Fiat Ducato Oil level sensor

[Royalmate]

I have a Fiat Ducato year 2018. I got an error code "P250A-12 - Engine oil level sensor - Short circuit to +V" read whit MES but I can not find any connection to any control module.

My control modules are:
Marelli 9DF CF6/EOBD Diesel Injektion (2.3)
Body computer Marelli (290)
Bosch ABS 9 ESP
TRW AIRBAG MY14
Intrument Panel Marelli
Service Interval Reset

I can't find any parameter that includes "Oil level sensor". Does anyone know where I should look? Could it be that MES has missed this parameter?
I've seen this parameter when I've been looking around mes for other vehicles.

I thank you in advance from Sweden

Maybe check the sensor the old way, looking at the wiring or measuring resistance at the sensor itself, if the sensor is not expensive; just replace.

Thanks for the tip. I cleared the fault codes and they didn't come back for a while. Now they have come back and it seems the error codes come on when I am not using the car. This may be due to the solar panel on the roof. The voltage may become too high when left in the sun. I got this error code at the same time "P0657-17 - Congruence of main relay battery voltage upstream/downstream - Voltage too high". I'll try disconnecting the charge on the starter battery
