I have a 2015 Toyota Corolla LE and I have the tire pressure warning light on my dash. I filled up each tire to 32 pounds but the light is still on. Does it take a certain amount of time or do I have to drive a certain amount of miles for it to go off or does this mean there something wrong with it? I literally just filled them up.

maybe it's like an CEL warning light
and requires the Pos. + battery terminal be removed momentarily
so that the 'puter can reset/recalibrate ?
that or the tire psi sensors are not calibrated correctly
possibly due to different sized tires being installed ?
The internal psi sensors inside the tires
have individual batteries in each of them
if these die and are not changed when they do...
The warning light may remain on until correction is made.
I'd start by first pulling the battery's Pos+ momentaily
and see if the 'puter resets and turns off the dash warning light.

if your tire pressure sensor were set to 32 about 29-28 the light will come on. if it is at the boarder line riding it and warming the tire up will go away. but when its the right time to check your pressure do so, if it is at 29 then I suggest pumping it to 32psi.
I try not to ignore the tps light b/c the time I did that I had a super low tire and was going flat.

Procedure to recalibrate the TPMS via the "reset" button in the upper left part of the glove box. (only needed to set a new PSI value to check, won't work if unknown new sensors are in the wheels)
As Donabed Kopoian said, let the tires cool down for a few hours before doing this.

- Park the vehicle in a safe place and turn the engine switch off. Initialization cannot be performed while the vehicle is moving.
- Adjust the tire inflation pressure to the specified cold tire inflation pressure level.Make sure to adjust the tire pressure to the specified cold tire inflation pressure level. The tire pressure warning system will operate based on this pressure level.
- Turn the engine switch to the “ON” position (vehicles without asmart key system) or IGNITION ON mode (vehicles with a smartkey system).
- Press and hold the tire pressure warning reset switchuntil the tire pressure warning light blinks slowly 3 times.
- Vehicles without a smart key system: Wait for a few minutes with the engine switch in the “ON” position and then turn the engine switch to the “ACC” or “LOCK” position. OR Vehicles with a smart key system: Wait for a few minutes with the engine switch in IGNITION ON mode and then turn the engine switch off.
I was under the impression the cutoff point is approx 25%. So if you are running 32psi, the dash light won't trigger until it drops 8psi to 24-25psi. But you are saying the threshold is about 4psi?
I top off my tires fairly regularly so I don't see 4-5 psi drops and can't confirm if the threshold is 4 psi. I did have one deflating tire (screw) and by the time the dash light went off, it was sidewall finger soft like it had lost 8-10psi or more.
