I am working on my neighbors 04 s60 non turbo.it is running lean and thecrankcase has a bad vacuum leak internaly.there is vacuum valve bolted to the intake,behind the p/s pump.i cant find any info on this electrical vacuum valve. Any ideas?

 

Can u described further how u came about this diagnosis. Was there a DTC. I'm just curious so if happens to my car, I'd be prepared to deal w/ it. I still have to see that valve u r referring to. Can u post a pic
