Checking the component

Slacken off the evaporative emission system (EVAP) valve
Connect a vacuum pump to the evaporative emission system (EVAP) valve terminal (B). Pump a vacuum. Check that there is no leakage through the evaporative emission system (EVAP) valve by listening to and checking via the pump gauge that the pressure is stable
Connect the Evaporative emission system (EVAP) valve connector
Ignition on
Activate the evaporative emission system (EVAP) valve. When the Evaporative emission system (EVAP) valve is activated, the valve opens and clicks. Check on the pump gauge that the vacuum drops (the pressure evens out) when the evaporative emission system (EVAP) valve opens.
If the function is OK, there must be no leakage when the evaporative emission system (EVAP) valve is closed (stable pressure on the pump gauge) and the vacuum must drop when the evaporative emission system (EVAP) valve opens (the pressure evens out).

The evaporative emission system (EVAP) valve is damaged if the function is faulty.

If the function of the Evaporative emission system (EVAP) valve is OK, check:
- The hose and hose terminals between the Evaporative emission system (EVAP) valve and the intake manifold. Check for leakage and blockages
- Check the hose and hose terminals between the EVAP canister and the Evaporative emission system (EVAP) valve. Check for leakage and blockages.
Remedy as necessary.
