First, without meaning to be a ****, I would like to say a few things to help keep you from spending your hard-earned cash that you probably cannot afford to throw away.
1. Your vehicle is equipped with an electronically controlled EGR Solenoid Valve. Failure of these valves are EXTREMELY RARE (Although many parts outlets sell thousands of them based on their "FREE" diagnostics).
2. If you do not know where the EGR
valve is, then you could not possibly have tested it properly. If you have not tested it, then you cannot possibly know for certain that your vehicle needs an EGR Valve to fix whatever
problem you are attempting to repair.
3.
MOST EGR system failure codes are NOT caused by the EGR Valve itself. The most likely cause of an EGR code is clogged EGR ports (Which can be fixed with a gasket, a little elbow grease, and a can of carb cleaner). EGR control circuits
i.e. wires, connectors, etc. run a close second in the code-causing category.

Now that I have done my preaching (and hopefully, helped to keep you from wasting your money), the answer to your question is that the EGR Solenoid Valve is located on the right front of your engine. (See picture)
