anybody know what is causing this problem?

the pressure is 31/31 31/31

 

aftermarket wheels?

 

its cold

 

no everything is stock.

 

so psi @ 31 will cause the lights stay on? it was around 27 last night

 

cold weather can affect you tire pressure. If it still stays on, you might have a faulty sensor. Bring it to the dealership in that case or get a new sensor.

 

okay thanks for the straight answer.

 

put your psi at 36-38 you should be fine for a while where you live. light wont go off immeditaly takes a few minutes of riding on them to recaculate

 

what optimum tire pressure do you guys keep?

 

35 PSI

 

I am experiencing this problem as well...the other day my pressure indicator came on out of the blue and will not go off. At a glance the tires appear to look fine, I haven't checked the pressure yet though because I don't have a guage...the day this happened was the first really cold day we've had around here, would that be enough to set it off? Is this a common problem with 350Zs?

 

i think the sudden change of cold temperature is causing this problem. mine got turned off today . and pressure was 29/31 30/31

 

Just raise the PSI, 35-37 is where it should be. I believe it is 35.5 in the manual as well as what thiry5ounces pointed out before, it will take awhile for the computer to recalculate. Make sure you use another tire pressure gauge, other than the one on the gauge inside the car.

 

is this the (!) light that comes up? mine came up today, was doing some searching and found this thread....as stated above it was a very cold day this morning as well.......anyone know if (!) is the light for tire pressure? or what else it is?? TIA

 

some1? any1?

 

Yea that light means your tire pressure is low or it isn't getting a good reading

 

thanks

 

Tire pressure changes with air temp. Your gauges are doing exactly what they are supposed to. With OEM wheels on 03 & 04s you should be at 35 PSI.

Look up recommened pressure in your manual or its listed somewhere in your Z (forgot where at the moment).

 

The Low Pressure warning comes on at 28psi. Stock wheels and tires should be at 35 psi.

 

My low tire pressure warning light came on which caused the (...) thing to appear in my main cluster. I filled up the pressure but the light wouldn't go off on my main cluster until I changed the display on the mini gauge (the one that tells you what the pressure is of all your tires).
