The light on the tyre pressure monitoring system, which is shaped like a horseshoe with an exclamation point in the middle, usually indicates that you have a low-pressure tyre.
When your TPMS light comes on, take it to a local service center like ours, where qualified technicians have the advanced technology needed to diagnose and fix all parts of your Chevrolet car, including tyre problems. If you want to learn how to reset TPMS without key fob, follow these steps:

How To Reset Tpms Without Key Fob?
The low tyre pressure indicator on your car (also known as the TPMS light) should switch off once you’ve filled your tyres to the necessary PSI pressure (pounds per square inch). There are times, though, when it just does not work. The indicator doesn’t always reset, leaving you with an obnoxious orange light or, in some newer vehicles, a continual notification indicating your tyre pressure is low on the display.
If you’ve checked the tyre pressure in each of your tyres, including your spare (yes, spares typically have sensors as well), and the warning light still won’t turn off, consider the following methods to reset it.
1. Drive For 10 Miles At 50 Mph
The basic mechanism is to drive roughly 10 miles at 50 mph. If possible, use the cruise control feature to maintain a steady speed. Sensors in some vehicles are reset at higher speeds than in others. When you’re finished, park the car and turn off the engine. When you start it again, the light should switch off.
2. Press The TPMS Reset Button On Your Vehicle
Each tyre has a sensor fitted. A simple sensor system reset is sometimes all that is desired. Your owner’s manual should show you where to find the TPMS (Tire Pressure Monitoring System) reset button.
Procedure
- Turn the ignition key to the “on” position, but do not activate the vehicle.
- Simply hit the reset button (in certain cases, this is located under the steering wheel) until the luminance blinks three times.
Release the button. - Allow the computer to re-calibrate all of the sensors by starting the car and letting it run for 20 minutes.
- Remove the key from the ignition.
3. Inflate And Re-Inflate Tires
Some automobiles, such as the Toyota Prius, have a tire pressure range of three pounds or less. If the reset button does not work, elevate each tyre to its prescribed PSI plus three, then compress all of the tyres to near zero. Re-inflate all of the tyres to the sidewall pressure specifications. Don’t forget about the spare tire; it’s likely to have a sensor as well. Drive a few miles at 15 mph to restart the sensors.
4. Disconnect And Reconnect The Battery In The Vehicle
Your car’s internal computer examines all of the vehicle’s sensors (including tire pressure sensors) and determines what to do with the data. The computer in your car, like your home computer, may periodically experience an unidentified malfunction. Disconnecting and reconnecting your car’s battery is a quick and straightforward way to reset your PC.
Procedure
- Open the hood of your car.
- Disconnect the negative battery cable once you’ve located the battery. It will be necessary to use a socket for this.
- After the battery has been detached, start your vehicle and push the horn for three seconds. Any remaining energy in the vehicle’s electrical system will be drained.
- Remove the negative battery cable and reconnect it.
Frequently Asked Questions:
Here are some frequently asked questions about Reset Tpms Without Key Fob:
1. What Are The Three Types Of TPMS Relearn Processes Most Commonly Used?
Auto relearn, stationary (manual), and OBD is the three types of relearning methods. Some cars may employ a mix of two or more types of relearning. Indirect TPMS systems use an initialization approach that may necessitate the use of a TPMS tool to determine the actions required to reset the system.
2. How Do You Manually Reset A Tire Pressure Monitoring System (TPMS)?
Turn the key to the “on” position with the vehicle off, but do not start it. Hold down the TPMS reset button for three seconds until the tyre pressure light blinks three times, then let go. Start the automobile and let the sensor refresh for 20 minutes. Typically, the TPMS reset button is found beneath the steering wheel.
3. Is It Possible To Reset The TPMS Using OBD2?
If you have a good OBD2 scanner, you may also reset the TPMS light with a diagnostic scanner. Before making a purchase, verify sure the tools are suitable for your car.
4. Why Isn’t My Tire Pressure Monitoring System (TPMS) Relearning?
If the TPMS system does not reset after following all of the instructions correctly, there may be an issue with the sensor and the vehicle’s ECU, especially in larger trucks like the F-Series. If the sound does not chirp during steps 6 or 8, the retrain operation was unsuccessful.
5. What Are The Three Types Of TPMS Relearn Processes Most Commonly Used?
Auto relearn, stationary (manual), and OBD is the three types of relearning methods. Some cars may employ a mix of two or more types of relearning. Indirect TPMS systems use an initialization approach that may necessitate the use of a TPMS tool to determine the actions required to reset the system.
6. How Do TPMS Sensors And The ECU Communicate?
Tire pressure sensors are likely to interact with your vehicle’s computer (the ECU) via a wired connection, which is how many other sensors communicate with the ECU. The tyre pressure sensor, on the other hand, transmits data to the ECU using low-frequency radio waves.
7. Is It True That TPMS Sensors Are Wireless?
All of this information is typically sent wirelessly by a direct tyre pressure monitor. A serial number is assigned to each sensor. This is how the system distinguishes not just between itself and other vehicles’ systems, but also between pressure measurements for each specific tyre.
Conclusion
A driver can be irritated and distracted by a trapped low tyre pressure light. It puts drivers and passengers in danger when it malfunctions since it no longer reliably delivers tyre inflation information. The problem of how to reset Tpms without key fob is a serious problem. The sooner you fix it, the sooner you can get back on the road safely. Best of luck!
