Opel Astra G 1.6 8V Fan & Temp Sensor Issues: Dashboard, Radiator Light, Error Codes & Solutions

Hello, I have a problem with Astra of this type that it does not show the temperature on the dashboard at all, hardly the radiator fan works non-stop and the radiator light on the board is lit, I have already replaced two sensors with a black housing and a white one and nothing is the same problem, after connecting to the computer shows the error temperature sensor, but I replaced two new and the same, from what I know there is only one two-pin, please help. And one more question where is the sensor from turning on the fan? Because he's not in the radiator.

Have you checked the condition of your fan controller?

I pulled out this driver, the pins are ok, not covered, I don't see water or dirt in the middle. I have no idea how to check it. I changed from another Astra and the same fans are running, no reaction indicator

I do not know what engine you have, but in both 8 valves after the diagram comes out that it is based on this sensor the engine controller starts the fan (s) and gives an indication on the counter.
I have another car, but unplugging the temperature sensor plug just causes the emergency turning on the fans.
You focused on the sensor, what about the wires to it?
The driver sees the sensor?
Do you have 5V on the sensor plug?

I did not focus only on the sensor, I checked the plug and it is 5v, as I wrote, I even changed this driver and the same, I dismantled the clocks because someone wrote that there may be a path in the clocks burned out and nothing is all right, cable bundles, unplugged cables, weight checked, I still have a computer, I'm sitting for three days on this problem I have no idea what's going on.
