P0448 on Nissan
Evaporative Emission Control System Vent Valve/Solenoid Circuit Open
P0448 on Nissan vehicles indicates evaporative emission control system vent valve/solenoid circuit open. Au7o has documented this code across 1 Nissan model — most commonly on Rogue. This emissions code indicates the EVAP (evaporative emission) system's vent valve/solenoid circuit is reading as electrically open. The vent valve controls how fresh air enters the charcoal canister and is part of how the system seals itself to test for fuel-vapor leaks. When the computer commands the vent solenoid but its circuit stays open (no continuity), this code sets — it's an electrical fault in the valve or its wiring, not a fuel or driveability problem. You typically won't feel any difference in how the car runs, but it will fail an emissions test and may not seal for leak checks. Typical repair costs on Nissan range from $250 to $900, depending on the specific model and root cause.
Common Causes of P0448
- •Failed EVAP vent valve/solenoid (open winding)
- •Open or broken wiring in the vent solenoid circuit
- •Corroded or disconnected vent valve connector
- •Poor power or ground feed to the solenoid
- •Damaged harness near the canister (often under the vehicle)
- •Blown fuse supplying the EVAP solenoid
- •Faulty ECM/PCM driver circuit
P0448 on Nissan by Model
Nissan Rogue(1 issue)
- 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.

What does P0448 mean on Nissan?▼
P0448 stands for "Evaporative Emission Control System Vent Valve/Solenoid Circuit Open." This emissions code indicates the EVAP (evaporative emission) system's vent valve/solenoid circuit is reading as electrically open. The vent valve controls how fresh air enters the charcoal canister and is part of how the system seals itself to test for fuel-vapor leaks. When the computer commands the vent solenoid but its circuit stays open (no continuity), this code sets — it's an electrical fault in the valve or its wiring, not a fuel or driveability problem. You typically won't feel any difference in how the car runs, but it will fail an emissions test and may not seal for leak checks. On Nissan specifically, this code is documented across 1 model.
