Does TPMS sensor give actual pressure

Hi. I was wondering if the G37's TPMS tell us teh pressure of teh tire as well. Our acura does which is nice and i've driven a m45 that shows it as well on the center screen. Is this in a special setting anywhere?

No it doesn't. No pressures at all. It doesn't even indicate which tire has a problem or how low it is. It's a very **** poor system. The system on Nissan models even tells you the actual pressure at each corner, but our Infiniti doesn't. Embarrassing.

The M45s do. I wonder if the TPMS sensors from the m45 would give that info in some sort of way.

Furthermore, you cannot even reset the TPMS system unless you take it to the dealer; most modern cars offer a TPMS reset button you use when you switch TPMS sensors.

It's not the sensors... It's the computer that's processing the signals from the sensors.

Ah. didnt know that. So our sensors do send out the psi. Just wish we had a program that had it. I wonder if its built in like the camera sensors that are built in for viewing in all directions that pops up every once in awhile when you shift from reverse to netrual quickly a few times.

They have to sent pressure readings so that the computer knows when to alert you they are low.

I was wondering the same thing tonight. I got the low pressure warning and so I spent 20 to 30 minutes trying to scroll through menus, sub-menus, etc. to see what was going on. My 2006 M35X would give a nice bright pic on the nav screen with an exact reading for each tire. I assumed a three year newer G would have the same. You know what they say about assume....

In the garage now and I will have to pull the tire gauge out tomorrow and see what's up.

The non luxury Z has individual pressure readings. For that matter, my wife's crappy base model Chevy Malibu company car has it. It seems to be one of those details of cost cutting where Infiniti really dropped the ball big time in their quest to be viewed as equals with other luxury brands.

hate to say it my acura rdx has it.
not only does it give you tire pressure so you can figure out if you have a long term problem.plus displays what wheels are getting traction,could be bigger.
and that vehicle is 11k less.
infiniti screwed the whole system up, I can give voice commands for a ton of different things,just not tire pressure.

Question Tire pressures

Didn't want to start a whole new thread on this. First off I have to admit that I NEVER check tire pressures. However my TPMS came on so I went into the garage, tire pressure gauge in hand. Door sticker says 39lbs all around as a cold temp. Temp is garage is about 13 (55 Fahrenheit) and car has not moved today. All tires are reading 32lbs?? Does that sound right? All four to be low at the same time? Fall weather is affecting them?

Love hear some comments.

Shane D

PS: Stock tires that came with car and it is a 'vert.

It's not stated anywhere in the manual. My personal experience has been at about 7 or 8 PSI low.
