Hi all car sifus. What's the purpose of this hose as pointed with yellow arrows on picture? Just now i accidentally broke this tube on my Kelisa but the car still running normally. Is it ok to leave it unconnected?

That is definitely not PCV valve hose. It does not come out from valve cover and is too small. PCV hose usually links to the intake hose after the air filter before throttle body.



This tiny hose attaches after throttle body. It could be a throttle body heater hose or vacuum advance hose. But cannot be certain.

Yes, it's after the throttle body. Can feel air sucking in and if I cover it the engine will shut off. On the other end where it goes to the block cover, there's little smoke coming out from it.
