Evaporative Emission System Vent Control Circuit Shorted

What it means

Indicates that the Engine Control Module (ECM) has detected a short-to-ground or short-to-voltage condition in the EVAP vent valve control circuit. Note: Modern heavy-duty diesel trucks rarely use gasoline-style EVAP systems; this code typically appears on dual-fuel units or is misreported by generic scanners for specific EGR/SCR solenoid faults.
