P0441 2006 Nissan Maxima 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 Maxima 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 Maxima?
- 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

1. What does the OBDII code P0441 mean for a 2006 Nissan Maxima?
P0441 indicates an issue with the evaporative emission (EVAP) control system, specifically incorrect purge flow, meaning the system is not properly regulating fuel vapor flow.
2. What are the symptoms of code P0441 in a 2006 Nissan Maxima?
Common symptoms include the check engine light turning on, reduced fuel efficiency, and a possible faint fuel smell around the vehicle.
3. What causes the P0441 code in a 2006 Nissan Maxima?
Possible causes include a faulty purge control valve, a loose or damaged gas cap, clogged EVAP lines, or issues with the EVAP canister.
4. Can a loose gas cap trigger the P0441 code in a 2006 Nissan Maxima?
Yes, a loose or improperly sealed gas cap can cause the P0441 code by disrupting the vacuum pressure in the EVAP system.
5. How do you fix the P0441 code on a 2006 Nissan Maxima?
Repairs may include tightening or replacing the gas cap, inspecting and replacing the purge valve or EVAP canister, and checking for leaks or clogs in the EVAP hoses.
6. Is it safe to drive a 2006 Nissan Maxima with the P0441 code?
Yes, it is generally safe to drive, but ignoring the issue can lead to decreased fuel efficiency or potential damage to the EVAP system over time.
7. How do you diagnose the P0441 code in a 2006 Nissan Maxima?
Diagnose by using an OBDII scanner to confirm the code, visually inspecting the gas cap and EVAP components, and testing the purge valve for proper operation.
8. How much does it cost to repair the P0441 code on a 2006 Nissan Maxima?
Repair costs vary but might range from $20 for a new gas cap to $200-$400 for a new purge valve or canister, plus labor charges if done by a mechanic.
9. Can a clogged EVAP canister cause the P0441 code in a 2006 Nissan Maxima?
Yes, a clogged or damaged EVAP canister can restrict fuel vapor flow and trigger the P0441 code.
10. Will clearing the P0441 code solve the problem on a 2006 Nissan Maxima?
Clearing the code will turn off the check engine light temporarily, but the issue will likely return unless the underlying problem is fixed.
