Drake, I agree with Ray, The message you’re seeing does not refer to the RTS that has been absent for years- it’s an issue with an internal sensor. I have seen intermittent warnings relating to internal sensors on VFX units that have self-resolved with a reboot, but if the warning is persistent then you’ll likely need to open the unit up and replace the sensor.
