Code P2406 KIA Description

The Diagnostic Module Tank Leakage (DM-TL) is used to monitor the evaporative system for leaks. The diagnostic module consists of an air filter, an electrically driven air pump, a change-over valve, and a 0.02-inch orifice for reference measurement. Heated type Module applied to improved Leakage Detection Module. Using the heated DM-TL can completely eliminate the humidity influence. So, the Leakage detection never stopped caused of the current fluctuation (due to dew effects at extreme high humidity). If the value exceeds the threshold value, the Powertrain Control Module (PCM) judges this as a fault, and a Diagnostic Trouble Code (DTC) is set.
