Sounds like a good find - the Green wire is the VREF - Signal Return circuit.
Yea, I kinda saw this coming. I mustered enough gumption to get my creeper and check the canister vent valve and cable. ....looking for mouse chewing. The cable sheath was damaged but as far as I could peel it back the green and other wire looked OK.
...still a bit stiff from the surgery, but I reckon by next spring I'll be able to properly dig into most future issues. As a member of the Church of DIY, I'd rather eat a bar of soap than pay someone for something I can figure out and fix.
