27. Turn the ignition switch OFF.

28. Connect 2 three-way T-fittings (A) into the hose

from the EVAP canister to the EVAP two way valve.
Connect the FTP sensor to one of the T-fittings and
the vacuum pump/gauge, 0

30 in.Hg, to the other.

29. Remove the vent hose from the EVAP canister vent

shut valve (A), and cap the port (B) to seal the fresh
air vent for the EVAP canister.

30. Turn the ignition switch ON (II).

31. While monitoring FTP sensor voltage with the HDS,

or measuring voltage between ECM/PCM
connector terminals E4 and E14, slowly pump the
vacuum pump.

32. Continue to pump until the voltage drops to about

1.5 V. Make sure your vacuum pump has no leak.

33. Monitor the voltage for 20 seconds.

Inspect the EVAP canister vent shut valve

line and connections.

Go to step 34.

34. Turn the ignition switch OFF.

35. Disconnect the quick-connect fitting (A) from the

EVAP canister, and plug the canister port (B).

36. Turn the ignition switch ON (II).

37. While monitoring FTP sensor voltage with the HDS,

or measuring voltage between ECM/PCM
connector terminals E4 and E14, slowly pump the
vacuum pump.

38. Continue to pump until the voltage drops to about

1.5 V. Make sure your vacuum pump has no leak.

39. Monitor the voltage for 20 seconds.

Inspect the fuel tank vapor control line and

connections. Also test the fuel tank vapor control
valve (see page 11-469).

Go to step 40.

40. Turn the ignition switch OFF.

41. Disconnect the purge line hose (A) from the

canister at the metal line, and plug the hose (B).

42. Turn the ignition switch ON (II).

43. While monitoring FTP sensor voltage with the HDS,

or measuring voltage between ECM/PCM
connector terminals E4 and E14, slowly pump the
vacuum pump.

44. Continue to pump until the voltage drops to about

1.5 V. Make sure your vacuum pump has no leak.

45. Monitor the voltage for 20 seconds.

Inspect the EVAP canister purge valve line

and connections. If they are OK, do the EVAP two
way valve test (see page 11-468) and the fuel tank
vapor control valve test (see page 11-469).

Replace the EVAP canister (A).

EVAP System

EVAP Two Way Valve Test

07JAZ-001000B

• Vacuum/pressure gauge, 0

4 in.Hg, 07JAZ-001000B

• Vacuum pump/gauge, 0

30 in.Hg, Snap-on YA4000A

or equivalent, commercially available

1. Remove the fuel fill cap.

2. Disconnect the vapor line from the EVAP two way

valve (A). Connect the line to a T-fitting (B) from the
vacuum gauge and the vacuum pump/gauge,
0

30 in.Hg, as shown.

3. Apply vacuum slowly and continuously while

watching the gauge. The vacuum should stabilize
momentarily at 0.8

2.1 kPa (0.2

0.6 in.Hg,

16 mmHg).

If the vacuum stabilizes (valve opens) below 0.8 kPa
(0.2 in.Hg, 6 mmHg) or above 2.1 kPa (0.6 in.Hg,
16 mmHg), install a new valve and retest.

4. Move the vacuum pump hose from the vacuum

fitting to the pressure fitting, and move the vacuum
gauge hose from the vacuum side to the pressure
side (A) as shown.

5. Slowly pressurize the vapor line while watching the

gauge. The pressure should stabilize momentarily
above 1.0 kPa (0.3 in.Hg, 8 mmHg).

• If the pressure momentarily stabilizes (valve

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

• If the pressure stabilizes below 1.0 kPa (0.3 in.Hg,

8 mmHg), install a new valve and retest.

Fuel Tank Vapor Control Valve Test

Vacuum pump/gauge, 0

30 in.Hg, Snap-on YA4000A

or equivalent, commercially available

1. Make sure the fuel tank is less than half full.

2. Remove the fuel fill cap to relieve fuel tank

pressure, then reinstall the cap.

3. Disconnect the fuel tank vapor recirculation tube

(A), and connect the vacuum pump/gauge,
0

30 in.Hg, to the tube.

4. Plug the line (B).

5. Apply vacuum to the fuel tank vapor recirculation

tube.

• If the vacuum holds, replace the fuel tank vapor

control valve (see page 11-471).

• If the vacuum does not hold, the float is OK. Do

the valve test.

1. Make sure the fuel tank is less than half full.

2. Remove the fuel fill cap.

3. Disconnect the fuel tank vapor signal tube (A).

4. Disconnect the vacuum hoses (A) from the EVAP

canister (B), then plug the ports with plugs (C).

5. Disconnect the vacuum hose (D) from the EVAP

canister vent shut valve (E), and connect the
vacuum pump/gauge, 0

30 in.Hg, to the vacuum

hose.

6. Pump the vacuum pump 80 times.

• If the vacuum holds, go to step 7.
• If the vacuum does not hold, go to step 10.
