Where can I find the Purge Valve on my 2009 Kia Rio LX and how does it look?

can't post pictures here,although you can google the part number PV628 for a picture.never seen anyone pull a code and it tells you to replace any part! Its located behind or under the throttle body if you want to replace it. see rockauto.com for best price compared to local rip off parts stores the ROCK is bout 1/2 price of local parts stores. see link below.... https://www.rockauto.com/en/catalog/kia,2009,rio,1.6l+l4,1444128, exhaust+&+emission,vapor+canister+purge+valve+/+solenoid,4936
