Yeah, it almost has to be a bad vent solenoid, or a broken connection in the wiring to it. This code is saying that the PCM is not seeing the voltage change when it grounds the vent solenoid to activate it.
Should have system voltage at one terminal with the ignition on, and a ground at the other terminal when the PCM commands the vent valve open.
