TPS sensor question
I am getting the "Service Tire Monitor" in my DIC. The front passenger side read out has a double "XX" instead of a pressure reading. The present sensors are going on 10 years old. Re-search seems to suggest that they will have a shelf life of 8-10 years on average. I am assuming that the sensors are just getting old and the others will soon be following with failure but I will not be needing tires for several years. I realize there may be other issues at hand, but since the TPS's are this old, seems like a logical place to start. The question is has anyone ever had just the TPS's replaced and could they share the info on what it cost at a GM dealer....and/or a Mom & Pop Type shop. Thanks

Thanks for the info Hokie....we are neighbors as we are in St. Charles. Any idea where you will be taking it for the install ? There's not many independent shops around here that specialize in Corvettes. Elco is a little far.... I know its spose to be one of the premier Corvette places in the Mid-West, but I personally am not sold on their dealership as far as taking care of the Corvettes their customers bring in. Would much whether use a independent shop.

I have only had my Corvette for 2.5 months, so I don't have much personal experience with the best places to go. However, I can tell you that I've heard great things about the Corvette Tech at ELCO and had him do a four wheel alignment last month without issue.
I don't know if I'll get into doing any mods, but another forum member said that CBI is definitely the place to go for that sort of thing and that ELCO will do a good job with routine maintenance.
I hope this helps!

LOL XOH....agreed...but you know as well as I that anytime you take a Corvette in for service of any kind you hope you get it back in the same condition as when it went in. In this case....scratched wheels are not welcomed....LOL.

Just go to Discount tire and have them put new ones on.
There were issues with my car accepting the sensors and my car couldn't read with the tool or by lowering the pressure below a certain PSI. So what they had to do is take the tires off, let all of the air out of the tires, THEN read them with the sensor while they were right next to the car (Front Left, FR, RL, and RR) and then it worked! Apparently the vettes have issues with the sensors for some reason.

Don't let the tire place tell you that they have to remove the tire to replace the sensor....not necessary. The bead can be pushed aside with the tire machine and then the sensor can easily be replaced by reaching in behind the wheel....no tire removal and no re-balancing required. Less chance of damage.

Discount and most other tire dealers do this daily, because all cars have sensors since 2007. They also will reset the car to acknowledge the new sensors at the same time.

I whole hardily agree and I thought this was the case also...but the shop that I am taking it to (and two others) say that they must remove the tire. You know the drill then....when you go into a place requesting they do the job a certain way they immediately look at you with a scowl acting as though you are telling them how to do their job. Regardless, i'm going to just have the one bad (hopefully) sensor replaced and see how they do. Then if/when another goes bad just have all the others done. That shouldn't be too long as they are now all going on 10 years old. My goodness...it always seems that the simplest things always turns out to be a big hassle !!! Thanks all.

I've given up on mine. Since car was stock (so I can't blame it on all the modifications) I had problems with my TPMS setup.
It works about 85% of the time. 15% of the time I'll get the flashing (!) on the dash cluster yet all the units are reading a proper pressure. Then randomly light will go off and back to business as usual. I'm stumped

I agree with your idea of only replacing the one sensor. There is no monetary penalty for doing them one at a time as necessary. I have two sets of wheels for a total of 8 sensors, 4 from 2006 and 4 from 2007....none have had any problems, so it may very well be that you replace the one and then go a couple more years before another one has a problem. The sensors go into sleep mode when the car is not being driven, so even though they are 10 years old, with few miles they might well go much longer. Lithium batteries have a very long shelf life, and with few miles being driven, the shelf life of the battery is almost more important than the usage by the sensor itself.

They asked me if I wanted the rubber stems,I said no I want the stainless ones that are on there already. No problem. I did call my tire guy today he said to bring it down and he would check each wheel with his tool. But after I explained how intermittent is,he said it may be in the computer. I'm not gonna worry about it right now.
