hey 6gc,
I have a question for your collective hive mind of wisdom. I'm trying to diagnose an evap emissions code and cant figure out what this wierd black box is behind my fuel tank. Haynes is useless since it doesn't even show it anywhere in the fuel system diagrams. I'm really stumped by this! here are the pics:  its located in the space between the fuel tank and the spare tire well  it has a bunch of what look like solenoids connected to it.  not only that it seems as though the fuel send and return lines are involved as well, but im not sure as i havent dropped the tankanyone know what this is? what it does? and how it can break/influence evap codes? --------------------  |

QUOTE (Smaay @ Nov 5, 2014 - 12:14 AM)  P0446 is the CCV, cannister closed Valve. that is actually in the engine bay. its the VSV that is round with 2 nipples on it at 90 degrees to each other. one goes to the intake between the throttle body and filter. and the other end goes to a hardline. the CCV is mounted just behind the fuel pump where the older charcoal canisters were mounted in the earlier years Smaay, I have this exact code. I have taken some pictures with hope that you can clarify which VSV you are referring to.
