I was troubleshooting a P0441 issue on my 2003 LX470. Throwing the code, plus gas vapor smells from the back of the truck after driving in hot weather. On 2003+, the charcoal vapor canister is mounted above the spare tire. Dropped the tire, did a visual check, and found this:
Two wires are broken leading into the connector to the vapor canister (no signs of chewing or other rodent clues). My understanding is that this means the vent valve on the vapor canister has not been energized, meaning no vapors released from the canister, and pressure has built up in the tank and canister, and most likely the canister needs to be replaced too.
This is the connector with the other half of the broken wires (that was still attached to the canister):
As you can see, there is no way to solder the wires (from the wiring harness) back to this connector.
I think that the best way to fix this is to find an LX parts truck, clip this part of the harness (with connector), then solder it on to my existing harness wires.
My best thought of a temporary fix is to attach blades and wires to the male side of the connector (part of the canister assembly), connect those wires to the existing wiring harness spur, and tape it all up. Here's the male connector on the canister:
And if I continue to drive it as is, loosen the gas cap.
I'm open to all other ideas, thanks.
