C0210 Rear Speed Sensor RH circuit

My 2005 started getting this code when its wet out, once it dries up the lights will go out. I have checked and confirmed that there are no other codes with Techstream. I have seen where some have had this issue due to bad wheel bearing and some due to wiring. Do you think the cause would more likely be wiring since it only happens when wet. Thanks in advance for any advice as crawling around under the truck isn't as easy as it use to be!

 

Did you ever figure out this issue? I'm getting CO215, Rear Speed Sensor LH Circuit.
Thanks

 

It ended up being the connector where the rear sensors connect to the main wire harness. After the frame replacement a pin was loose, i pushed it back in and added dielectric grease and have not had an issue since.
