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 is the cause of a code p0442 leak?
What Is The Cause Of Code P0442? 1 Loose or damaged gas cap 2 Leaking or disconnected EVAP hose 3 Faulty purge volume control valve 4 Faulty canister vent control valve 5 Charcoal canister leak 6 Leaking fuel tank
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 does code p0442 mean on a charcoal canister?
What Does Code P0442 Mean? The evaporative emission control (EVAP) system prevents fuel vapors from escaping into the atmosphere. The fuel vapors from the fuel tank are absorbed and stored by charcoal pellets in the charcoal canister.
What causes the p0444 OBD-II trouble code?
The P0444 code refers to a detected issue with the EVAP circuit. This may relate to a malfunction or disconnection with one of the system’s components, including (but not limited to) the system pressure and flow sensors, electrical wiring, the fuel tank and lines, or the gas cap.

What is the PCM error code for the purge valve?
The PCM checks the voltage to the purge control valve, and if it unable to detect change with purge valve commanded on, it will trigger the Error Code P0444. This code is pretty similar to Error Code P0443 and P0445. As with other error codes, this code activates the Check Engine light, which is also its most common and noticeable symptom.
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 is the code for the purge valve?
NOTE #1: Code P0444 specifically refers to issues in the purge valve control circuit, and leaks in the system, or issues with other EVAP circuits/components will typically not set this code.
What does the PCM code p0444 mean?
All of these are controlled by the PCM (powertrain control module, also known as ECM or engine control module in other makes). The PCM checks the voltage to the purge control valve, and if it unable to detect change with purge valve commanded on, it will trigger the Error Code P0444.
