General Description
The evaporative emission control system prevents hydrocarbon (HC) vapors from the fuel tank from escaping into the atmosphere where they could form photochemical smog. Gasoline vapors are collected in the charcoal canister. The ECM controls the Purge Control Solenoid Valve (PCSV) to purge any collected vapors from the canister back to the engine for combustlon. This valve is actuated by the purge control signal from the PCM and controls fuel vapor from the canister to the intake manifold.
Possible Cause : ● Leakage on hose to PCSV ● Defective PCSV

1. Ignition "OFF" 2. Disconnect the hose leading from the PCSV to the intake manifold at PCSV 3. Using a vacuum pump, apply specified vacuum(Approx. 15 in, Hg) to the manifold side of the valve and verify PCSV holds vacuum. 4. Ignition "ON" & Engine "OFF" 5. Install scantool and select "EVAP PURGE VALVE" on the Actuation Test mode 6. Activates "EVAP PURGE VALVE" by pressing "STRT(F1)" key 7. Verify PCSV release vacuum while valve is activating(should hear a faint click from PCSV) 8. Repeat this procedure 4 or 5 times to ensure PCSV reliability. 9. Is PCSV working properly? YES ▶ Thoroughly check fuel vapor hoses and hose clamp and replace as necessary. Go to "Terminal and connection inspection" procedure. NO ▶ Thoroughly check fuel vapor hoses and hose clamps between PCSV and intake manifold. Repair as necessary. If OK, test with a new PCSV and check for proper operation. If problem is corrected, replace PCSV and go to "Verification of Vehicle Repair" procedure
1. Many malfunctions in the electrical system are caused by poor harness(es) and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage. 2. Check the following conditions: (1) Check for damaged harness and terminals: contact resistance, oxidation, bent or broken terminals. (2) Check for poor connection between PCM and component: backed out terminal, improper mating, broken locks and poor terminal to wire connection. 3. Is a problem found? YES ▶ Repair as necessary and go to "Verification of Vehicle Repair" procedure. NO ▶ Check for poor connection between PCM and component: backed out terminal, improper mating, broken locks or poor terminal to wire connection. Repair as necessary and go to "Verification of Vehicle Repair" procedure. Using a suitable male pin to ensure that contact in sockets is good. The pin should remain in position when pulled gently.
Check canister solenoid purge valve,it is probably youre problem! stuck open,

It is always best to start simple on a lot of these things. This code indicates that somewhere in the evaporative system you have a leak that has set off the code. The gas cap is the most common culprit and that is where I would start. Buy a new gas cap and put it on. It may and should solve your problem. A lot of gas caps have rubber seals that do wear out over time. If this does not solve your problem simply use a search engine and type in p0441 a wealth of information will pop up. There are other possible causes and solutions but that's where I would start (with the gas cap)

There is an evap purge valve located in the back of the driver side of the engine. This valve needs to be replaced. Had the same code a couple weeks ago. Replaced that valve and the problem was fixed. Hope this helps.
