sensor issues, valve stems may be causing false-positive readings on the TPMS light. Replace them if found defective/worn out

4) Check Fuses

It’s recommended that fuses to circuits controlling TPMS light are checked when the rest components are working fine. If any fuse issue is seen rectify it.


Do not ignore the TPMS warning light as it can lead to dangerous situations like sudden blowouts, or loss of traction due to underinflated tires resulting in accidents so always solve this issue promptly.

To ensure safety while driving a Honda car, understanding the reasons behind TPMS failures is crucial. Keep your car well-maintained and follow all maintenance requirements specified in the manual to prevent these problems from occurring unexpectedly.
