P0444 Hyundai Code - Evaporative Emission System-Purge Control Valve Circuit Open
Quick Answer
The evaporative emission control system prevents hydrocarbon (HC) vapors from the fuel tank from escaping into the atmosphere where they could form photochemical smog. Common causes include Faulty Evaporative Emission (EVAP) Purge Control Solenoid Valve (PCSV), Purge Control Solenoid Valve harness is open or shorted, Purge Control Solenoid Valve circuit poor electrical connection. 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.

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.
