P0441 2006 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 2006 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 2006 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 2006 Nissan Pathfinder?
Symptoms may include the check engine light turning on, a noticeable fuel odor, reduced fuel efficiency, or difficulty passing an emissions test.
3. What causes the P0441 code to appear on a 2006 Nissan Pathfinder?
Common causes include a faulty purge valve, a clogged or damaged EVAP line, a loose or damaged gas cap, or issues with the EVAP canister.
4. Is it safe to drive with a P0441 code on my 2006 Nissan Pathfinder?
Yes, the vehicle can still be driven, but ignoring the issue may lead to reduced fuel efficiency and potential long-term damage to the EVAP system.
5. How can I diagnose the P0441 code on a 2006 Nissan Pathfinder?
Diagnose the issue by checking the gas cap for damage, inspecting the EVAP lines and purge valve, and using a smoke test to find leaks in the system.
6. Can a loose gas cap cause the P0441 code on a 2006 Nissan Pathfinder?
Yes, a loose or damaged gas cap can cause the EVAP system to malfunction, triggering the P0441 code.
7. How do I fix the P0441 code on my 2006 Nissan Pathfinder?
Start by tightening or replacing the gas cap, inspecting and replacing the purge valve if faulty, and checking for damaged EVAP lines or canisters.
8. How much does it cost to repair a P0441 issue on a 2006 Nissan Pathfinder?
Repair costs can vary, but replacing a gas cap may cost $20-$50, while replacing a purge valve or fixing leaks in the EVAP system could range from $150 to $400.
9. Will clearing the P0441 code solve the issue permanently?
Clearing the code without addressing the root cause will likely result in the code returning. Proper diagnosis and repair are necessary for a permanent fix.
10. Can an OBDII scanner help resolve the P0441 code on a 2006 Nissan Pathfinder?
An OBDII scanner can read and clear the code, but it’s also useful for identifying related codes and monitoring EVAP system performance during diagnosis.
