code p0449 evaporative emission canister

where is the evaporative emission vent solenoid and canister located on the 05 uplander?

There seems to be a difference if this is a short wheel base or long wheel base. For the short wheel base the Evaporative Emission Canister is located on the side of the fuel tank. For the long wheel base the Evaporative Emission Canister is located on the fuel tank. For the Emission Vent Solenoid if its short or long wheel base this is located on the tank. If you have further questions, please feel free to contact me directly. Thank you.

Don't forget to check for a bad fuse, or relay to the purge solenoid!
