Why does my tire pressure keep coming on?
Why does my tire pressure keep coming on?
As the name suggests, your tire pressure monitoring system (TPMS) light coming on typically means your tire pressure is low. However, sometimes it turns on due to a drastic drop or rise in temperature. If your light stays on, it could be due to a tire puncture causing a slow leak of air.
What does a flashing tire pressure indicator mean?
A TPMS warning light that illuminates solid and remains solid usually means that one or more of the tires has low air pressure and needs to be inflated to the correct placard pressure. The flashing light can mean the sensor is damaged, missing, or has a dead battery and needs to be replaced.
How can I tell if TPMS is working?
After starting a vehicle, a TPMS icon will turn on for a few seconds; however, if it stays on, it indicates that one or more of the tires on the vehicle are at least 25% below the recommended pressure. If the light flashes for approximately one to two minutes, it indicates there is a malfunction in the TPMS system.
What does a low tire pressure warning light mean?
The wheel sensor requires replacing (in an Indirect Tire Pressure Management System). In an Indirect system, if the wheel sensor has gone bad, the ABS Warning Light also illuminates. In each case, it means the vehicle needs to go to a certified mechanic. The mechanic can detect and patch the leak or replace the tire.
How does the tire pressure indicator work on a Ford?
This indicator also illuminates momentarily when you switch on the ignition, showing that the lamp is functional. If the indicator remains lit while the engine is running or you’re driving, check your tire pressure as soon as possible.
When does tire pressure monitoring system light up?
Typically, a Tire Pressure Monitoring System (TPMS) will illuminate. It happens should the tire pressure drop. It will precisely light up if the pressure drops 25% below the required value. In our case, the TPMS may be issuing false signals. What can you do? There are some situations whereby the tires are not underinflated or flat.
What does it mean when your TPMS warning light is on?
So check your tires carefully. If your vehicle has a TPMS, it’s probably monitoring the pressure in your spare tire. Therefore, if you get a low tire pressure warning light, and if you’ve checked all four tires that are touching the ground, than you might need to put some air in the spare.
When to use the low tire pressure warning light?
So here’s the short version: Do not use the TPMS warning light as a substitute for regularly checking your tire pressure and keeping it at the recommended level. That’s not its purpose. This low-tire-pressure warning light is set to illuminate at 25 percent below the manufacturer’s recommended pressure.

What do you need to know about tire pressure monitoring?
TPMS Types. Such systems are usually accurate to within 1 psi. Current direct systems use a gauge mounted to the wheel or tire valve. This gauge sends a signal to the car’s computer. How the data is interpreted and displayed in the car with a direct TPMS depends on whether it is a low-line or high-line unit.
Why does my tire pressure light keep resetting?
The light doesn’t always reset, and that can leave you with an annoying orange light or—with some newer vehicles—a constant message on your display that your tire pressure is low.
