EVAP LEAK CHECK

3. Apply battery voltage between the terminals of EVAP canister vent control valve to make a closed EVAP

system.

4. To locate the leak, deliver positive pressure to the EVAP system until pressure gauge points reach 1.38 to

2.76 kPa (0.014 to 0.028 kg/cm

2

, 0.2 to 0.4 psi).

5. Remove EVAP service port adapter and hose with pressure pump.

6. Locate the leak using a leak detector. Refer to

EC-37, "Description"

.

Component Inspection

INFOID:0000000005149510

EVAP CANISTER

Check EVAP canister as follows:
1. Block port B.
2. Blow air into port Aand check that it flows freely out of port C.
3. Release blocked port B.
4. Apply vacuum pressure to port B and check that vacuum pres-

sure exists at the ports Aand C.

5. Block port Aand B.
6. Apply pressure to port C and check that there is no leakage.
