P0447 on Nissan by model: symptoms, diagnosis and fix
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.
Common Symptoms
- Check engine light on
- Gas pump shuts off repeatedly while refueling
- Small or large EVAP leak codes
- Fuel odor near rear of vehicle
- Failed emissions inspection
How to Fix
Diagnosis includes smoke-testing the EVAP system, checking vent valve operation, inspecting the canister for saturation or debris, and verifying hose integrity near the rear of the vehicle. Repair may involve replacing the EVAP vent control valve, charcoal canister, damaged hoses, or corroded connectors, then clearing codes and confirming monitor completion.

Not the engine-bay purge valve. The 2008-2010 drain-cut 14935-AM60B branch is excluded because its inspected OE listing was unavailable; confirm VIN and production date.

Owner tips & cautions

Frequently asked questions
What does P0447 mean on a Nissan?
P0447 stands for "Evaporative Emission System Vent Control Circuit Open." 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. On Nissan it is documented across 1 model: Rogue.
What are the most common causes of P0447?
The most common causes of P0447 are: 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). The specific cause varies by vehicle.
How much does it cost to fix P0447 on a Nissan?
Published repair estimates on Nissan range from $250 to $900 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
