2006 xc90 2.5T L5 150,000mi.
This last winter, when it got below 0 F. I got a service engine lite. The garage said it was a sticky throttle body. I exercised it and it went away, until the next cold snap. So, now it is august and I am thinking now would be a good time to clean the throttle body. I watched a you tube demonstration.

It seems like an involved and challenging weekend job, but probably do-able. No special tools, and some cramped working conditions.

Is there any advice out there?. Can I clean it on the engine or do I need to remove it to do a good job?

Is there any reason I should replace it? I would like to get another 150,000 mi out of it.

Any advice or thoughts would be welcome.

 

A quick google search revealed this link with a good write up.

I was able to access the four bolts holding the throttle body onto the intake from under the car. It takes a strange combo of socket extensions but it's possible and it beats working blindly under the intake manifold.

So it's not a hard job, just takes some patience because a lot of the work is blind.

I believe some people have cleaned the throttle body without actually removing it from the intake. This could work but you'll definitely get it cleaner by removing it completely.

Good luck!

 

thank you. I will do this next weekend. It sounds challenging but I'm pretty sure I can do it. I have to get this done before it gets below 0 again.
