and sometimes i see this yellow (><) sign on my cluster.what does it mean? sorry guys noob here/btw i use the search button too. but no luck.

 

Are you talking about the Tire Pressure Monitor System on the gauge? Are you sure your car has it, not all cars have it.

 

my Z didnt

 

Also which yellow sign is this you speak of? Is it the (!) sign? If so that means your tire pressure are low.

 

Do you have aftermarket wheels? If so, they may not have the TPMS sensors installed in them.

Did you read this thread first?

Someone took the sending units out of the wheels and sold them.

 

i know i have it. i have the nismo lmtg wheels when i bought the car. and i reset the gauge,after that i dont see numbers.how do i check if i really have them?

 

I believe the tpms valve stems are made from aluminum, and are also aluminum in colour. That should be a start.

 

There are some excellent photos of the transmitter in the DIY forum.
