Hi, am trying locate the above as I suspect it being the source of a severe hunting idle. I have cleaned the throttle body and Ian and checked off vacuum leaks and I have pulled a code for the above but can't find it! The engine is a 1.8 volvo unit with an auto box. I hope this sorts it as the car drives well and only has 56k on it and failed the MOT on emmissions! Any help appreciated!

 

I think.....

 

Thanks hudini, unfortunately that's not where it is on mine, I think that's the turbo location . I think it may be combined in the maf sensor so will give that a try....

 

Was indeed in the maf sensor on case this helps anyone!
