I have never gotten a "high pressure" warning before on two of my tires. Does the sensors need to be replaced? Any help will be greatly appreciated.

test the pressure with a hand help pressure gage. Normally a high pressure warning occurs above 45 psi.. you should be running your tires around 30 psi.

I went and check the pressure on all the tires. They were over 30 so I put the proper pressure in each one and then reset the sensors. I will drive the car tomorrow to check to see if I get the warning.


Thanks,

It's possible you may have left some info out of your first post, or at least worded something wrong.
Did you take your car somewhere they would have added air to the tires? Like an oil change place, etc? I've found recently that many "experts" at tire stores add air up to the max on the sidewall instead of recommended pressure.

It might be the "experts" can read numbers, but not english, but I really can't explain a mistake that could become a safety issue

So are you still getting the warning? also what did you mean by resetting the sensors? ( do you mean relearning them ) you don't have to do that, recognizing their RF radio frequency is all that relearning their position does, it has nothing to do with how the sensors read the pressure.
when you checked the pressure manually, what was the temp you found?

The requirement to be an expert these days is not much...that bar sets pretty low

I took my vehicle to the dealership last month and had them put nitrogen in the tires, but I have not driven the vehicle since until yesterday. I did a check on the tire pressure last night and it was high. So I removed some of the nitrogen and got the tires to 32psi. I also did a relearning on the sensors. I will take the vehicle for a ride later to see if I get the warning again.

Thanks for all the replys.

Yes, Relearning sorry.

I asked if you were still getting the warning and you said " YES" ???.
I also asked what the pressure was and you keep ignoring that.

Who told you to put nitrogen in your tires? a waste of time and money
You went to the dealer they sold you on nitrogen.. how much did they charge?

Do you know that regular compressor air is 82 % nitrogen and its free.

Do you know not to ever go the that dealership again? They are not professional if they are overinflating tires.

I HAD ONE OF THOSE EXPERTS PUT 70 LBS IN MY SUBURBAN'S TIRES

Its very hard to trust anyone. even some seasoned mechanics refuse to use a torque wrench, in their mind they know what the torque should be by hand. We did a dealership test on this and found most mechanics were 5 to 15 % higher than the torque spec ( over torgue ) less than 1 % were lower than spec. using the wrong torque spec , especially on an aluminum alloy engine can be a very bad practice. I use a torque wrench on everything. the wheel studs on a C5 require 100 ft. lbs. of torque to properly stretch the major pitch diameter with the minor pitch diameter. anything below that can become lose, anything above that can cause stud failure.

Did not keep ignoring question I had 40 psi in the tires. I had nitrogen in my 95 pacecar tires for 5 years and it never changed. I went to my local dealer Sands Chevy in Surprise Arizona and they charged $20.00. Took the vehicle for a ride and no warning. Thanks for the help.

Oh no, not this again

Why did you have 40psi? THAT'S WAY TOO HIGH. 40psi can easily go up to 45+psi in Arizona heat, which would set off the high pressure warning.
