got stuck in a foot of water and towed out. Had multiple codes, a few days later it dried out and codes went away. 4 weeks later scanned and found code 68.33. brake lights work and no abs light on in dash. what could it be?

 

Are the abs light or VSS lights turning on while driving?

I'd clear the code and scan occasionally to see if the 68-33 returns. It could be caused from remaining flood water that didn't evaporate causing an electrical issue and might go away.
