1.

Visually inspect EVAP vapor lines for improper attachment and for cracks, damage, loose connections,
chafing and deterioration.

2.

Check EVAP canister as follows:

a.

Block port (B). Orally blow air through port (A).
Check that air flows freely through port (C).

b.

Block port. Orally blow air through port.

resistance should be felt and a portion of air flow should be
directed toward the EVAP canister side.

b.

Blow air through connector on EVAP canister side. Air flow
should be smoothly directed toward fuel tank side.

c.

If fuel check valve is suspected or not properly functioning in
step 1 and 2 above, replace it.

5.

Inspect fuel tank filler cap vacuum relief valve for clogging, stick-
ing, etc.

a.

Wipe clean valve housing.
