P0445 2012 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 2012 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 2012 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 2012 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 2012 Nissan Pathfinder Code
1. What does the OBDII code P0445 mean on a 2012 Nissan Pathfinder?
P0445 indicates a problem in the EVAP (Evaporative Emission Control) system, specifically that the Canister Purge Volume Control Solenoid Valve circuit is shorted.
2. What are the common symptoms of code P0445 in a 2012 Nissan Pathfinder?
Symptoms may include the check engine light turning on, a noticeable fuel odor, reduced fuel efficiency, or difficulty starting the vehicle.
3. What causes the P0445 code to appear on a 2012 Nissan Pathfinder?
The most common causes include a short circuit in the solenoid valve, a faulty purge valve, damaged wiring or connectors, or an issue with the vehicle's ECM (Engine Control Module).
4. Can I still drive my 2012 Nissan Pathfinder with a P0445 code?
Yes, you can still drive the vehicle, but it’s not recommended to ignore the issue as it may lead to increased emissions, poor efficiency, or more severe EVAP system damage over time.
5. How do I fix the P0445 code on a 2012 Nissan Pathfinder?
Repairs may involve replacing the EVAP canister purge solenoid, repairing or replacing damaged wiring, or addressing any related electrical issues in the circuit.
6. How much does it cost to fix a P0445 code on a 2012 Nissan Pathfinder?
The cost typically ranges from $100 to $300, depending on whether just the purge valve or additional components need replacement, as well as labor rates in your area.
7. How can I test the EVAP purge solenoid valve for a P0445 code?
You can test the valve using a multimeter to check for continuity or resistance. A short circuit would typically show zero resistance or a very low reading.
8. Is a faulty gas cap related to code P0445 on a 2012 Nissan Pathfinder?
No, a faulty gas cap is unlikely to cause a P0445 code, as this code specifically relates to the purge solenoid valve circuit.
9. Can clearing the P0445 code fix the problem on my 2012 Nissan Pathfinder?
Clearing the code may reset the check engine light temporarily, but it won't resolve the underlying issue causing the code to appear.
10. What tools are needed to diagnose the P0445 code on a 2012 Nissan Pathfinder?
You’ll need an OBDII scanner, a multimeter for electrical testing, and possibly a repair manual or wiring diagram specific to your vehicle.
