Possible causes

– Faulty Evaporative Emission (EVAP) Purge Solenoid Control Valve
– Evaporative Emission (EVAP) Purge Solenoid Control Valve harness is open or shorted
– Evaporative Emission (EVAP) Purge Solenoid Control Valve circuit poor electrical connection

When is the code detected?

– An excessively low voltage signal is sent to ECM through the valve

Symptoms

– Engine Light ON (or Service Engine Soon Warning Light)

P0444 2005 KIA SORENTO Description

The Evaporative Emission Control System (EVAP) 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 Engine Control Module (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 ECM and controls fuel vapor flow from the canister to the intake manifold.
