P2418 Code

1531 Views 2 Replies 3 Participants Last post by  NCEdwardM
MY 2015 Volt is throwing a P2418 code. I replaced the entire evap system assembly (see attached picture), but the code remains. I can clear the code, but it comes back at next start up. Does anyone have any experience with this?

I have a 2011 with the same issue. It's throwing a P2400 and P2418 code. I've replaced both solenoids, one under the hood, and one in the EVAP assembly, the leak detection pump, the evap canister, and the gas cap. I've also cut away the harness sheathing to look for corrosion. Can't keep the codes from coming back after a power cycle.

Did you solve this?
