Lr Tire Pressure
I keep getting msg in DIC that LR tire pressure is low. I have put air in it checked it with two air guages says 35 and DIC rpts. After putting air in I reset the DIC. Still coming up 25 on DIC. Do the sensors in the tires go bad often ? How much do they run ?

If a reprogram doesn't work, then it may be a bad sensor. Sensors are about $85 each and they normally have a life expectancy of between 5 and 8 years.

The sensors are battery powered and are expected to last 5 to 7 years on average. They were designed to be non-serviceable as they are a sealed unit. There have been some reports of owners having luck replacing the battery in them. A search should reveal at least a couple of threads on this procedure. I have yet to read about the long term reliability after a battery change. There are two different sensors, one type for '97-'00 and one type for '01-'04. They are not interchangeable as the receiver is different so be careful if you go the ebay route. You can try retraining as posted in the procedure above and it that doesn't do it, you might need to replace it. I'd recommend one of the forum dealers like Fichtner's or Fred Beans as they sell parts to forum members at a discount.

I've never had this problem, but incidentally, my LR tire has been consistenly losing air much faster than the rest of the tires, and a buddy of mine with a C5 has the same problem. Has anyone else seen this?

Good advice - especially in cooler weather, the o-rings might harden enough to lose their seal. There is a torque value, but I don't have the manual with me right now. It's not much, so I would just make sure the nut is tight.

For the '97-'00s it's approx. 106 to 109 inch pounds. I was checking mine a few weeks ago and found a couple that needed a little snugging up after my wheel change.
Just remember: the nuts are aluminum so try to get the torque as close as you can without overtightening. HTH

Those sensors can drive you crazy i have a compressor in the garage and i always check the tires on the vette and the gage will read 30psi on all the tires but the dic will read differently one might read 30 another 29 so i don't think the sensors are perfect i usually go by my gage..........Charlene

If you have reprogrammed your tire pressure sensors, you will have already eliminated this possible problem. If you haven't reprogrammed, the following situation is distinctly possible -- in fact, it happened to me. If the sensors have been removed from the wheels during a tire or wheel change, they could have been replaced on different wheels. If so, and they were not reprogrammed thereafter, everything would appear to be working correctly. But when the DIC reports a low tire, the actual low tire is a different one than specified on the DIC. Have you checked the pressure in ALL the tires to see if any one of them is low? Of course the real fix here is just to reprogram the sensors.

I am glad this thread popped up because I was going to ask sooner or later. This CF is awesome.

tire pre sure value stem problem
Originally Posted by Wisdom
As a matter of fact - I took my car into a local Clear Lake chevy dealership in October for warranty work. Ever since the car came back I seemed to lose maybe 1.25 lbs per day from one of the rear tires. The dealership had no business working in the tire area, so it had to be something else. So every chance I had I was on the ground looking at the tire for the suspect nail. Yesterday I finally had my tires replaced with Nitto 555's from Discount Tire. There was no nail in my problem tire. Today my rear Nitto's pressure was lower than yesterday's - so I finally woke up and used a 12mm wrench to tighten the valve stem. My problem tire's valve stem (aka pressure sensor) was looser than it should have been. I suspect that tomorrow morning that tire will have the same pressure as the others. I don't know how the sensor would have gotten loose all of a sudden in conjunction with the dealership visit. But you may want to check the valve stem to make sure it's tightened. There's a rubber o-ring or some sort of seal on them and I don't know if there's a torque value. But you should be able to tell if your problem one is looser than a good one.
