Ported Applications With EVAP Service Port

1. Connect the [1][2]EVAP diagnostic cart J 41413 (1) to the vehicle EVAP service port. Turn the four position switch to Purge.
2. Start the engine. Allow the engine to reach the operating temperature.
3. Open the throttle until the engine speed reaches 2000 RPM.
4. Note the H2O vacuum gauge (6) on the [1][2]EVAP cart. The vacuum should read greater than 15 in H2O.
