Later years were 25psi and 27 psi as set points for turning on the TPMS light depending on what model wheels you ran.


Either way. since they have been on the car for a while, they worked. Blinking light is a system error message. It has nothing ot do with the pressure inside the tire. Im certain the reason it comes and goes is because one of the sensors is nearing the end of it's life and you are getting intermittent readings from it.

With the blinking light, option is to either self run the codes, or take it to a tire shop and let them diagnose it. I'm betting a new sensor is in your future. 5/6 years or so is about when they start to die.

 

FWIW

The TPMS sensors communicate a RF signal of spinning wheels thru an antenna to a receiver to the ECM.
Each TPMS sensor has a non replaceable battery with a lifespan of approximately 5 years.
Each TPMS sensor should be properly programmed to the correct wheel by the Consult lll that the dealers use.
If an independent tire shop cannot do this then you need to visit a dealer and have the sensors properly configured and tested.
You cannot pass inspection in some states with a TPMS indicator on and a dealer cannot legally allow a vehicle to leave their shop with a TPMS indicator on.

If we want to get all technical: the remote keyless entry receiver receives the RF signal and the body control module (BCM) then reads the signal and controls the warning lamp. I'd assume one couldn't even unlock the car remotely if there was a problem with either of those two items.

Most tire shops these days have the proper programming equipment, it's no longer "dealer exclusive." Costco just installed new tires and all new sensors on my wife's Armada and everything reads correctly.

Interesting about the inspection aspect. My summer wheels don't even have sensors so the light is on all the time, dealer or shops have never mentioned it.

 

ive had a lot of different wheels-none have ever had tpms in them. never had the light come on. last time the light came on was when i had my stock rays on lol

 

Man, I have the same issues in my '04 - Same TPS issue (I also tried airing up, etc.) and Airbag light (It resets but comes back, usually when the seat is move a lot). My CD player still works, but my clear coat has blistered and the door panel leather is pealing back.

Tagging this for solutions - but sounds like I need to hit up a tire shop for TPS sensor replacement?

 

Only way to do it is to dismount the tire slightly to replace the sensor. It's inside the rim.

But tire shops can also reset the sensors too now. Not a dealer only thing anymore.

 

UPDATE: 03-28-16
Cold PSI must be at 35lbs. and no more as I found if I use 36 psi cold and drive for over 1.5 hours at highway speeds the tires warm up enough to increase pressure to just over 41 lbs. which sets off the "high" trigger and then turns on TPS light and stays on till I restart the car. If I set cold psi to anything lower then 35 lbs. it sets off the trigger and the TPS light comes on. Note: the light is not blinking... its ON stays on, well till I restart the car then its off. I did not have these issues before the Kuhmo tires.. I suspect these tires have less flexibility regarding psi increase or decrease.

 

I run 50psi and this is not an issue.

What IS an issue is if you have no tpms or one of yours is broken. I am running no tpms right now and mine light comes on after 45 mins too. Then i tried to disable it thru the bcm (with cipher) and it still does it.

 

Well I was thinking of having the reader disabled too... but from what your saying not much luck there!
wow 50 lbs psi ? that is max for my Kuhmo tires... I will religiously keep at 35 psi on the dot cold morning, see how it goes... seems odd that mine are so sensitive now with these kuhmo tires as I never had the issue before.

 

Yeah, luckily 95% of my drives are around 35 mins. Haha

 

Whatever sensors Nissan gave you are incorrect then. Set point should be much lower, 27 or 29 psi IIRC.

Not that 35 psi isn't a bad set point, but if you've upgraded to wider tires, you trypically can run less pressure as there is more surface area contacting the pavement. I've religiously run 32psi in my tires for years and get nice even wear for 70K miles of tread life out of my continentals.
