i have a 2005 350z enthusiast model with the 17in rims. and in the digital gauge it doesnt tell me the PSI reading of my tires. why is that? shouldnt it tell me?

 

^^ You have TPMS sensors in your wheels, but only get the “idiot” light and no actual pressures in your LCD display?

Is that your question? (Please forgive me if I missed the question.)

how can i tell if i have the tpms sensors on my wheels they r the stock 17in rims. and all i am saying nothin is displayed on the LCD screen except "- - -"

 

If your LCD screen displays "---", you may not have the TPMS sensors in your wheels.

If the sensors are installed in your wheels, they are not working (most likely installed in the "wrong" order) and you need to have your Nissan dealer "flash" the sensors. They use a handheld device to do this. It takes 2 minutes.

"DIGITIAL" ?

nice...

 

Huh? ...probably a typo, but we know what he means.

Boy is "digital" in all-caps hard to look at.

how can i check if i have the sensors on my wheels?

 

The sure way is removing the wheel, and then the tire, and looking at the inside of the wheel.

Or, take the car to your dealer and have someone there try flashing the sensor. If there’s no reading, then there’s no sensor in the wheel.

my passenger rear sensor will cut out once in a while and give me the -- reading.

 

if i dont have it do u know about how much it will cost me to have it. bc if it doesnt cost that much im willing to get it.

 

You can simply replace the bad sensor. That does require calibrating all your sensors (the dealer does that).

If your sensors are old, it might be a battery issue. In this case you may want to replace all four sensors instead of waiting for them to fail one by one. This might be a better solution since each replacement requires recalibration/flashing by your dealer.

Ask first, then you can decide. Dealers charge anywhere from nothing to $75 (or even more... but it's a rip-off if it goes much higher since it's a 5 minute job).
