Low tire pressure warning sensor - ZR-1 Net Registry Forums

Rick Gibbons · 01-29-2023

Hi everyone. I'm new to the registry after buying a 91 ZR-1 last May. My fourth Corvette. I bought it from the original owner's family who stated the tires had been replaced October 2021. It had 9650 miles at the time (just about to turn 11k now). When I got it, I noticed a strange sound like a rock rolling around in a can coming from the right front at slow speeds. My local Corvette specialist, helped me determine that it was the tire pressure sensor INSIDE the tire. The tire shop took it off the rim and found hundreds of pieces inside. After a thorough cleaning, it only took about 5 miles driving to see the service LTPWS light come on in the message center. It resets each time I turn the car off but after about the same distance, it comes back on. I found a replacement on ebay correctly coded for the right front. Now I'm wondering, is there maintenance involved with the sensors? Batteries to replace? The replacement sensor looks brand new but I'm not finding a battery compartment. Maybe the better idea is to remove the remaining 3 sensors, ignore the light, or take the bulb out of that location. I would appreciate your technical expertise and opinions.
