Hello Gary, thanks for reaching out. It is rare, but I have heard of the O-rings giving out and causing the sensors to leak. If this is the case with your sensors, then yes, the Replacement O-Rings # TST84FR are exactly what you need to fix the issue.
Was the bad sensor on your trailer? Or do you use them on your truck?
