cleaning EGR valve?

My check engine soon light came on last week, and I took it to Autozone to determine what it was. Turns out that the EGR valve needs to be cleaned out. Anyone done this before? Seems as though cleaning it out would be a fairly simple to do, but I have no clue where it's located. Any help is appreciated.

TPAT, I would check the hose that runs from the Air Pump to the air valve. It is located on the passengers side of the car/engine, toward the front of the car and left of the engine (when you are looking from the front of the car backward). The Air Pump is a coffee-can sized black cylinder, and there is a hose which connects it to the valve, about 8 " long and shaped in an "S" preform shape. The hose is not expensive ($7-8), but they tend to deteriorate after a while, leaking and possibly throwing a code. I'm not aware where the EGR valve is located (could not find much info on one on-line), but typically they can't be cleaned and are best replaced. I've had to replace it on our E46's and I know it's a common hose to fail.

the S shaped hose goes between the SAP and the EGR valve which is mounted on the head.
