Summary. The evaporative emission control (EVAP) system traps fuel vapors in a vapor canister, preventing them from being released into the atmosphere. EVAP systems can leak after some time. Depending on the size of the leak, the powertrain control module (PCM) can store a few related diagnostic trouble codes (DTCs).The EVAP canister purge check valve test is performed during minimal boost conditions, once per drive cycle, when entry conditions are met. The DTC is set if the fuel tank pressure exceeds a calibrated amount within a specified amount of time during the test. P144C Code - Evaporative Emission System Purge Check Valve Performance
