Prius engine smoke and power loss

My 2012 Toyota Prius hybrid (131987 km) has the check engine light on, reduced power, and smoke during acceleration. I think it's the crankcase ventilation valve. Anyone seen this?

A 2012 Toyota Prius is experiencing engine smoke, reduced power, and a check engine light, potentially due to a faulty crankcase ventilation valve. Similar symptoms, including rough idle and smoke, were resolved by addressing the crankcase ventilation system. It is advised to have the system inspected by a professional to prevent further issues.

I had a similar problem with my Prius, though I don't recall the year. The smoke and check engine light sound familiar. Any unusual idle or emissions changes?

Thanks. Yes, the idle is rougher. Can you share more about your issue? Were the symptoms the same?

Rough idle and smoke were key. It was a defective crankcase ventilation. Get it checked by a workshop to avoid bigger problems.

Thanks for confirming. I'll get the crankcase ventilation system inspected. Repair is about 360€.
