Here is how the evaporative leak test is performed by the Powertrain Computer:
Can a p0442 cause a vent valve to leak?
It is important to address these codes before you attempt to repair the P0442. Purge Valve or Vent Valve codes (P0446, P0443) can trigger a P0442. If the Vent Valve or Purge Valve is not functioning correctly, it may lead to a small leak that will set the P0442.
