P2420 not sure what to do now
Hey everyone, I’ve had this code come up on my Yaris for awhile now(ever since I put some engine cleaner in the fuel) and I’m not sure what to do at this point. My understanding is that this code alludes to the evap canister valve being open. I tried a new gas cap first but ultimately had to get a new evap canister. Way to much money later and the code is still coming up. I’m not sure what else could be wrong at this point as the connections seems right and I don’t see anything screwy with any of the lines leading to and from the canister. Anyone have an idea what might be the persisting issue?
Thanks in advance.
