Nissan Rogue · 2008–2013
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.
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.

- Genuine Nissan EVAP canister vent-control valve 14935-JF02C
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
- TipIf replacing the vent valve, inspect the canister and nearby hoses at the same time because debris or saturation can cause repeat failures.

Frequently asked questions
What does P0448 mean?
P0448 stands for "Evaporative Emission System Vent Control Circuit Shorted." This emissions code means the computer detected a short in the EVAP (evaporative emission) system's canister vent valve/solenoid control circuit: abnormally low voltage, a short to ground, or abnormal current draw where it expected the commanded signal. 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. 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 the system may not seal for leak checks.
What are the most common causes of P0448?
The most common causes of P0448 are: Failed EVAP vent valve/solenoid (shorted winding), Vent solenoid control wire shorted to ground or to another circuit, Corroded or water-damaged vent valve connector, Chafed harness near the canister (often under the vehicle), Faulty ECM/PCM driver circuit. The specific cause varies by vehicle.
How much does it cost to fix P0448?
Repair costs for P0448 range from $250 to $900, depending on the vehicle and root cause.
