P0441 on Nissan by model: symptoms, diagnosis and fix
The Quest rear A/C system fails prematurely due to the rear evaporator developing leaks. The rear A/C then blows warm air while the front works normally. The rear expansion valve can also stick, preventing proper refrigerant flow. Repairing the rear A/C requires significant disassembly of interior panels.
Common Symptoms
- Rear A/C blows warm air
- Front A/C works but rear does not
- Hissing noise from rear A/C area
- A/C system low on refrigerant frequently
- Moisture or ice under rear of vehicle
How to Fix
Diagnose whether the rear evaporator or expansion valve has failed. Replace rear evaporator (requires interior panel removal, $800-1,500 labor-intensive). Replace rear expansion valve if stuck. Recharge A/C system after repair.

Frequently asked questions
What does P0441 mean on a Nissan?
P0441 stands for "Evaporative Emission Control System Incorrect Purge Flow." This code means the Engine Control Module (ECM) detected an incorrect amount of purge flow in the Evaporative Emission Control (EVAP) system. The EVAP system captures gasoline vapors from the fuel tank in a charcoal canister and then 'purges' them into the engine to be burned, controlled by a purge valve. P0441 sets when the computer commands the purge valve open or closed but sees the wrong flow — too much, too little, or none at the wrong time. It is an emissions/sealing issue, not something that usually affects driving, though you may notice a fuel smell. On Nissan it is documented across 1 model: Quest.
What are the most common causes of P0441?
The most common causes of P0441 are: Stuck-open or stuck-closed EVAP purge valve/solenoid, Failed or stuck EVAP vent valve, Loose, damaged, or missing gas cap, Cracked or disconnected EVAP/purge vacuum hoses, Faulty purge flow or pressure sensor, Clogged or saturated charcoal canister, Wiring or connector fault to the purge valve. The specific cause varies by vehicle.
How much does it cost to fix P0441 on a Nissan?
Published repair estimates on Nissan range from $400 to $1,500 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
