DTC Description

WARNING: This page is about a different car, the 2021 Kia Seltos. However, it is still accessible from the selected car via links, so may be relevant.

The ECM/PCM closes the Canister Close Valve (CCV) at the charcoal canister to seal off the evaporative emission system and then opens Purge Control Solenoid Valve (PCSV) to generate a vacuum in the fuel tank. After vacuum generation, the ECM/PCM measures pressure differential curve in the fuel tank and sets DTC P044200 if the vacuum generated within a monitoring period increases above a defined threshold.

If same error code is set in the next driving cycle, the ECM/PCM illuminates the MIL.
