TPM sensor

[H3 HUMMER 11]

Hi, whenever it rains, The TPM says the the tire low. When it stops raining, i never get the message. On a sunny day, i also never get the message. Have you seen this on your H3?

Can you duplicate it by hosing down the tires with a lot of water?
No, I have not ever heard of this one.

When it rains the ambient temp drops, therefore lowing the temp of the tires. Lower temp causes the pressure in the tire to drop setting off the monitor.

Increase your cold air pressure in the tires and the problem should be solved.

Mine have a max pressure of 44 and I normally run 38 to 40 cold

First check that your tires are at recommended pressure when cold (see sticker on drivers door). Should be no need to overinflate.

Hi,

Thanks for all the response. I aired up the tire to recommended pressure and the light hasn't gone off yet.

My TPM light kept coming on, even after I checked the pressure and all tires were OK. I later found a screw imbedded in one of the tires. Had it removed and had the tire patched from the inside. The light hasn't come on since.
