Why? Did you change the throttle body with a different one?

 

No. Standard maintenance. Removed it from the car, sprayed it down and cleaned all of the build up out.

Many consider this an every 75k mile service to keep the car running well.

 

What is your maintenance history? Your PCV history? Why would it need to be re-calibrated again if the TPS, built into the TB assembly, has not changed? There are still running adaptations and your baseline hardware remains the same.

Your case may be different. Mine wasn't bad at 167k miles and I was able to clean it with some brake cleaner and wiping off the build-up.

 

I think what I wrote before wasn't clear. What I was saying in my first sentence was that at some mileage interval throttle body cleaning is still prudent, even if the 3.2 isn't as bad as the turbo in this regard -- not calibration: maybe as you stated nothing is needed.

Regarding your question, original PCV components -- no maintenance performed yet and no symptoms of it needing it yet.

 

Here's a post from someone who did a TB cleaning on a 3.2 (XC60), no calibration-

Cleaned the throttle body

So I cleaned the throttle body. It's not as scary as I thought to be but it takes some effort. I didn't disconnect the battery but I made sure the engine is off and ignition is off. The reason is we don't want the throttle body motor to work against us when we turn the valve inside the...

This is one in-vehicle calibration that I know works with the 5 and 6 cylinders (heard it on my 5) but I'm not sure I've heard anything on the V8s when I've tried it (Denso like the 3.2)-

Electronic Throttle Body Calibration (How To:)

Hey SS I have been meaning to post this for some time but in light of seeing all the problem threads I thought I would share... I usually do an electronic throttle body calibration every 6 months or so. It is super easy and the first time I did it the car was a different machine... Step 1: Turn...
