Evaporative Emission Purge Solenoid Check

WARNING: This page is about a different car, the 2012 Mitsubishi Lancer. However, it is still accessible from the selected car via links, so may be relevant.
  1. Disconnect the vacuum hose (black, black with red paint mark) from the evaporative emission (EVAP) purge solenoid.
    NOTE: When disconnecting the vacuum hose, always place an identification mark so that it can be reconnected at its original position.
  2. Disconnect the harness connector.
  3. Connect a hand vacuum pump to nipple (A) of the EVAP purge solenoid (refer to the illustration).
  4. As described in the chart below, check airtightness by applying a vacuum with voltage applied directly from the battery to the EVAP purge solenoid valve and without applying voltage.
