CEL after alignment

[Slipstream]

So I took my awd to the nearest chain (Les Schwab) shop to get an alignment. No big deal, I turn off the car, hand over the keys, wait about 30 minutes they give me back my keys. I get in, and now the CEL is on. I don't know what code it is, but can you guys think of anything they might have done during the alignment that would make it throw a CEL? It's never! given me a cel before...I'm currently have the battery disconnected in an attempt to clear it...any thoughts are more than welcome.

My only guess would be that while under the car they knocked a sensor wire loose, probably the oil pressure one as it is sometimes easy to knock off. Does your oil pressure gauge read correctly? If the CEL comes back on jack it up and look under for a loose sensor or something. Or just take it to autozone and have them scan the code. (free)

The first thing you should do when you get a CEL but nothing seems wrong is go to autozone. Seriously, if they can tell you, why would you try to figure it out for yourself?
