"Service tire press mon sys" message ques
My 1997 coupe has been throwing the "service tire monitering sys" warning on my dic intermittently. I flipped over to look at the pressures on the left rear it read "LR xxx" but read pressures in all other positions. It'll do this about once every 3 days now. Does that mean the sensor went out (is going out) on me? Is there a battery in there that could go bad, or is it easier to just get a new one. Suggestions?? Thanks guys

I got that same message when I took the car ( 99 ) out of storage. It showed low air so I checked and filled up all the tires. On the drive back home I got that message. So, you think we need a new sensor? I run with run flats so those sensors have to work.

Chances are that yes, the sensor is going bad. First try and retrain the sensors and see if the message reappears. If it does, you might want to replace the sensor. Unfortunately, they are the more expensive sensors to buy.

Having XXX on one wheel means that the receiver is working fine so you just have a failure of the battery on the sensor on that wheel. The battery life is 7 years or so depending on use so its done quite well to go 11 years.
You may find that all your sensors slowly die over the next few months/year. You may want to bite the bullet and replace them all while you're at it.
Unfortunately, you have a 97 so you have the old type sensors which are more expensive. that may affect your decision. Make sure you get the correct sensor as they work at a different frequency to the 2000+ sensor.
One Forum member (Corvette Don) replaces batteries but its not an easy job. The battery is potted into the sensor housing. Given thet the tire needs to come off I just paid up for a new one when I had a problem with one of mine.

I agree with DeeGee....
battery has died in one sensor.

I would advise you replace them all at the same time. Eventually you are going to have to anyway, and you may as well get it done. This way, you know they are all new and won't have to worry about them for 10 more years.
