Low tire pressure indicator light comes on when tire pressure is correct

The TPS sensor may be dirty or defective...be sure all tires are above 33 psi...

First, check the tire pressure of the spare. If all tires are properly inflated, then one of the sensors are bad and must be replaced.

That signal is from your tire monitoring sensors, telling you that there is air pressure difference between tires. The tire pressure should be same in all tires.

You will need the dealer to scan the system for the problem that giving you a false indication of low pressure. Also make sure the spare has the correct pressure.

The LOW TIRE PRESSURE warning light will come on when the pressure is 25% below the manufacturer's recommended pressure. If I recall correctly, the 2007 Sonata has a manufacturer's recommended tire pressure of 30 psi. There is a tire label (sticker) on the inside driver's door jamb ('B' Pillar which tells you what the manufacturer's recommend tire inflation pressure should be. Once you have that value, you can calculate 25% of that & find the pressure at which the warning light should come on. NOTE: The TPMS (Tire Pressure Monitoring System) does not continually nor constantly scan the sensors in the wheels for this information - once every 3 to 10 minutes.

this is your low tire pressure indicator light , it means one of you tires air pressure is lower than it should be , check you tire pressure on all tires and inflate as needed once they are correct than the light will go out , keep an eye on the tire that was low , you may have a slow leak

definetly tire prssure low light. you can reset it by scrolling through the mileage and trip meter once you get to the screen for the tire preesure monitor hold the button down till it flashes and it will reset. make sure you check all your tire pressures first.

Some cars with tire pressure sensors also sense the pressure in the spare. Have you checked the spare?

if u have the right tire pressure in the tires the light will go out . but sometimes you have to put 5 to 10 miles on the car to reset

I took my car to the dealer and they solved it for me, I am not sure what exactly they did, but I know it involved me changing some tires.
