overinflating tires causea "TMPS" service light to come on

[rocket_man]

so i went through the routine of adding air to my tires 2 days ago cause the orange TPMS warning went off and since I didnt know which wheel was low I just started filling the tires up with air. So today all was good until about 15 minutes of being on the highway when the "Service TPMS" light came on. So I am thinking I will turn car off then start it and that will clear the light. Nope, start the car and there the warning light is. So I got to my dads and thought I would re-set the computer by disconnecting the negative battery cable for a couple of minutes. Nope that didnt fix it. Dad had a spare gauge he gave me and the tires were inflated to around 42lbs! LOL

So I deflated the tires to 32psi and then that cleared the service "TPMS Light", once things were right the Kizashi was happy! LOL

I really wish the TPMS would tell me which tire was low and needed air. But since the brakes on my car are so strong they impress me over n over each time I drive, I can over look this minor nuisance. And the brakes on my car are super touchy cold. I think I could send someone into the windshield with them.

Um, a tire pressure gage is <$5. You will easily save that in fuel by makin sure they aren't underinflated

You don't need a digital talking one!
