P0445 2008 Nissan Pathfinder Code - EVAP Canister Purge Volume Control Solenoid Valve Circuit Shorted

P0445 indicates that the EVAP Canister Purge Volume Control Solenoid Valve Circuit has a short, meaning there’s an electrical issue causing improper operation of the purge valve in the EVAP system.

Common symptoms include the check engine light turning on, reduced fuel efficiency, a noticeable fuel odor, and potentially difficulty starting the engine.

The code is often caused by a short circuit in the purge valve, damaged wiring or connectors in the EVAP system, a faulty purge valve, or an issue with the engine control module (ECM).

While the vehicle may still be drivable, it’s not recommended to ignore this code as it can lead to increased emissions and potential long-term damage to the EVAP system.

Repairs typically involve inspecting and repairing damaged wiring or connectors, replacing the EVAP canister purge volume control solenoid valve if faulty, and clearing the code using an OBDII scanner.

You can test the purge valve by checking for proper resistance with a multimeter. If the resistance is outside the manufacturer’s specifications, the valve is likely faulty and needs replacement.

No, a loose or damaged gas cap usually triggers a different EVAP-related code, such as P0455 or P0456, rather than P0445, which is specific to the purge valve circuit.

You’ll need an OBDII scanner, a multimeter for electrical testing, and basic hand tools to inspect and replace components if necessary.

The cost depends on the exact issue. Replacing the purge valve typically costs between $100 and $200, including parts and labor, while wiring repairs may vary based on the extent of the damage.

While you can clear the code with an OBDII scanner, it will likely return if the underlying issue is not resolved. It’s best to address the root cause to prevent further complications.
