I have a problem with my Opel Vectra C 1.8 122km, there is a situation when the car with key indicator lights up on a warm engine, the temperature indicator drops to zero and the full-range windmills turn on ... the situation lasts a few minutes, after a few engine off the problem goes on....

Somewhere power or communication is lost. It is necessary to view the actual parameters when the fault occurred.

And what specific parameters, because I would bet on the need to check the temperature reading at the time of the fault and compare it with the indication on the dashboard, maybe the sensor gives a signal that the temperature has exceeded the critical level ...... yesterday I managed to suck up during the event and connect to the computer, the error as I wrote above the temperature sensor after deleting the car immediately returned to the state before the fault, but we did not look at other parameters.

You also checked the cables from the controller to the sensor? You may have a broken wire, quite visible, or hidden in insulation. The power line splits - one wire from the controller powers several other sensors, how are these wires connected, and where?

I once checked the harness, unless there is something on the principle of a torn cord that sometimes makes itself felt.

It happens This applies to lanos, but the first example is universal, while the second - according to the scheme until 2005, the power line separates - one wire from the controller supplies several other sensors, how are these wires connected, and where? In lani, bad for years after plaques, cubes, etc ... One error, or rather a break for this particular sensor, no sensor, removing the plug, break and short circuit, for me turns on the fans for max. Just in case, without knowing the engine temperature, the computer starts the fans ... You have a different car, engine, driver, and certainly a different error that you did not specify. Diagnostics on the computer would show what temperature the controller sees, and if the meter uses this sensor I do not know, I have two sensors. Maybe give me the error number?

Thanks for the help. The next time I get this error, I will plug into the computer and read the engine temperature and compare it with the one on the indicator. and knocks what I look carefully at the beam. Added after 3 [minutes]: The error that pops up for me is: continuous temperature sensor, unfortunately I don't remember the error code

unfortunately the problem returned again, the engine temperature and the one indicated on the sensor is the same, checked on the computer ... besides the sensor plug was replaced and it did not help.

I have a problem with my Opel Vectra C 1.8 122km, there is a situation when the "car with key" indicator lights up on a warm engine, the temperature indicator drops to zero and the full-range windmills turn on ... the situation lasts a few minutes, after a few engine off the problem goes on. During this time, the engine temperature sensor error goes off continuously.
The problem is that the sensors were undercoated 3 and I currently have the original gm, we didn't suspect the engine driver from the electrician and the second one was planted and the problem remained.
Has anyone had similar symptoms?

Thanks for the help. The next time I get this error, I will plug into the computer and read the engine temperature and compare it with the one on the indicator. and knocks what I look carefully at the beam.

Topic summary

The discussion revolves around an issue with an Opel Vectra C 1.8 122km, where the "car with key" indicator activates, the temperature gauge drops to zero, and the cooling fans engage unexpectedly when the engine is warm. The user has replaced the temperature sensor multiple times, including with an original GM part, but the problem persists. Responses suggest checking the wiring and connections between the engine controller and the sensor, as well as monitoring the actual temperature readings during the fault occurrence. The user plans to conduct further diagnostics to compare sensor readings with dashboard indicators and investigate the wiring harness for potential faults.
