I have a 2005 lexus ls430 ultra luxury. My tire low pressure warning keeps coming on about every 2 or 3 days. I reset it because after checking the tire pressure, none of the tires are low. I think that i am resetting it properly but i am not sure. I turn the ignition to the on position and hold down the reset button for around 5 seconds and the warning goes off.
.
Any suggestions.?

 

Give this a try...


While you're at it, go ahead and check pressure on the spare tire also. This has nothing to do with the tire pressure warning light, but I bet the spare tire pressure is low too.

 

Thank you. I was not waiting for the initial message. Working great.
