Expedition reduced power and smoke

Hi, I have a 2017 Ford Expedition with a gasoline engine. Recently, the check engine light came on, and I've noticed reduced engine power and some smoke when accelerating. The car has only 25424 km on it. Could this be a serious issue? Any ideas what I should check?

A 2017 Ford Expedition experienced reduced engine power and smoke during acceleration, accompanied by a check engine light. The issue was suspected to be related to a crankcase ventilation valve malfunction, which can cause emissions problems. It was advised to have the vehicle checked by a professional, leading to the diagnosis and repair of a defective crankcase ventilation valve.

Did this summary help you solve your problem?

I had a similar issue with my Expedition. The symptoms sound a lot like a crankcase ventilation valve malfunction. A leak in the crankcase ventilation can cause all sorts of problems, including emissions issues. Has the car been regularly maintained?

Thanks for the quick reply. Regular maintenance has been performed, yes. Where exactly is the crankcase ventilation valve located, and is it something I could check myself?

While you might be able to locate it, diagnosing the problem definitively often requires specialized tools. Given the symptoms, especially the smoke, it's best to take it to a workshop. They can check the crankcase ventilation system and confirm if it's defective.

Okay, I understand. I'll take it to a trusted shop. They diagnosed a defective crankcase ventilation valve, and the repair cost was 360€. Thanks for the help!
