8. Apply vacuum (1 pump) to the fuel tank vapor sig-

nal tube, then check the vacuum on the pump in

step 6.

• If the vacuum holds, replace the Fuel Tank Vapor

Control valve.

• If the vacuum is released, the Fuel Tank Vapor

Control valve is OK.

9. Disconnect the fuel tank vapor vent tube from the

EVAP canister, then plug the port on the canister.
Reapply vacuum (80 pumps).
• If the vacuum holds, replace the Fuel Tank Vapor

Control valve.

• If the vacuum does not hold, inspect the EVAP

canister vent shut valve O-ring. If the 0-ring is
OK, replace the EVAP canister and repeat step 4.

Evaporative Emission (EVAP) Two Way Valve Testing

1. Remove the fuel fill cap.

2. Remove the vapor line from the EVAP two way

valve (located above the EVAP canister), and con-

nect it to a T-fitting from a vacuum gauge and a

vacuum pump as shown.

3. Apply vacuum slowly and continuously while

watching the gauge. The vacuum should stabilize

momentarily at 0.8 - 2.1 kPa (6 - 16 mmHg, 0.2 - 0.6
in.Hg).
• If the vacuum stabilizes (valve opens) below

0.8 kPa (6 mmHg, 0.2 in.Hg) or above 2.1 kPa
(16 mmHg, 0.6 in.Hg), install a new valve and

retest.

4. Move the vacuum pump hose from the vacuum fit-

ting to the pressure fitting, and move the vacuum

gauge hose from the vacuum side to the pressure
side as shown.

5. Slowly pressurize the vapor line while watching the

gauge. The pressure should be stabilize momentarily
above 1.0 kPa (8 mmHg, 0.3 in.Hg).
• If the pressure momentarily stabilizes (valve

opens) above 1.0 kPa (8 mmHg, 0.3 in.Hg), the
valve is OK.

• If the pressure stabilizes below 1.0 kPa (8 mmHg,

0.3 in.Hg), install a new valve and retest.
