I bought my car under 90 days ago from a Honda dealer (who knew NOTHING about Volvos) but I got a good price. I now LOVE it. However, my check engine light came on (P2112 is the generic code - my boyfriend has the diagnositc tool at work but the codes for European cars aren't fully unlocked) and I'm seeing there was a recall on the throttle in 2006 (although some sites show my 2002 was included and others say it's not). It's not stalling but it's very sluggish ("limp home mode"??) and I don't like having lights on when the main reason for the car is to take my kids places. Taking it back to the Honda dealership seems pointless. I'm seeing prices of $900 back in 2005/2006 to fix. I've read on other sites that Volvo's proceedure is/was to clean it a couple of times before looking to replace the part if it is covered by the recall and that the warranty on that part was increased to 10 years/200,000 miles. Where can I find a diagram of the throttle? What is the best thing to use to clean it? Would cleaning it ourselves void this extended warranty if it is indeed covered? Thanks for all help!!!

Some 2002 models were covered under the extended warranty. Need to have it checked at a Dealer to find out if yours is covered.
I wouldn't start messing with this system before having a Volvo shop look at this, you can create more problems and will end up there anyway.
While you arte at it, have all the software in the vehicle updated.

The ETM recall was associated with a different throttle body than the Bosch that is on your car. The only 2002 V70s that had the problematic type of TB were the carbureted models, not your Turbo. The problem could still be ETM but not near as likely as in the prior years with the different part. It could also be the Mass Air Flow (MAF) sensor which is pretty accessible and easy to clean -- assuming it isn't already beyond that and needs replacing. The other thing that can cause a fuel error and even put you into “Limp Home” mode is a clogged fuel filter. You won’t fix that by dumping cleaner into the tank either – you’ll need to get it replaced.
Of course the real answer is not to just guess but to get the actual Volvo codes. You can probably pay a shop to pull them for you and you’ll also get all of the other codes your car is throwing off and might need fixing as well.
