Hyundai evap

When testing evap systems for problems don't forget about the ORVR. The complaint on this Hyundai is difficult to fill fuel, the pump keeps shutting off. Someone has already replaced the canister and the vent valve.

Here is what I found. Hyundai calls it the Fill vent valve (ORVR) and it is mounted on top of the fuel tank. [2002 Hyundai XG350 L, ECM/Inputs/Outputs Photo] [2002 Hyundai XG350 L, ECM/Inputs/Outputs Waveform]

Look at all the charcoal that came out. The valve was stuck closed. [2002 Hyundai XG350 L, ECM/Inputs/Outputs Photo]
