P0455

Description

The DM-TL (Diagnostic Module Tank Leakage) is used to monitor the evaporative system for leaks. The diagnostic module consists of an air filter, an electrical driven air pump, a changeover 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 is never stopped caused by the current fluctuation (due to dew effects at extreme high humidity).

The ECM sets DTC P0455 if ECM detects the current value is less than threshold value.
