engine water level sensor error

Hello, sometimes there is a light that gives stop and engine water level warning. When I asked the master, there is a sensor in the engine water container, he said it is faulty. I bought a new one and used it for 1 day. Is the room giving the same warning? I disassembled the sensor socket, I use it. There is antifreeze water in the container. this is the piece picture.

check sockets teacher may be oxidized. replace the cover of a tank as well.

Can he do it on the cover?

Could be missing the air on the lids of the teacher.

I think the cables that come to the socket may be broken or check the fuse box that may have blown the fuse box.

There is no water loss in the vehicle. Let me clean the socket wd40 at the weekend. Let's see what happens.

clean the socket with contact spray, not wd40.

I cleaned and installed the old sensor beautifully and it works fine now
