Question Check Engine Light???

Before I got an oil change, my "check engine" light turned on. I got my oil changed. The light is still on. I got my friend to run the codes and they came out to be P1682 and P0449 (That code was on there twice.)

I did a little research and these are the results I found:

P1682 - Low Cat Efficiency

P0449 - Electrical or Emission Canister Solenoid Emission Valve

If anyone has any suggestions or I am WAY off please tell me. I just want the light to go away (I reset it and both P0449's stay, the P1682 went away.)


Thank you!
