XC40 Check Engine Light Air Valve Suspected

Hey, I'm getting a check engine light on my 2014 Volvo XC40 gasoline. Mileage is around 143858 km. I've noticed that the check engine light comes on, and I'm suspecting it's an air valve issue. I've checked the air intake and throttle body, but everything seems fine. Could it be related to manifold pressure or vacuum hoses? Any ideas?

A 2014 Volvo XC40 is experiencing a check engine light, suspected to be related to an air valve issue. The initial checks on the air intake and throttle body showed no problems. A suggestion was made to inspect the hose connection from the pump to the valve, as a similar issue was resolved by replacing a loose or defective hose. The owner plans to have this specific hose checked at a workshop.

I had a similar problem with my XC40, though I have a different engine. Have you checked the hose connection from the pump to the valve? That was my issue.

Interesting! You mean the small hose running near the intake? Was it visibly cracked or something?

Yeah, that's the one. Mine wasn't cracked, but it was loose and seemed defective. I just got it changed in the workshop, it's a pretty common issue they said.

Thanks a bunch! I'll take it to the shop and have them check that hose specifically. They said it was the hose connection from the pump to the valve. Cost me 175€, not too bad. Appreciate the help!
