P0445 2008 Nissan Pathfinder Code - EVAP Canister Purge Volume Control Solenoid Valve Circuit Shorted
Quick Answer
The Evaporative Emission System (EVAP) Canister Purge Volume Control Solenoid Valve controls flow rate of fuel vapor from the EVAP canister. Common causes include Faulty Evaporative Emission (EVAP) Purge Solenoid Control, Evaporative Emission (EVAP) Purge Solenoid Control harness is open or shorted, Evaporative Emission (EVAP) Purge Solenoid Control circuit poor electrical connection. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.

Code P0445 2008 Nissan Pathfinder Description
The EVAP canister purge volume control solenoid valve uses a ON/OFF duty to control the flow rate of fuel vapor from the EVAP canister. The EVAP canister purge volume control solenoid valve is moved by ON/OFF pulses from the ECM. The longer the ON pulse, the greater the amount of fuel vapor that will flow through the valve.
What are the Possible Causes of the DTC P0445 2008 Nissan Pathfinder?
- Faulty Evaporative Emission (EVAP) Purge Solenoid Control
- Evaporative Emission (EVAP) Purge Solenoid Control harness is open or shorted
- Evaporative Emission (EVAP) Purge Solenoid Control circuit poor electrical connection
How to Fix the DTC P0445 2008 Nissan Pathfinder?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.

Frequently Asked Questions about P0445 2008 Nissan Pathfinder Code
1. What does the OBDII code P0445 mean for a 2008 Nissan Pathfinder?
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.
2. What are the symptoms of the P0445 code on a 2008 Nissan Pathfinder?
Common symptoms include the check engine light turning on, reduced fuel efficiency, a noticeable fuel odor, and potentially difficulty starting the engine.
3. What causes the P0445 code to appear on a 2008 Nissan Pathfinder?
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).
4. Is it safe to drive my 2008 Nissan Pathfinder with the P0445 code?
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.
5. How do I fix the P0445 code on a 2008 Nissan Pathfinder?
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.
6. How can I test the EVAP canister purge solenoid valve for the P0445 code?
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.
7. Can a loose or damaged gas cap cause the P0445 code?
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.
8. What tools are needed to diagnose the P0445 code on a 2008 Nissan Pathfinder?
You’ll need an OBDII scanner, a multimeter for electrical testing, and basic hand tools to inspect and replace components if necessary.
9. How much does it cost to repair the P0445 code on a 2008 Nissan Pathfinder?
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.
10. Can I clear the P0445 code without fixing the issue?
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.
