P0441 2011 Nissan Pathfinder Code - Evaporative Control System Incorrect Purge Flow
Quick Answer
The Engine Control Module (ECM) tests the Evaporative Emission (EVAP) system for the following conditions: - Large and small leaks - Excess vacuum - Purge flow during non-commanded conditions - Fuel Level and Fuel Pressure sensor faults - EVAP Purge and Vent Valve faults The ECM monitors the Fuel Tank Pressure sensor in order to determine the level of vacuum/pressure in the EVAP system. Common causes include EVAP canister purge volume control solenoid valve stuck closed, EVAP control system pressure sensor and the circuit, Loose, disconnected or improper connection of rubber tube. 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 P0441 2011 Nissan Pathfinder Description
- Large and small leaks
- Excess vacuum
- Purge flow during non-commanded conditions
- Fuel Level and Fuel Pressure sensor faults
- EVAP Purge and Vent Valve faults
The ECM monitors the Fuel Tank Pressure sensor in order to determine the level of vacuum/pressure in the EVAP system. The ECM commands both the EVAP Purge Solenoid and the EVAP Vent Valve ON when the conditions are met in order to apply an engine vacuum to the EVAP system. The ECM commands the EVAP Purge Solenoid OFF once the system has reached a predetermined level of vacuum. This test verifies if a vacuum can be achieved in the EVAP system. Failure to develop a vacuum may be caused by a large leak or a restriction.
What are the Possible Causes of the DTC P0441 2011 Nissan Pathfinder?
- EVAP canister purge volume control solenoid valve stuck closed
- EVAP control system pressure sensor and the circuit
- Loose, disconnected or improper connection of rubber tube
- Blocked rubber tube
- Cracked EVAP canister
- EVAP canister purge volume control solenoid valve circuit
- Accelerator pedal position sensor
- Blocked purge port
- EVAP canister vent control valve

2. What are the common symptoms of code P0441 in a 2011 Nissan Pathfinder?
Symptoms may include the check engine light turning on, a slight decrease in fuel efficiency, and a faint fuel odor near the vehicle.
3. What causes the P0441 code in a 2011 Nissan Pathfinder?
Common causes include a faulty EVAP purge valve, loose or damaged fuel cap, clogged EVAP lines, or a vacuum leak in the EVAP system.
4. Can a loose gas cap trigger the P0441 code?
Yes, a loose or damaged gas cap is a common reason for the P0441 code and should be checked first.
5. How do I fix the P0441 code on my 2011 Nissan Pathfinder?
Start by tightening or replacing the gas cap. If the issue persists, inspect and replace the EVAP purge valve, check for vacuum leaks, or clean clogged EVAP system components.
6. Is it safe to drive with the P0441 code on my 2011 Nissan Pathfinder?
Yes, it is generally safe to drive, but ignoring the issue may lead to reduced fuel efficiency and potential long-term damage to the EVAP system.
7. How much does it cost to repair the P0441 code on a 2011 Nissan Pathfinder?
Repair costs vary, but gas caps typically cost $20-$50, while EVAP purge valve replacement can range from $150 to $300, including parts and labor.
8. Can a bad EVAP purge valve cause the P0441 code?
Yes, a malfunctioning EVAP purge valve is one of the most common causes of the P0441 code.
9. How do I diagnose the P0441 code on my 2011 Nissan Pathfinder?
Use an OBDII scanner to confirm the code, then inspect the gas cap, EVAP purge valve, and vacuum lines for damage, leaks, or blockages.
10. Will clearing the P0441 code solve the problem on my 2011 Nissan Pathfinder?
Clearing the code may turn off the check engine light temporarily, but it won’t fix the underlying issue causing the code to appear.
