Hey all. Finishing a valve cover gasket, power steering pump etc. replacement on my 07 XC90 V8 Sport 138K and going along and replacing anything that may go bad in the future that's buried under the manifolds so I don't have to pull it apart again and I can't figure out what the two sensors are that stick out of the passenger side of both valve covers (four sensors total). Anyone have an idea?

 

Just answered my own question...They are the variable valve timing solenoids...
