P0447 on Nissan
Evaporative Emission System Vent Control Circuit Open
P0447 on Nissan vehicles indicates evaporative emission system vent control circuit open. Au7o has documented this code across 1 Nissan model — most commonly on Rogue. This code means the engine computer detected an electrical open (broken or disconnected circuit) in the control wiring for the EVAP system's vent valve, which lets fresh air into the charcoal canister that captures fuel vapors. Because the computer can no longer command the vent valve to open or close, it cannot properly seal the fuel system to test for vapor leaks. This is an emissions and self-test issue rather than a safety or driveability problem, so the car generally runs fine but will fail an emissions test. Typical repair costs on Nissan range from $250 to $900, depending on the specific model and root cause.
Common Causes of P0447
- •Faulty EVAP vent valve/solenoid (internal electrical failure)
- •Damaged, corroded, or disconnected wiring to the vent solenoid
- •Bad or loose electrical connector at the vent valve
- •Open circuit or chafed wire in the EVAP harness
- •Blown fuse feeding the vent control circuit
- •Vent valve clogged with dirt or debris
- •PCM/ECM driver fault (rare)

- EVAP Vent Control Valve / Charcoal Canister Faults Triggering Check Engine Light and Hard Refueling2008-2013
Rogue owners commonly report EVAP system faults caused by a sticking vent control valve, contaminated canister, or related hose issues. The problem often shows up as a persistent check engine light and, in some cases, the gas pump repeatedly clicks off during refueling because the tank cannot vent properly. Nissan service literature for EVAP leak and vent valve diagnosis exists, and complaint/forum activity is consistent across this generation.
