So I tried fixing them before but I guess no luck with a complete fix as these codes appear again. I got a new gas cap and the evap leak detection that's by the gas tank but I still get this code. And for the P1d73 I found that it could be the grill shutters which was true they were not aligned so I fixed it this code comes up after a few weeks and I am not sure what else to do. I do realize my fan runs whenever it was warmer outside even when my A/c isn't on and I hear it running almost continuously. I hope you guys can help me figure out these issues. Thank you.
