Then the bypass valve opens, connecting the tank side of the system with the canister side during the monitor’s leak check.
Can EVAP purge valve cause loss of power?
Poor Engine Performance On top of a rough idle, a vehicle with a failing EVAP canister purge valve will display signs of poor engine performance. The engine may feel like its running “weak” and won’t generate sufficient power for acceleration.

Solenoid Bypass The thermal switch is attached to the suction pressure line at the evaporator outlet manifold. The electrical contacts in the switch are connected in series with the temperature control switch and the solenoid bypass valve winding. In the normal position, the contacts are closed.
Does EVAP purge valve affect gas mileage?
Decreased Gas Mileage When a canister purge valve doesn’t open as it should, your gas mileage might be negatively affected. The vapors in your car used in combustion will go to the EVAP canister then get vented out into the environment, causing you to use some of the fuel that your car would usually use for burning.
