Why does my Kia Rio have a p0444 code?
Code P0444 was finally resolved by replacing a cracked air manifold intake hose. It now runs smoother but once the… My Kia Rio is reading a P0444 code: Evaporative Emission System Purge Control Valve Circuit Open. I replaced the Purge Control Valve in May and am now getting the same code again. I understand the valve is normally closed.
What are the symptoms of a p0444 trouble code?
Symptoms of a P0444 trouble code may include: Check engine light on (Malfunction indicator lamp illuminated) Slightly diminished fuel economy, this will not affect engine performance
What does p0446 mean on Check Engine light?
However, as with all check engine light diagnostic trouble codes, you should repair it as soon as possible to return the vehicle to normal operation. Scan your vehicle to verify P0446 is the only code present. If other codes are present regarding fuel pressure or the fuel system, repair and diagnose those first.
What does p0404 mean on an EGR sensor?
Often times code P0404 does not actually indicate that there is something wrong with the EGR valve itself, but actually that the EGR sensor is telling your PCM that the proper amount of EGR needed to flow back into your cylinders and cool them is not present.
What is the OBD 2 fault code p0444?
OBD II fault code P0444 is defined as “Evaporative Emission Control System Purge Control Valve Open Circuit”, and is set when the PCM (Powertrain Control Module) detects a malfunction in the circuit that controls the purge valve in the EVAP (Evaporative Emission Control) system, or sometimes a malfunction of the purge valve itself.

What causes a p0443 purge control circuit?
To cause a P0443, there has to be a problem with the purge control CIRCUIT , not necessarily the valve. Usually they are a unit housing the valve and the solenoid as an assembly. Or it could be comprised of a separate solenoid with vacuum lines to a purge valve. That said, it could be any of the following:
What are the symptoms of trouble code p0443?
P0443 trouble code symptoms could be just an malfunction indicator lamp (MIL) illumination. There may be no drivability problems at all. But, it’s also possible to have a lean condition or a rough running engine if the purge valve is stuck open. Usually though, these symptoms are accompanied by other EVAP codes.

How to check for a purge control solenoid?
Purge control solenoid – Check for continuity at the purge control solenoid connector pins after removing the harness plug using the DVOM set to the ohms scale. Verify resistance is within manufacturers specifications. If no continuity is present, suspect the solenoid is internally open and replace the part with a known good unit.
What does p0449 stand for on Kia Optima?
P0449 deals with the evaporative emissions control (EVAP) system. It often appears with, or is related other codes, such as P0420, P0446, and very often P0455. P0449 is normally not an immediate threat to the drive-ability of your Optima.
What does a fault code of p0444 mean?
Fault Code Definition. Under precise operating conditions—dictated by engine temperature, speed, and load—the EVAP system stores and purges these captured fuel vapors back into the combustion process. Code P0444 indicates that there is improper purge flow in the EVAP system caused by an open purge valve circuit.
Why is the purge valve closed on an OBD?
When the leak test initiates, the Vapor Canister Vent Valve is closed to prevent any fresh air from entering the EVAP system. The Purge Valve is opened, which allows the engine to create a vacuum in the EVAP system.
