my tire pressure light is on
and i checked all my tires and they are fine
i dont kno what to do

 

you might want to re-calibrate the wheels again

 

how would i go about doing that?

 

you mean balance?


and no your fine. if you checked the pressure in all the tires and they are fine. then open your glove box, and hit the reset button for your TPS and your good to go

 

Once you reset the TPS.. If it comes on again, then balance those bad boys!

 

Does it really detect whether or not the tireds need balancing? becuase mines always on I've just given up on turning it off.

 

ya like all my tires are at 29psi there supposed to be at that right?

 

the TPS = Tire Pressure Sensor. It runs by a wire that detects the speed (rotation) of the tire. If you have less pressure in one tire, compared to the others, the light will trip because the system is detecting one wheel moving at a different speed then all the others.

it can also trip if the that sensor wire has been damaged.


so if yours keeps tripping murr, and all your tires have the same pressure in them (i like to run 32 or 35), you have a problem with your system, and a wire was probably damaged.

 

29 is low... bump them bad boys up to between 32 - 35.

 

well thanks for the response I will go get that and my sunroof checked out while I'm still under waranty

 

not to get off topic. but whats wrong with your sunroof?

 

if u have a 2007 and have aftermarket wheels thats your problem right their!!!

 

o ya im gonna try adding some more pressure to them

because i got 29psi after driving for an hour on a really hot day

so its prob lower than that right now in my garage

Section C #15

 

what year tC do you have? if it's an '07, the TPMS are built into your valve stems. consequently, if you have aftermarket wheels, your TPMS light will ALWAYS be on unless you transferred the valve stems to your new rims. if you have and '05 or '06, the TPMS reads off of ABS. if you're still on stock wheels, try pressing the reset button inside the glove box and if it still doesn't work, even after the tires are at the recommened PSI, i'd say call the dealer and have them look at it.

 

rgeezyinTC... your 100% wrong. if you know nothing about the system... why reply with false information?

and murr i figured. all the dealer is going to do is clean the track and re-lubricate it. but its free for them to do it under warranty, so i agree with you gong back to them and making them do it. haha

 

very good point. i forgot to ask if it was an 07. but i believe he has factory wheels.

there is a way to trick the TPMS with newer cars that have aftermarket wheels that dont have enough room for the TPMS though. It wont be a working system, but it will turn the light off. if you put all the sensors in your spare tire, all the sensors will read the same tire pressue, so your light will go off. but like i said, it wont be a working system.

 

ahh now there's a good idea. unfortunately that would have cost me an extra 80-100 dollars to get my old tires dismounted from my stock wheels, so i passed it up. maybe i'll just take apart the gauge cluster and kill that specific LED

 

you could do that too. haha
