TPS Works but no warning

I found out that my tire pressure warning system has stopped working when I went through the guages display and saw that two tires were down 4 pounds and two were down 5 pounds.

Anyone else have that happen? How can the pressure readouts work but the low pressure warning system not work?

I aired all of them up to 30 and looked at the guages in the DIC again and they were correct.

I believe that the warning light goes on at 25 PSI... lower one of your tires to 22 lbs and see if the DIC warns you when driving.

I just looked it up in the shop manual and you are correct, low pressure warning is issued when p[ressure is between 5 and 25 pounds. Since mine was at 25 on the two lowest tires, no warning was required.

I can't recall for sure but seems to me that this is a change from the 2000 that I had where I got low pressure warnings when the tires dropped to 28 pounds.

Thanks for the info.
