Evaporative Emission Control System Purge Control Valve Circuit Shorted?
RE: Evaporative Emission Control System Purge Control Valve Circuit Shorted?
It means that the evaporative system vacuum solenoid isn't firing. I had the exact same problem with mine recently. I took it in under warranty and they said they found a wire near the front drive shaft was rubbing. They cut 10" out and soldered in a new chunk. Then they wire tied back into the frame rail.
The solenoid is energized to pull a vacuum on your tank and charchol canister.
