The Toyota Techstream software allows the tech to test the EVAP system, oftentimes isolating a leak quickly. The software tests theintake valve.
The vapor fills the EVAP system and exists the air drain hose.

Q: If there is a leak in the system, how does the tech perform a leak check? What leak tests do you begin with?

This component is there as an aid in diagnosing the presence of leakage before moving on to the next step of locating revealed leakage with the aid of visible vapor. For the systems in the model years listed above, to determine the presence of a leak:
