We have a 96 Corvette that has the ltpws. We had new tires installed at a reputable tire service center. Prior to having new tires put on we had no problems with the ltpws, 3 miles down the road the light came on on the service center, the tire center said to drive it for awhile and let the sensor reset. Did not help. I had the car checked out at a very reputable Chevrolet dealer and the sensor is bad, there is a scratch on the sensor and they said it could have happened during installation of the tires. They did not come right out and say it was damaged when the tires were installed, but they did say the sensors are very dependable and very seldom go bad.does anyone have any suggestions as to why it happened after tires were installed or is it just a strange coincidence that the sensor chose then to go bad.The only sensor that is bad is the right rear Thanks in advance

 

I just went through this a few weeks ago....I bought my wheels off of a '96 and I had to have the sensors removed and return them to the guy. The sensor is just a plastic box held in place with a glorified hose clamp. The tire shop would not even touch the car until I agreed that they would not be responsible if anything was to happen to the sensor. They usually will not even work on rims with the GM sensor. The problem is that they will loosen up and move sometimes so when they take the tire off the rim the machine will crack the sensor. If yours is scratched this is probably what happened....but good luck getting a penny out of them. They are not cheap either.

I have had the same problem. The person mounting my tires (despite my repeated warnings) broke a sensor. They replaced it right away, however, it took a day to get the parts. The system will NOT reset after driving awhile, they simply don't know how it works. I am assuming that they did have proper tire pressure, in which case if could go off after a while with the tire pressure increasing due to heat. Anyway, I wish you luck dealing with the shop - if it is a reputable place and you explain the situation, I think you will have good luck getting reimbursed. They will cetainly remember your car!

Chances are it was damage during the tire change. But the scratch could have happened at some other time during a tire change. The sensor could have decided to go south for no reason. But I doubt it. I see you only have one post here so far. With time you will find many post on here about these sensor and how they are broken during tire changes. Some times the band that holds the sensor breaks. I've seen this happen during a dyno run. The rear tire bounced around so bad we though the wheel was coming off. The owner was very lucky it did not damage any rear suspension parts.

I don't use mine. I removed the LTWS bulb in the DIC and I also don't ahve the sensors installed. I can tell when my tires are low to within five-ten pounds. I don't need a sensor to tell me that. Besides I check tire pressure once a week. Without getting into details and possibly insulting some one, I'll just say the system does nothing for me but may help for some. The sensor are not produced anymore and cost $100+ each. They are sometimes hard to find. I wish you luck trying to get the store to pay for it. I would go back and be nice about at first to see if they will repair it. Go up as far as you need such as a district manager if it happens to be a chain store.
