FUEL PRESSURE

8. If result is unsatisfactory, go to next step.
9. Check the following.

• Fuel hoses and fuel tubes for clogging

• Fuel filter for clogging

• Fuel pump

• Fuel pressure regulator for clogging

If OK, replace fuel pressure regulator.

If NG, repair or replace.

10. Before disconnecting Fuel Pressure Gauge and Fuel Pressure Adapter J-44321-6, release fuel pressure

to zero. Refer to "FUEL PRESSURE RELEASE".

At idling: Approximately 350 kPa (3.57 kg/cm

EVAP LEAK CHECK

How to Detect Fuel Vapor Leakage

INFOID:0000000006158958

CAUTION:

• Never use compressed air or a high pressure pump.
• Do not exceed 4.12 kPa (0.042 kg/cm

2

, 0.6 psi) of pressure in EVAP system.

NOTE:

• Do not start engine.

• Improper installation of EVAP service port adapter to the EVAP service port may cause a leak.

 WITH CONSULT-III

1. Attach the EVAP service port adapter securely to the EVAP service port.

2. Also attach the pressure pump and hose to the EVAP service port adapter.

3. Turn ignition switch ON.

4. Select the “EVAP SYSTEM CLOSE” of “WORK SUPPORT MODE” with CONSULT-III.

5. Touch “START”. A bar graph (Pressure indicating display) will appear on the screen.

6. Apply positive pressure to the EVAP system until the pressure indicator reaches the middle of the bar

graph.

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

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

EC-31, "Descrip-

tion"

.

 WITHOUT CONSULT-III

1. Attach the EVAP service port adapter securely to the EVAP ser-

vice port.

2. Also attach the pressure pump with pressure gauge to the EVAP

service port adapter.

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-31, "Description"

: Drain filter

2

: EVAP control system pressure sensor

3

:  EVAP  canister
