Technical Oil supply solenoid

[Giovannideluigi]

Hi everyone! I just purchased a 2016 500x. What a beautiful car! It had 124,000 miles on it. After driving it around my hometown in Michigan for about 4 weeks I drove it 1,260 miles to Colorado. It didn’t handle the hills very well and when I got to my destination, the cel came on along with a message to change the oil. I did the oil change and the cel came back on. I had the code read and it says oil supply solenoid stuck! Does anyone know, Is this a serious problem? I have to drive it back home to Michigan soon. Thanks

More information the engine is the 2.4 and the code is P1062

Not an engine we have over here but if you search the Jeep/Dodge forums you'll find quite a few references.

Did you put the correct oil when you did the change and is it still at the right oil level in the engine?

The multiair system in the engines we do get in the UK, 1.4 4cyl, and 900cc 2cyl, are critical on oil quality and change interval.
Having only had the vehicle a few weeks, its history is unknown. I'd guess that the previous owner, or his service agent, has not adhered strictly to the correct oil specification, or has extended the change intervals. This has resulted in the valve sticking. Hopefully the valve can be cleaned, if not, it'll need replacing.
Ensure only the correct spec oil is used. With the unknown history, change the oil again, early, to help get any gunge (technical term) out.

Thanks Portland Bill. They used synthetic oil 0W20. Would that be sufficient or does the brand matter?
Should I try an oil additive?

I don't know what oil the 2.4 uses but 0W20 seems to be becoming more common these days, as it helps fuel consumption (and these very thin oils are good enough to still protect the engine).

The user manual should show the oil spec' you need. The brand doesn't matter but there will be an official oil (e.g. Petronas) that will be marketed as meeting "Fiat standard 9.55535-DSX" (or similar) that a particular engine "requires".

The Fiat spec's refer to particular additives or compounds which may or may not be specifically required by the valve/solenoid system.

If an oil has that Fiat spec' conformity listed then it'll be good for your motor.

If an oil doesn't have the Fiat spec' listed then it may or may not have those additives in it.

a) It may have them but just not say so on the packet (so you won't know) but you won't have a problem using it.

b) If it does not have them, then their absence may or may not be a big deal.
Some additives could just be additional detergent etc. to compensate for the extended change interval Fiat quotes for that engine now, which you won't miss if you always change the oil at half the recommended interval anyway, for example. But obviously the additive could also be quite critical for keeping your solenoid clean...

On balance, I would use an oil that conforms, but an oil of the right grade that is changed regularly won't do any harm. Engines can't be that fragile, or there'd be thousands going wrong.
