RHP - thanks for the directions. That will help. Any idea which extractor works on the pins I've highlighted? I've tried the dual pointy pin extractor tip of varying sizes and the single rectangular tip. The cylindrical ones don't seem right.

The next leg of the journey... InkedHarness Connector_LI.jpg I've managed to remove ECM and TCM and the harness connector to the ECM receiver. I identified the wires coming from the throttle body harness and have taped each for future ease of location. However, with my trusty set of pin extractors I...

Thanks, Abscate.

Nice crew to have around. I know I appreciate the help.

R stands for Refined, it is a performance trim level not a different car. After a quick review of specs, it appears the throttle body across the Volvo L5 spectrum is identical, requiring, I would imagine (Forgive my ignorance RHP) the same harness. Have I deduced this properly? Should have done a l...

Update. Took a few days, but I thoroughly cleaned the throttle body. Sad to say, to no avail. Still starting fine and then following shut down and restart, throws P2111 code and jumps into limp mode. So, I guess next stop is harness replacement. RickHaleParker, I'm concerned about fitment regarding ...

As an architect, I don't benefit from your experience. I think I'll try the replacement, though, despite my reticence. I've been shade-treeing on Volvos for a few years and am gaining a little confidence over time. Thanks for your direction.

I think there's one included in the harness kit RickHaleParker referenced in the post above for $40 total. XC70Rider, was the install of the new harness at the ECM a relatively straight forward task?

I may give the new harness you recommended above a try. Thanks, again.

Thanks, RHP for the info. Is this as scary a repair as it sounds in the description? I've never spent any repair time with the ECM before.

Thanks, XC70Rider and EngineeringBloke. Both posts have been very helpful. I did go ahead and clean the unit in the pic. I haven't reinstalled yet, but it came pretty clean... amazingly. I'll pop a new gasket on there and hook her back up this week. I'll follow up with hopefully an all is well post....
