A tire pressure monitoring system fault (TPMS fault) means there is a problem affecting the vehicle’s tire pressure monitoring system. Sometimes the light comes on to let you know there is a problem when the tire pressure is too high or too low.
In other cases, it means that an error has occurred in the system. The purpose of the tire pressure monitoring system (TPMS) is to warn when tire pressure is too low. As we all know tire pressure can lead to unsafe driving conditions. TPMS gives the warning with a yellow color indicator. This indicator is situated on the dashboard instrument panel. The indicator looks like a horseshoe. Also, it has an exclamation point.
This indicator has a good history in your car. This is a story based on years of uncertainty about proper tire pressure and the many serious car accidents that could have been avoided if drivers knew their air pressure was low. Even now, it is believed that a significant number of cars hit the road with inflated tires every day. However, proper tire care with TPMS can help prevent many serious accidents. Before this indicator was common, the driver had to get out, sit down, and use a tire pressure gauge to know if the air pressure had reached an unsafe level. With few exceptions, it was the only pressure-testing device available to the average consumer. Then, in response to an increase in accidents caused by under-inflation, the US government passed the Improved Vehicle Recall, Accountability, and Documentation Act (TREAD). Not all TPMS works the same. When the low tire pressure indicator illuminates, it indicates the final step of the indirect or direct TPMS process.
- How do you reset the tire pressure sensor on a Tesla?
Not like other automobiles, Tesla’s always unique. So, they display the time, last pressure of the tire, when measured, and current tire pressure on the touch screen. This has indicated under services in the control panel. Also, the plus point is we can select whether we should display the tire pressure in Bar or PSI. The recommended tire pressure in Tesla is between 40 -45 PSI.
The vehicle sets predetermined Cold Condition Pressure (RCP) targets based on the selected wheel size. Before driving the car, ensure the wheel size is correct, and the TPMS sensors are working. This is called automatic learning.
This is the procedure:
- Go to Touch Screen and turn it ON.
- Go to Touch Controls, Settings, Service & Reset, Tire Pressure Monitor, and Finally, Reset all the Sensors. (It is good to know that the “Reset the sensors” option is on the Wheel Size. Also, an incorrect wheel size may result in a low tire pressure warning. If a tire pressure warning appears, leave the vehicle, close the trunk and all doors, wait until the touch screen turns black, then get back in the car and make sure the correct wheel size is selected before touching reset.)
- Press Reset and Touch OK
- Can you drive with a tire pressure sensor fault?
No, driving with a TPMS indicator is unsafe. It means that one of your tires is not inflated or excessively inflated. You can find the correct tire pressure for your vehicle in your owner’s manual or on a sticker on the door, boot, or fuel filler cap. It can cause excessive tire wear, which can cause it to fail and cause a tear, which is dangerous for you and other drivers on the road. Be sure to refer to your user manual for specific instructions on monitoring your TPMS system, as manufacturers may set their TPMS indicators to operate differently.
- Car Status – Press and Hold one of the scroll wheels and select Vehicle status to view a summary of TPMS information. If pressure values from the previous wheels still display, make sure the vehicle has been stationary for at least 20 minutes before moving on to the next step.
- Road Test – Do a Road test. Automatic learning will start when the vehicle speed exceeds 40km/h (25mph). So, when automatic learning is completed, tire pressure information is displayed for each wheel and any TPMS malfunctioning is cleared. Automatic learning during a test drive can take up to 20 minutes. If the message “tire pressure system needs to be serviced” is displayed after performing automatic learning, try this procedure again and again. If the warning persists after 5 minutes of driving at 40 km/h (25mph), just be sure to call Tesla.
If the light is on, your tires may be low on air, which can cause unnecessary tire wear and possible tire failure. Before driving the vehicle, the correct wheel size and operation of the TPMS sensors should be checked. This is called automatic learning
- What does it mean when it says tire pressure monitor fault?
A tire pressure sensor means there is a problem affecting the vehicle’s tire pressure monitoring system. Sometimes the light may come on to tell it about a problem when the tire pressure is too high or too low. In other cases, it means that there is a bug in the system.
Press and hold one of the scroll wheels and select Vehicle Status to view an overview of TPMS information. Do a road test. Automatic learning will start when the vehicle speed exceeds 40 km/h
TPMS sensors can reset using the vehicle’s touch screen since the reset function is only possible when the car is running. But the critical fact is that only Tesla-certified sensors use when performing this procedure (The Tesla Model S TPMS has a built-in feature that automatically detects a new set of wheel sensors).
- How do you clear the tire pressure monitoring system fault in a Tesla Model 3?
Each tire should be checked monthly when cool and inflated to the recommended pressure, which is printed on the loading and tire information label on the driver’s door pillar (or tire pressure label). Select the correct tire pressure for those tires.
As an added safety feature, your vehicle is equipped with a TPMS system that displays a tire pressure warning on the Touchscreen when the pressure in one or more tires is too low or too high.
Accordingly, when the tire pressure indicator is displayed on the touch screen, to alert you to the tire pressure, stop and check the tires as soon as possible, and inflate them to the correct pressure. Driving on a tire that is not significantly expanded will cause the tire to overheat and may cause tire failure. Inadequate pressure also reduces band efficiency and tire tread life and also can affect the vehicle’s handling and braking ability. After changing one or more wheels (but not after changing a tire), the TPMS sensors are relearning to ensure accurate tire pressure warnings. TPMS sensors reset automatically within 10 minutes when driving at speeds above 15 mph.
