I have a fiat 500 2018..Service Engine Light came on P1066
Cylinder 1 oil supply solenoid valve switch off time out of range..
The scanner said there was a second code but nothing showed up.
Light was not flashing but just need advice before I go to get it serviced tomorrow.
Any suggestions would surely be appreciated!!!

Thank you.

Is the valve cover covered in oil and in the spark plug hole? Change the o-ring between the valve cover and Air/oil separator (AOS) box. easy to do. Of course you change the oil and spark plugs at the service intervals listed in the back of your owner's manual? Did someone work on the engine recently? Mileage? What part of the country? Rust belt?

I had that happened to me a couple of times. First time I spent $160 for diagnostic and they couldn’t find anything other than low on oil and needed an oil change.
Second time that happened I just had the oil change and the mechanic noticed that the oil level was low. After the oil change, the code cleared :)
