Hey guys, i just want to know if the TPMS use batteries, cos after 40 min the (¡) goes on, and at the display the front tires show (--), in both tires, but just the fronts. It happens every day after 40 minutes.

Can any one help me????

 

mine does the same thing.

I ordered new tpms units to go into my new wheels when they arrive.

 

yes they do. and judging by the symbols you typed is your car 03-04? if so then its been 7-8 years that batteries been running so sounds like its time!

 

Yes; however, the battery is not user replaceable.

 

LOL.. no, there solar powered..

 

dammm... so i need new set, where can i get them new?

 

maybe not new...but you can get a set in the wheels and tires classifieds....

 

It's a sealed unit and the battery cannot be replaced. They have an average service life of 7 yrs before it dies and needs replacement.
