i got a new rear driver side tire because of non repairable damage to the previous one.

its the same tire model, and the PSI is 35~ but the low pressure gauge wont go away, its been there since my flat tire... is it something i need to reset?

or?...

 

Mine goes on and off so im not sure, but I think that they need to be re calibrated

 

Mine has come on a couple times since I got my new wheels and tires. Its just briefly and the tires aren't low. I dont know whats wrong. Anyone have any suggestions?

 

not sure but it doesn't bother me.....

 

do u think if i bring it a dealership theyd take care of it for free since im under warranty still

 

Is it possible that the shop damaged the sensor when they installed the new tire?

 

yeah ive been having this problem too but in reverse, if im on the freeway for more than like 20 mins itl come on but during city driving it doesnt, i dont know whats wrong

 

I don't think the low pressure sensor is really a "low" pressure sensor. To my experience, it senses "high" air pressure as well. My problem with the sensor started after I got a flat. The repair guy checked all my tires and put a little extra air in all tires, which immediately made the sensor go off. I would only drive five to ten minutes on the freeway and there it was. I figured the air inside the tire is getting warm and expands, setting off the sensor, since the flat was fixed well and no air was leaking out. Of course, I used a guage and measured cold tires. So, I emptied some air outfrom all the tires, little by little until it would last about forty minutes on the freeway without lighting up.
I just got new tires, too, which are wider on the stock rims. The sensor still comes on after about an hour of freeway driving only. I figured the sensor is not used to the new tires and am ignoring it for now.
IMO, the air pressure sensor is useless and only makes you nervous. I'm thinking about having the dealer disconnect it. I just walk around the car every time I'm putting gas in it, which is every 4-5 days, and as I enjoy its beauty, I take a look at the tires to make sure they look like they have the same amount of air. You could also measure cold tires once a week when you're shining the rims.

 

If you have aftermarket wheels then the TPMS will go off in alert mode after 40 miles of driving. That because it does not see the sensor on your new wheels. If you are riding on stock and it's happening after a flat or a tire has been changed then take it back to the dealership for them to reset the TPMS. Your TPMS may need recalibration or at least check for proper setting.

 

possibe damage to sensor ?? possible to much air pressure?? possible sensor needs to be re-set??

 

MIne always on.

 

Did you check to see if the shop mounted the tire with the sensor back in place? You can check the valve stem to determine this. The sensors are a metal sleeve with a nut that sits into the wheel. If it's a regular rubber/plastic valve stem then they didn't put yours back on.

I once believed this as well but have since changed my mind.

My light came on with the 10 second audible alert. I checked my pressure and it was 28psi. I filled it to 35psi, the light went off, and I was on my merry way. Low and behold a couple of weeks later the weather got colder again and I had the same alert. This happened again, twice. In all instances the alert sounded when I had made it a few blocks after leaving my house. Each time I measured the tire was 28psi. Therefore I believe the sensors work great and mine seem to be very consistent.

Also note that there was no visual difference in the tire when it had only 28psi. In other words just walking around the car and looking at the tires will only help if your tire is FLAT. Now if you take that time to measure your pressures that would be more than sufficient if the sensors bother you that much.

My (!) light does come on after about 40 minutes of highway driving. It is pretty consistent this way too because on the drive home it often lights up when I am near the same location. I have learned to accept this as a norm though since many people state the same.

 

Sometime my flat tire sensor on during a cold morning (cold spot within the tube) but after few mins with 20+mph, it would automatic turned off. If your sensor is still on, there is a nail or something punch into your tire but you dont see it unless you rotate the tires around or lift it up. I got it couple times, darn these nails. I have to move my car back and forth so I could see the whole tires...all of four of them since the sensor didnt tell me which tire was flat!! Check for a little nail...that is the main caused to trigger the sensor..at least for my case!
