Hola,

Ive noticed on my 8 that everytime it rains or it gets wet my TPS light comes on once I get out the driveway. Has this happend to anyone here? Its odd maybe something exposed? Tire pressure is fine.

 

Does the TPS light stay on the whole time you're driving or does it go off after awhile

 

That is strange.

 

It will stay on different ammounts of time, may go off by the time I get back home or may take another trip or two.

 

And you tire pressure is okay and stays okay huh? You absolutely sure about that, the answer really depends on that.
You might have a bad TPMS in that wheel. Maybe hairline crack letting moisture in and screwing it up? These are just guesses at this point. When was the last time you had the tire off that wheel?
What tire pressure are you running in that wheel. The TPMS's are set to go off at 26lbs. Is it possible you are right around that and a little low when cool, but by the time the tire heats up, the air expands, and you are above 26lbs? Your tires will gain about what................3lbs when heated up.

 

Pressure is fine, it just happens when I wash the car or it rains. Tire hasnt been off the wheel since I bought the car not too long ago . Dunno but thier about to go my new tires & rims just came in. Im thinking water is getting somewhere its not suppose to.

 

Sounds like it. Are you gonna use the TPMS's on the new rims? If you are, you might want to think about getting one and trying in place of that suspect one. Check out Rosenthal Mazda on the Vendor section, they have the best price I've seen on new TPMS's and tell Tommy, you'd like the new style with the latest grommet. It's better......trust me. Your issue isn't the grommet, but why not get the latest. If not using the TPMS's, don't sell that one or someone might get pissed at ya.

 

lol yeah Imma use em . Might soak down my wheels one at a time and see if it goes off :\

 

Good idea...............watch this.....my psychic ablities tell me it he passenger side rear. Don't ask....let's just see....and "no, didn't have your issue".

 

haha will find out tommorow, now Im making that the first tire I try lol
