So my tire pressure monitor ligth has just started doing this for a while....

randomly starts blinking for a bit, burns steady for a bit, then goes off compleatly.

Then the cycle starts over.

I did a quick search, came up with nothing. All my tires are at the propper pressure. Any idea? bad sensor??

sounds like something funny is going on with one of the sensors. the only reason i know of that it should blink is if your over the programmed over pressure level of 65 psi and it should come on solid at 20psi i believe or if there is a 3% difference in pressure between the tires. you know your pressure is good so i would take it in since your under warranty and have the sensors checked out

probably a bad sensor. are you driving through areas with significant elevation changes?

26-27 psi light comes on, I air the KM2's to 50 on the road, and air down to 13-15psi offroad. Ive never seen a diffence is pressure between tires set off tpms. On the my truck our on Jagaurs at work, although people claim it does, I just have even seen it happen. But I would go get it checked, you can put the system in a programming mode and maybe its in it, or that the systems way to alert you that you need have the system checked....Its amazing we've gone decades without this system, and have become tethered to it now. I do like it as its saved me twice being stuck out on the road with a flat somewhere

I think they go off higher than 20 psi. I think it is actually somewhere around 30psi. If you have the tires closer to 30 psi, they will sometimes trigger the light when the tires/vehicle are cold. As the tires warm up, the pressure increases as heat builds. This turns the light back off. Try bumping the pressure closer to 35psi to see if that fixes it.

All 4 tires are exactly at 36 PSI. I haven't driven over any elevation changes, and its been a constant 90 something degrees here every day this week lol.

Guess I gotta WASTE an entire day and go to the stealership :censor:

Ok so does anyone actually know anything about these sensors? Where are they located? How can I check them or trouble shoot them? I really do not wanna have to to go to the dealer ship and lose a day of work.

They are inside the rim at the other end of the valve stem.

yea not really anything to check man, try to reset the system and see if that does anything. if not, take it into the dealership one way or another. sounds like you've got a dud sensor if i had to guess. that's really the only thing i've ever heard going wrong with them (other than people, myself included, forgetting to check the PSI as temps fall around winter time and the light coming on because the pressure dropped too low)

they do have diagnostic tools that you can buy that can reprogram them and stuff and tell you whats wrong with one but they are between $150.00 and $200.00. just take it in to the dealer

Mine was doing this and then eventually it started staying on constantly. It turns out that a battery was going bad. When it finally got cold it stayed on constantly so I took it in a couple times. Finally I got 3 sensors replaced under warranty and I paid for the fourth.

The batteries are not replaceable and the entire sensor needs to be replaced. What a bunch of crap. I want to know who came up with that brilliant idea.

If it hadn't been for warranty I would have just removed the LED.

most likely because they want the piece to be completely sealed so there's no way that a battery cover and/or battery could come out and bounce around inside the tire while driving. keep in mind these same (or at least fundamentally the same) sensors are used in everything from the versa all the way up to the 193mph GTR (and even higher speed cars from other manufacturers). that's what i would think, tho it is a good way for the company to make money lol

I just had the blinking TPMS happen to me last week. I just put on new TG and everything was running smoothly, then I drove up to PA on about a 3 hr drive and it randomly started blinking, went steady, and then went off about 3 times throughout the trip. I took it into the dealer and they said they reset the computer. Overall what they explained was that there were a lot of old error messages from low tire pressure and when I got new tires it just initiated the blinking for some reason. Anyhow, it didn't cost be anything and hasn't gone off since. So yeah I would agree with most people, take it to the dealer and hopefully you don't need to replace any of the sensors and you only had my problem.
