guys, i have a p0410 on my 1997 960, i tried this mod a32 to a37 and ensured the diode was pointing the correct way, but i have no luck. CEL still comes back in 2 mins. I even tried a32 to b38 and both together.. none of them worked. anyone else here try this on a 960?

Jim, you are correct, i read the code again and its P0410. So, removed the valve and its functional, the air pump to is working. but the steel tubing when pressurized with 45psi air the air went no where. I cleaned the tube which had oil and tried putting air pressure in the hole where the tube was ...

thank you Jim. I am going to try that out.

Jim, do you happen to know what i would need to do with P0401 and no EGR present? I was going to clean out the EGR if it were there. Would i have to look at breather or Airpump as my next item in line? thank you.

using that and my vin YV1KS9609V111217, it seems like its w/o EGR, w/air pump. then what should P0401 mean? how to fix that?

Jim/Bill,

I cant seen any EGR tubes entering the intake manifold. I will look closer near starter. I dont find the rear EGR pipes routing to the other side of the block.

Thank you Bill!

I will take a look at this, I get a better picture in my mind, seems like EGR is below the starter.

Can someone help me? I have a 1997 960, it has check engine light on with P0401 --insufficient EGR flow. I am trying to locate the EGR valve based on this thread here and this link for location, but i dont find the EGR feeling my way with hand or visually. http://www.volvopartswebstore.com/images/pa...
