Squeel... Check Engine Light Blink!

I just turned a right and I start accelerating a little harder than usual and I get a slight squeel from the right side of the engine bay it sounded like and the CEL (which has been on for about a month) starts blinking and then spots after about 20 seconds. Any ideas what could have caused this? The serpentine belt was replaced about 2,000 miles ago if that helps. Thanks.

Really need the code here, the squeal is tough without hearing it.

I'll try and get a code ASAP and the squeel was very soft and short lived for that time. Everything seemed to work fine after it happened too.
