The EVAP leak check module change valve is installed in the EVAP leak check module and used to seal up the EVAP passage when performing the EVAP leak check. The EVAP leak check module change valve is normally open (open to the atmosphere) and only closed (sealed) when performing the EVAP leak check. The powertrain control module (PCM) detects a malfunction and stores a DTC when the close signal is returned continuously for the prescribed time or more though close signal is not output to the EVAP leak check module change valve.
