ESIM error code

Hey All, I'm looking for some assistance with this. My check engine light came on yesterday and is throwing code# P0456. It is saying to replace the Emission System Integrity Monitor (ESIM).

I have been looking around on the internet and have been trying to find the location of this thing. It is an inexpensive part and I am fairly handy so I'd like to try to replace it myself.

Has anyone experienced this issue? And or does anyone have any insight of whether this is a easy to replace part and where the heck is it located?

Any help would be greatly appreciated.

Thank you

P0456 is a code for a small evaporative emissions leak. Could be as simple as a loose gas cap. Tighten it, drive around for a few days and see if CEL goes away. If not, replace cap for cheap insurance. If that doesn't fix it, you could have a leak anywhere.

Thanks dude.. I will give that a try.
