TPMS Light Honda: What Does It Mean & How To Fix It

A vigilant Honda driver’s eyes may sometimes catch an unexpected warning light on the dashboard: the Tire Pressure Monitoring System (TPMS) alert. The TPMS plays a vital role in maintaining optimal vehicle performance, safety, and efficiency.

Essentially, it’s your vehicle’s way of telling you that your tires need some attention – that the tire pressure isn’t quite right. This article will delve deeper into what triggers this light, what to do if it illuminates, and how to reset your Honda’s TPMS.

What To Do If The TPMS Light Is On?

When the TPMS light illuminates your Honda, it’s a clear indication that at least one of your tires is underinflated. This could pose safety risks, as improperly inflated tires can affect vehicle handling, increase tire wear, and potentially lead to tire failure. Your immediate response should be to safely pull over and inspect your tires.

If possible, inflate the tires to the recommended pressure (typically found in your vehicle’s user manual or on the driver’s door jam sticker). However, in the case of a drastic pressure drop or visible damage, it’s safer to replace the tire or seek professional assistance.

How To Reset The Honda TPMS

Resetting your Honda’s TPMS isn’t typically a complicated process, but it can differ slightly depending on the vehicle model. Generally, once the tire issue has been resolved, driving the vehicle for a few miles at a moderate speed may automatically reset the system.

Alternatively, for models equipped with a TPMS button (often located on the dashboard, to the left of the steering wheel), you can manually reset the system. After turning on the ignition, press and hold this button until the TPMS indicator blinks twice, signifying a reset. Remember to consult your vehicle’s user manual or a professional if you have any doubts.

What Triggers A TPMS Light?

Several factors can trigger the TPMS light on your Honda. The most common is low tire pressure, typically caused by a slow leak, a puncture, or a significant change in temperature.

Additionally, TPMS sensors have batteries that can eventually die, causing an inaccurate reading and triggering the light. Furthermore, if you’ve recently had new tires or wheels installed, or if the TPMS was not correctly initialized after tire rotation, the system might fail to accurately monitor the tire pressure.

How Do I Turn Off The TPMS Light?

Turning off the TPMS light involves addressing the issue causing the alert. If the light is on due to low tire pressure, inflating your tires to the correct pressure should resolve the problem. If the TPMS sensor’s battery is dead or if there’s a problem related to tire installation or rotation, you will likely need professional assistance to rectify the issue.

Once the underlying problem has been fixed, the light should automatically turn off after a short drive. However, you can also manually reset the TPMS as described earlier if needed.

How Do I Fix My Honda TPMS?

1.     Check Tire Pressure

The most common reason for a TPMS warning is incorrect tire pressure. In this case, you’ll need a tire pressure gauge to check the pressure of each tire. This can be a simple, handheld device or a feature of an air pump at a gas station.

The correct tire pressure for your Honda model will be listed in the vehicle’s user manual or on the sticker inside the driver’s door jam. Checking tire pressure isn’t just about ensuring you’re not under the recommended PSI. Overinflation can be just as detrimental, causing uneven tire wear and a potentially harsh ride.

2.     Adjust Tire Pressure

If your tire pressures are not at the correct level, adjusting them is the next step. For underinflated tires, add air until they reach the recommended PSI. Conversely, if a tire is overinflated, slowly release air until you reach the appropriate pressure.

Adjusting tire pressure isn’t a complex task but requires attention to detail, as incorrect pressures can negatively impact vehicle handling, tire lifespan, and fuel efficiency. Once the pressure has been adjusted, the TPMS should reset itself after a few minutes of driving.

3.     Inspect Tires for Damage

In case of a visible puncture, you’ll likely need to have the tire repaired or replaced, which should be done by a professional to ensure safety and performance. Furthermore, remember to check the sidewalls for bulges or bubbles – these could indicate a weak spot that could lead to a blowout.

4.     Replace TPMS Batteries

TPMS sensors are powered by batteries that eventually run out. If your TPMS light comes on and stays on, even if the tire pressure is correct and there’s no visible tire damage, a dead battery might be the culprit.

Replacing the battery involves removing the tire and disassembling the TPMS sensor, tasks typically better left to professionals.

5.     Reprogram the TPMS

If you’ve recently replaced a TPMS sensor or swapped wheels on your Honda, you may need to reprogram the TPMS. This allows the system to recognize the new sensor or wheel.

This process often involves using a specialized tool and following specific procedures that vary from model to model, so it may be best to consult a professional or your vehicle’s manual.

6.     Check for Faulty Wheel Sensors

If the TPMS light continues to illuminate even after checking and adjusting tire pressure, the issue could lie with the TPMS wheel sensors.

These sensors can malfunction due to age, damage, or corrosion, leading to inaccurate readings. This problem will require a professional for diagnosis and replacement.

7.     Reset the TPMS

After resolving the issue that caused the TPMS light to come on, you may need to reset the system manually. While some vehicles will automatically reset the TPMS after you drive for a while, others require a manual reset.

You can do this by locating the TPMS reset button, usually found on the dashboard, and holding it until the light blinks twice.

8.     Seek Professional Help

If you’ve tried all of these steps and the TPMS light is still on, it’s time to consult a professional. They will have specialized equipment that can diagnose more complex issues that may be causing the light to stay on.

It’s better to err on the side of caution when it comes to your vehicle’s safety features.
