Does anybody else find this some what annoying? If it drops 2 psi it goes off. Found this especially annoying on road trips and when I get in my car and the temp is high 30s or low 40s.

 

Yes. It's a silly system, brought to you by the gub'ment.

I have only had TPMS go off when I had tires below 30psi

 

Mine goes off in fall through winter when temp drops

 

I don't have the TPMS sensors any more so my alarm never goes off. The light comes on when I've been driving for more than 30 minutes continuously but resets when I turn off the car.

 

TPMS are annoying never had them before owning my FX35 and G35 now the lights came on in my FX and all tire are well over 30psi. another trip to the dealership for me

 

I was just wondering about this. It went off, and my tire was low, so I filled it up, but it went off again. At what PSI does the TPMS go off?

 

According to the manual (for 2006 sedan anyway), vehicles with a recommended tire pressure of 30 will warn when the pressure is less than 25psi and vehicles with a recommended tire pressure of 33 will warn when the pressure is less than 27 psi. In 6 years, I've only had mine come on once. There was a nail in the tire and the light came on when it dropped to 26psi.

I use a good quality dial guage to check pressure. There are a lot of cheap gauges out there that don't give anywhere near an accurate reading. Pen style gauges are generally crap in my experience.

 

this time of year when the temps dip mine usually goes off, just need to add some air.

 

Set them all to 35 and let them be.

 

This system actually did it's job for me once also. Right rear flat on the freeway - saw the light before I felt it, got off and lucked into a gas station with a pump (to top off the spare). Light stayed lit until I had the original tire patched and remounted that wheel - then went out after I drove about 10 minutes.

There is also an elaborate "ID registration" thing in the service manual which needs to be done after replacing a transmitter or the BCM. The procedure involves the Consult-II plus filling FL tire to 34lbs, FR to 31lbs, RR to 29lbs and RL to 26lbs and driving 25 mph for a few minutes.

Sheesh.

 

Mine works well. Light only comes on in the winter when the temps drop. Just a reminded to go fill the tires a tad. I use nitrogen....it's more stable and doesn't leak as much due to large particle size.

I keep mine at 33psi and rebuilt the TPMS sensors a year ago when I got new tires. I can go months with a 1 psi drop. Only time I have to fill os when temps drop from 60's to freezing. The light reminds me to do my "seasonal adjustment"

I like the TPMS system.

 

I like the desert system. Rarely gets cold enough to affect the TPMS system.

 

TPMS has been regulated for all cars built 2006 and onward. My set of winter tires doesn't have TPMS sensors - no way I'm spending an additional $200+ on those - so my light stays on all winter. But all in all, I actually like the feature. I have never had it come on unnecessarily (other than winter time, of course). That may be related to my obsessive attention monitoring the tires to maintain proper inflation for optimal MPGs, which is pretty poor and the real source of frustration for my G35. That and driving an auto - will never, ever purchase another auto trans again.

 

^ actually your TPMS light wont come on until about 30-45 minutes of continous driving if your wheels dont have the sensors. The light resets when you turn off the car. I dont have sensors in my winter wheels and rarely get the light while city driving.
