P0441 2012 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 2012 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 2012 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 a P0441 code in a 2012 Nissan Pathfinder?
Symptoms may include an illuminated check engine light, a slight decrease in fuel efficiency, and, in some cases, a faint fuel smell near the vehicle.
3. What causes the P0441 code in a 2012 Nissan Pathfinder?
Common causes include a faulty purge valve, clogged or damaged EVAP lines, a leaking gas cap, or a malfunctioning EVAP canister.
4. Can a loose or damaged gas cap cause a P0441 code?
Yes, a loose or damaged gas cap can disrupt the EVAP system and trigger the P0441 code. Always check the gas cap first.
5. How is the P0441 code diagnosed in a 2012 Nissan Pathfinder?
A technician will inspect the gas cap, EVAP system hoses, purge valve, and canister for leaks or damage. They may also perform a smoke test to identify leaks.
6. Can I drive my 2012 Nissan Pathfinder with a P0441 code?
Yes, you can typically drive with a P0441 code, but it’s best to address it promptly to avoid potential EVAP system damage and increased emissions.
7. How do you fix the P0441 code on a 2012 Nissan Pathfinder?
Repairs may involve replacing the purge valve, repairing or replacing damaged EVAP hoses, tightening or replacing the gas cap, or replacing the charcoal canister.
8. How much does it cost to fix a P0441 code on a 2012 Nissan Pathfinder?
Repair costs vary, but replacing a purge valve typically costs $150–$300, while fixing hoses or replacing the gas cap is usually less expensive.
9. Can a faulty purge valve trigger a P0441 code in a 2012 Nissan Pathfinder?
Yes, a stuck open or closed purge valve is one of the most common causes of the P0441 code.
10. Will clearing the P0441 code fix the problem permanently?
