16. Disconnect PCM connector A (32P).
17. Check for continuity between EVAP bypass
solenoid valve 2P connector terminal No. 2 and
body ground.
Repair short in the wire between the EVAP
bypass solenoid valve and the PCM (A3).
Substitute a known-good PCM and recheck
(see page 11-5). If the symptom/indication goes
away, replace the original PCM.
18. Disconnect the vacuum hose from the EVAP
canister vent filter (A), and connect a vacuum pump
to the hose.
19. Turn the EVAP canister vent shut valve on with the
HDS, or connect PCM connector terminal A4 to
body ground with a jumper wire.
20. Turn the ignition switch ON (II)
21. Apply vacuum to the hose.
The EVAP canister vent shut valve is OK. Go
to step 27.
Go to step 22.
22. Turn the ignition switch OFF.
23. Disconnect the EVAP canister vent shut valve 2P
connector.
24. Check for continuity between EVAP canister vent
shut valve 2P connector terminal No. 2 and body
ground.
Go to step 25.
Repair open in the wire between the EVAP
canister vent shut valve and the PCM (E22).

25. Turn the ignition switch ON (II).
26. Measure voltage between EVAP canister vent shut
valve 2P connector terminal No. 1 and body ground.
Replace the EVAP canister vent shut valve
(A) and O-ring (B).
Repair open in the wire between the EVAP
canister vent shut valve and No. 6 ECU (PCM)
CRUISE CONTROL (15A) fuse.
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 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 of the EVAP canister.
30. Turn the ignition switch ON (II).
31. While monitoring FTP sensor voltage with the HDS,
or while measuring voltage between PCM
connector terminals A29 and C18, slowly pump the
vacuum pump every 1
2 seconds.
32. Continue to pump vacuum until the voltage drops
to about 1.5 V. Make sure that the engine coolant
temperature is still above 95°F (35°C) and 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 fuel tank vapor vent tube (A) from
the canister at the metal line, and plug the hose (B).
36. Turn the ignition switch ON (II).
37. While monitoring FTP sensor voltage with the HDS,
or measuring voltage between PCM connector
terminals A29 and C18, slowly pump the vacuum
pump every 1
2 seconds.
38. Continue to pump vacuum until the voltage drops
to about 1.5 V. Make sure that the engine coolant
temperature is still above 95°F (35°C) and your
vacuum pump does not have a leak.
39. Monitor the voltage for 20 seconds.
Check the fuel tank vapor control line and
connections for misrouting, poor connections,
damage, or pinched areas. If the line and
connections are OK, replace the fuel tank vapor
control valve.
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 while measuring voltage between PCM
connector terminals A29 and C18, slowly pump the
vacuum pump every 1
2 seconds.
44. Continue to pump vacuum until the voltage drops
to about 1.5 V. Make sure that the engine coolant
temperature is still above 95°F (35°C) and your
vacuum pump does not have a leak.
45.
Inspect the EVAP canister purge valve line
and connections. If they are OK, do the EVAP two
way valve test (see page 11-297). It the line, the
connections, and the EVAP two way valve are OK,
replace the EVAP canister purge valve.
Replace the EVAP canister.

• Vacuum/pressure gauge, 0

1. Remove the fuel fill cap.
2. Disconnect the vapor line from the EVAP two way
valve (A), and connect it to a T-fitting (B) from the
vacuum gauge and the 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 (0.2
0.6 in.Hg, 6
16
mmHg).
If the vacuum stabilizes (valve opens) below 0.8 kPa
(0.2 in.Hg, 0.6 mm Hg) 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 mm Hg).
• 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.
