496 SeaCore Bravo III DTS with Axius
So i’ve Read and searched the forums for information on 496 water pressure sensor replacements. I replaced both of mine this weekend, but they will not read and boat goes into guardian mode. Do these need to be reset to be able to read water pressure? They are from a dealer and are suppose to be OEM replacements. Thanks in advance for the help.
 
No, they are plug and play. Did you keep the old ones? Put one back and see if it reads it.

Thanks and yes I kept the old ones. Once I put the old ones back in they read the psi right away. Just thought I’d put new ones in and save the old ones after reading some posts on these forums. Seems odd that these OEM sensors (8M6000623) wouldn’t work?
 
From what I recall, I think I used a different part number:
881879010
Not sure why the ones you received do not work.
 
Looks like this part number cross references to the one I used. Guess I’ll need to contact the place I bought them from.

Turns out the dealer gave me the wrong part number. Never checked the bottom of the actual sensor, but the correct number is 8M6000623.
