everytime i drive my 350 out, maybe 2 seconds the tire pressure (PSI) light comes on. i took it 2 the dealership already paid 30 bucks (can.) to check out the tire pressure wire, and the light. the dealership said there isn't a problem and they still charged me.
but my light did turn off. but today it came on again, it hasn't even been a week. plz help me if u know anything about this, if it ever happen to you,. thx

 

i'm think its the weather. i live in edmonton alberta, canada. its around 27 C, here.

 

I've read similar posts in the past and this seems to happen with fluctuations in temperature, usually when it is cold outside. If you do a search, you may come up with more info. I don't think its a serious problem though.

 

What are your tire pressures?
