Code P0444 Hyundai Description
The P0444 code for Hyundai vehicles indicates a problem with the Evaporative Emission System-Purge Control Valve Circuit being open. The Evaporative Emission Control (EVAP) system in a vehicle is responsible for capturing and storing fuel vapors to prevent them from being released into the atmosphere. The purge control valve is a crucial component of this system, as it controls the flow of fuel vapors from the charcoal canister to the engine for combustion.
Common Causes of P0444 Hyundai
- Faulty Purge Control Valve: The most common cause of this code is a malfunctioning purge control valve that is stuck open.
- Wiring Issues: Damage or corrosion in the wiring that connects the purge control valve to the ECM can cause an open circuit.
- Blown Fuse: A blown fuse in the EVAP system circuit can prevent the purge control valve from functioning properly.
- ECM Malfunction: A problem with the engine control module (ECM) can also trigger this code by disrupting communication with the purge control valve.
Symptoms of P0444 Hyundai
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the dashboard.
- Rough Idle: A faulty purge control valve can cause the engine to idle roughly or inconsistently.
- Decreased Fuel Efficiency: Since the EVAP system plays a role in fuel vapor management, a problem with the purge control valve can lead to decreased fuel efficiency.
- Strong Fuel Smell: If the purge control valve is stuck open, it can result in a strong smell of fuel around the vehicle.
How to Fix P0444 Hyundai
- Diagnose the Issue: Use an OBD-II scanner to retrieve the specific code and perform a thorough inspection of the EVAP system components.
- Test the Purge Control Valve: Check the purge control valve for proper operation by applying voltage to it and verifying that it opens and closes as intended.
- Inspect Wiring and Connections: Examine the wiring harness and connectors for any damage or corrosion, and repair or replace as necessary.
- Replace Purge Control Valve: If the purge control valve is found to be faulty, replace it with a new one that meets the manufacturer's specifications.
- Clear Codes and Test Drive: After completing the repairs, clear the diagnostic codes, reset the ECM, and test drive the vehicle to ensure that the issue has been resolved.
Cost to Fix P0444 Hyundai
The cost of repairing a P0444 code on a Hyundai vehicle can vary depending on the specific cause of the issue and the cost of parts and labor. On average, the cost of replacing a purge control valve can range from $150 to $300, while diagnosing and repairing wiring issues or an ECM malfunction may increase the total cost. Additionally, labor rates at auto repair shops can range from $80 to $150 per hour, so it's recommended to check with local shops for a more accurate estimate based on your location and vehicle model.

For Sonata with 2.4L engine, the Purge Control Solenoid Valve is on the side of the engine.

Hey I just replaced the pcv too and my code remained. Any idea why that happened?
-
Before I changed my purge valve I was getting codes p0441, p2189, 2187, and p0300. Changed my purge valve now I'm getting codes p0444 and p0303. What could be the cause for this? It's a 2008 hyundai santa fe 2.7

The EVAP Purge Solenoid Valve was probably the most likely cause of the P0441, P2189 and P2187 codes and even the P0444 code. My first recommendation is to double check the installation. After you replace the EVAP Purge Solenoid Valve, how long did it take for the code to show up?

Good day. Where is the location of EVAP purge solenoid valve. Hyundai matrix 2003 1.6 AT

My Accent 2009 was showing P0444. I changed the valve that goes behind the intake, close to the fire wall. Erased the check engine light and it goes fine until I turn off the engine and turn it on again. I checked the seal gasket on the fuel pump, it is OK. I took off the valve that goes under the canister and checked it as well, it seems to be fine. At least the solenoid is clicking on and off when I appy voltage. Then...what could it be ? Do you think I will have to change this valve too ? I do not think is the hose that goes to the other valve behind the intake. Give me some ideas please.
Thanks a lot,

By far the most common problem for the P0444 on your vehicle is the Evap Purge Solenoid Valve. Is that the valve you replaced? Other than that I have not seen any other component setting the code. Make the connector is firmly connected.

I replaced that valve you are indicating, but not the one under the charcoal canister. Do you think that could be the reason?
-
No.
Your next step is to check if you have power to the valve. If there is no power, then there is a problem with either the wire or the main relay. I doubt is the main relay, because that relay powers many other components and you'll have more codes.

There is power in the upper valve, I mean the one behind the intake. I have to check the one under the canister. But a month ago I applied voltage to this valve and as I said before, it was working. I will check the voltage on the socket today to see what the problem could be. Thanks, I will let you and the community know the results.
