The Tire Pressure Monitoring System (TPMS) is a crucial safety feature in modern vehicles, including the Toyota Highlander. It keeps track of the tire pressure and alerts the driver when it falls below the recommended level. However, sometimes the TPMS can malfunction, causing the warning light to turn on even when the tire pressure is normal. In this article, we will explore the common causes of TPMS issues in Toyota Highlanders and provide step-by-step instructions on how to reset it.
One of the most common causes of TPMS issues in Toyota Highlanders is a dead battery in the TPMS sensor. The TPMS sensor is a small device located inside the tire that sends a signal to the car’s computer. If the battery is dead, the sensor cannot communicate with the computer, triggering the warning light. Another common cause is a damaged sensor due to road hazards or wear and tear.
Resetting the TPMS in a Toyota Highlander is a relatively simple process that can save you a trip to the dealership. It involves pressing a button or following a series of steps, depending on the year and model of your vehicle. In the next section, we will provide detailed instructions on how to reset the TPMS in a Toyota Highlander, so you can get back on the road with peace of mind.
Understanding TPMS in Toyota Highlander
The Tire Pressure Monitoring System (TPMS) is an essential component of the Toyota Highlander’s safety system. It is designed to alert the driver when the air pressure in one or more tires is low. The TPMS is a safety feature that can help prevent accidents caused by underinflated tires.
The TPMS in the Toyota Highlander works by using sensors mounted in each wheel to measure the tire pressure. If the pressure in one or more tires drops below a certain level, the system will alert the driver with a warning light on the dashboard.
There are several reasons why the TPMS warning light may come on in a Toyota Highlander. One common cause is a drop in tire pressure due to a puncture, leak, or other issue. Another possible cause is a malfunction in the TPMS system itself, such as a faulty sensor or wiring problem.
If the TPMS warning light comes on in a Toyota Highlander, it is important to take action to address the issue. Driving on underinflated tires can be dangerous and can cause damage to the tires and wheels.
To reset the TPMS system in a Toyota Highlander, the driver must follow specific steps outlined in the owner’s manual. These steps may vary depending on the year and model of the vehicle. It is essential to follow the instructions carefully to ensure the TPMS system is reset correctly.
In summary, the TPMS in the Toyota Highlander is a critical safety feature that alerts the driver when tire pressure is low. If the warning light comes on, it is essential to address the issue promptly to prevent accidents and damage to the vehicle.
Causes of Toyota Highlander TPMS Malfunctioning
Sensor Battery Failure
One of the most common causes of TPMS malfunctioning is a sensor battery failure. TPMS sensors use batteries to transmit data to the car’s computer system. Over time, these batteries can die, causing the sensors to stop working. When this happens, the TPMS warning light will illuminate on the dashboard.
Tire Pressure Imbalance
Another common cause of TPMS malfunctioning is tire pressure imbalance. If the tire pressure in one or more tires is too low or too high, it can cause the TPMS warning light to turn on. This can happen if the tires are not properly inflated or if there is a leak in one of the tires.
System Fault
A less common but still possible cause of TPMS malfunctioning is a system fault. This can happen if there is a problem with the car’s computer system or if there is a wiring issue. When this happens, the TPMS warning light will turn on and may stay on until the issue is resolved.

It is important to note that TPMS malfunctioning can also be caused by external factors such as extreme temperatures, electromagnetic interference, or physical damage to the sensors. If you are experiencing TPMS issues, it is recommended to have your car inspected by a professional to determine the root cause of the problem.
How to Reset Toyota Highlander TPMS
Resetting the TPMS (Tire Pressure Monitoring System) on a Toyota Highlander can be done manually or with a TPMS reset tool. This section will cover both methods.
Manual Reset
To manually reset the TPMS on a Toyota Highlander, follow these steps:
- Turn the ignition switch to the ON position.
- Press and hold the tire pressure warning reset switch until the tire pressure warning light blinks three times.
- Release the switch.
- Wait a few minutes for the system to complete the initialization process.
After completing these steps, the TPMS should be reset. If the tire pressure warning light does not turn off, it may be necessary to check the tire pressure and adjust it to the recommended level.
Using a TPMS Reset Tool
Using a TPMS reset tool can make the process of resetting the TPMS on a Toyota Highlander faster and easier. Here are the steps to follow:
- Turn the ignition switch to the ON position.
- Connect the TPMS reset tool to the OBD II port under the dashboard.
- Follow the instructions provided by the TPMS reset tool to reset the TPMS.
After completing these steps, the TPMS should be reset. If the tire pressure warning light does not turn off, it may be necessary to check the tire pressure and adjust it to the recommended level.
It is important to note that if the TPMS warning light continues to stay on even after resetting the system, there may be an underlying issue with the TPMS sensors or the system itself. In this case, it is recommended to take the vehicle to a certified Toyota technician for further diagnosis and repair.
Preventive Measures for TPMS Issues
It is always better to prevent TPMS issues from happening than to fix them after they occur. Here are some preventive measures that car owners can take to avoid TPMS problems.
Regular Tire Pressure Check
Regular tire pressure checks are essential for maintaining TPMS functionality. Proper tire pressure ensures that the sensors receive accurate readings and that the system functions correctly. Car owners should check their tire pressure at least once a month and before long trips. They should also ensure that their tires are inflated to the recommended pressure levels specified in their vehicle’s owner’s manual.
Timely Battery Replacement
TPMS sensors use batteries that can last up to 10 years. However, battery life can be affected by several factors, such as extreme temperatures, moisture, and exposure to harsh chemicals. Car owners should replace their TPMS sensor batteries every five to seven years or when the battery indicator light appears on the dashboard. Replacing the batteries on time ensures that the sensors continue to function correctly and that the TPMS system provides accurate readings.
