P0444 2010 Nissan Pathfinder Code - EVAP Canister Purge Volume Control Solenoid Valve Circuit Open
Quick Answer
The P0444 diagnostic trouble code (DTC) for a 2010 Nissan Pathfinder indicates a problem with the EVAP (Evaporative Emission Control) system, specifically related to the Canister Purge Volume Control Solenoid Valve circuit being open. Common causes include Faulty Canister Purge Volume Control Solenoid Valve: The solenoid valve itself may be malfunctioning, causing the circuit to remain open, Wiring Issues: Damage to the wiring harness or connectors related to the solenoid valve can prevent proper electrical flow, Corrosion: Corrosion on the electrical connections can disrupt the circuit and trigger the P0444 code. 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 P0444 2010 Nissan Pathfinder Description
The P0444 diagnostic trouble code (DTC) for a 2010 Nissan Pathfinder indicates a problem with the EVAP (Evaporative Emission Control) system, specifically related to the Canister Purge Volume Control Solenoid Valve circuit being open. The EVAP system is designed to capture and store fuel vapors from the fuel tank to prevent them from escaping into the atmosphere. The Canister Purge Volume Control Solenoid Valve is responsible for controlling the flow of fuel vapor from the charcoal canister to the engine intake manifold for combustion.
Common Causes of P0444 2010 Nissan Pathfinder
- Faulty Canister Purge Volume Control Solenoid Valve: The solenoid valve itself may be malfunctioning, causing the circuit to remain open.
- Wiring Issues: Damage to the wiring harness or connectors related to the solenoid valve can prevent proper electrical flow.
- Corrosion: Corrosion on the electrical connections can disrupt the circuit and trigger the P0444 code.
- ECM (Engine Control Module) Failure: A malfunctioning ECM can also lead to issues with the EVAP system and trigger this code.
Symptoms of P0444 2010 Nissan Pathfinder
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the vehicle's dashboard.
- Rough Idle: A malfunctioning EVAP system can cause the engine to idle roughly or inconsistently.
- Decreased Fuel Efficiency: A faulty EVAP system can lead to increased fuel consumption due to the improper handling of fuel vapors.
- Strong Fuel Odor: If the EVAP system is not functioning correctly, you may notice a strong smell of fuel around the vehicle.
How to Fix P0444 2010 Nissan Pathfinder
- Diagnose the Issue: Use a scan tool to retrieve the DTC and perform further testing to pinpoint the exact cause of the P0444 code.
- Inspect Wiring and Connections: Check the wiring harness and connectors for any signs of damage or corrosion. Repair or replace as needed.
- Test the Solenoid Valve: Test the Canister Purge Volume Control Solenoid Valve to determine if it is functioning properly. Replace if necessary.
- Clear DTC and Test Drive: After making the necessary repairs, clear the DTC from the ECM and test drive the vehicle to ensure the issue has been resolved.
- Perform EVAP System Leak Test: To ensure the entire EVAP system is functioning correctly, perform a leak test to check for any additional issues.
Cost to Fix P0444 2010 Nissan Pathfinder
The typical repair costs for addressing a P0444 code on a 2010 Nissan Pathfinder can vary depending on the specific cause of the issue. In general, you can expect to pay anywhere from $100 to $300 for parts and labor. Keep in mind that diagnostic time and labor rates at auto repair shops can vary, with hourly rates typically ranging from $80 to $150.

Frequently Asked Questions about P0444 2010 Nissan Pathfinder Code
1. What does code P0444 mean on a 2010 Nissan Pathfinder?
Code P0444 indicates an "EVAP Canister Purge Volume Control Solenoid Valve Circuit Open," meaning there is a problem with the electrical circuit controlling the purge valve in the EVAP system.
2. What are the symptoms of code P0444 in a 2010 Nissan Pathfinder?
Common symptoms include the Check Engine Light turning on, possible fuel odor near the vehicle, decreased fuel efficiency, and difficulty passing an emissions test.
3. What causes the P0444 code to appear?
The main causes include a faulty purge volume control solenoid valve, damaged or corroded wiring, a disconnected electrical connector, or a failed ECM.
4. Is it safe to drive a 2010 Nissan Pathfinder with a P0444 code?
Yes, the vehicle can still be driven, but it may experience reduced fuel efficiency and increased emissions. Prolonged driving without repair could lead to additional issues.
5. How do I fix the P0444 code on my 2010 Nissan Pathfinder?
Start by inspecting the purge valve and its wiring for damage or disconnection. Replace the purge valve if necessary and repair or replace any damaged wiring or connectors.
6. Where is the EVAP purge volume control solenoid valve located on a 2010 Nissan Pathfinder?
The purge valve is typically located near the engine, mounted on or near the intake manifold. Refer to the vehicle’s service manual for the exact location.
7. Can a loose gas cap cause the P0444 code?
No, a loose gas cap generally triggers a different EVAP-related code, such as P0455 or P0456. P0444 specifically relates to the purge valve circuit.
8. How much does it cost to fix a P0444 code on a 2010 Nissan Pathfinder?
