Tire Pressure Information on Display Screen (1 out of 4 showing a PSI)

[johnnysnok]

2010 QX56

While driving, when I hit the information button and go to tire pressure only 1 tire shows a PSI the rest are blank on the display screen.
Yesterday I had my sensors tested in the tires and was told all of them were working by a Goodyear tire mechanic.

Has anyone experienced this or may know what the problem is? I cannot find much in the manual or on the web.

Thanks

if you see *** next to the psi on the screen the tpms's are not communicating with the car. the most obvious reason is they are inoperative and/or you may have an issue with the head unit not reading the signal.

what prompted you to hit the tire info? did you hit something on the road? or just random curiosity?

did you just buy the car? how long have you had it? have the pressure info every worked before?

were you driving for at least 3-4 minutes before you pressed the info button? just making sure.

check for ay codes at the obd port?

Thanks for the quick reply, I have had the car for almost 8 years, all of the sensors did work, i cannot begin to say the last time i checked the PSI on the dash. I just happened to check it on the way to have my tires rotated yesterday and 3 of them had the *** next to them. I was surprised the tire dude said they were all registering on his hand held machine.
I was driving for around 15 minutes while checking the pressure.

The flat tire/ low pressure icon on my dash seems to be working? It did come on about 4 months ago when 1 of my tires needed air.

I am not able or know how to check for any codes.

just sounds like the sensors in the wheel are bad. the batteries die in them after some years pass.

you can hit up an autozone or similar location and they can check the obd port. your "tire dude" should also have one.
you can get a dongle off the internet and get an app in the app store and use those items to check for codes and in some cases clear the check engine lamp.

its tough to say over the internet. id go to a nissan shop or another tire shop and get a 2nd opinion.
