Evaporative emission system (EVAP) valve (%)

Measurement range: 0-100%.

The value indicates the deployment signal from the control module for deploying the evaporative emission system (EVAP) valve (the amount the valve opens to empty the canister).

0% = no control (Evaporative emission system (EVAP) valve closed).

100% = full control (Evaporative emission system (EVAP) valve opens completely).
