If your low tire pressure light is on even if the tire pressure is fine, you may need to reset the TPMS. It can also be due to a faulty TPMS sensor. However, the sensor battery might also be dead or the TPMS receiver could be damaged. If you have an indirect TPMS system, the problem could be due to the loss of traction. Here is some more detailed i...
1. Direct
The direct TPMS is used in most cars on the road today. With this design, all four wheels have a sensor that feeds information back to the computer. If the tire pressure gets low, a signal is sent and the alert comes on the dashboard. Because of where the sensors are located, there can be damage to them when driving on harsh road conditions, such as dirt driveways or during service. They also go bad simply because of old age, requiring replacement over time.
2. Indirect
Some manufacturers prefer the indirect system, which doesn’t use a sensor on each wheel. Instead, the TPMS runs from the sensors on the anti-lock brakes. These sensors determine when the rotation speed is slow, indicating that tire pressure might be low. The indirect TPMS is considered more durable than the normal system because it doesn’t fail as often. However, you aren’t going to know if multiple tires are running low since there aren’t separate sensors. Up until now, it’s only been some A...
1. Fill Tire with Air
The most obvious solution is to fill the low tire with the right amount of air. When the light comes on, you should always start by checking the tire pressures. You can compare the reading with the recommended air pressure by looking at the driver’s side door jamb. If the light remains on despite the pressures being right, you have to move on to our other tips. READ MORE: How to Find the Correct Tire Pressure For Your Car (4 Steps)
2. Repair Fault
The repair you continue with depends on what is causing the fault. If you don’t have the equipment to figure out what’s wrong, you should visit a qualified mechanic. If the car needs a simple TPMS sensor, you might spend between $75 and $250 for the part and labor. In most cases, a dead battery will also require a new sensor replacement. If the receiver needs to be replaced, the price is going to be slightly more. If you have the equipment to work on these sensors and receivers, you could per...
3. Reset Light
If the light has come on because there was a problem after wheel rotation or another service, you may just need to reset the light. Most manufacturers have a simple way to reset the warning light. You can find it in your owner’s manual. There might be a reset button in your car’s glove compartment or in the menu of your car settings. However, you need to know how long to press the button and what steps are necessary to get the job done.
You should never ignore the warning given by the TPMS light. If you notice it on the dashboard, you want to stop as soon as it’s safe to ensure that there’s enough air pressure in the tires. If the tires aren’t inflated properly, failure is imminent. The tires could overheat and blow out, leading to a dangerous situation. You also lose control as t...

In this article, we’ll show you how to figure out what the problem is, how to fix it, and how you can reset the light.
Apr 1, 2021 · When the TPMS light comes on – and stays on – at least one of your tires is at a low pressure level. Check the pressure of all of the tires with a gauge and determine the cause of pressure loss and add air or service the tire (s) as appropriate.
