FUEL CUT CONTROL (AT NO LOAD AND HIGH ENGINE SPEED)
If the engine speed is above 2,000 rpm under no load (for ex
ample, the selector lever position is neutral and
engine speed is over 2,000 rpm) fuel will be cut off after some time. The exact time when the fuel is cut off var-
ies based on engine speed.
Fuel cut will be operated until the engine speed reaches 1,500 rpm, then fuel cut will be cancelled.
NOTE:
This function is different from deceleration contro l listed under Multiport Fuel Injection (MFI) System, EC-43,
"MULTIPORT FUEL INJECTION SYSTEM : System Description (w ith automatic air conditioner)" or EC-46,
"MULTIPORT FUEL INJECTION SYSTEM : System Description (with manual air conditioner)".

1.CHECK EVAP CANISTER
1. Block port (B).
2. Blow air into port (A) and check that it flows freely out of port (C).
3. Release blocked port (B).
4. Apply vacuum pressure to port (B) and check that vacuum pres-
sure exists at the ports (A) and (C).
5. Block port (A) and (B).
6. Apply pressure to port (C) and check that there is no leakage.

EVAP LEAK CHECK
InspectionINFOID:0000000009462466
CAUTION:
• Do not 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 [commercial service tool: (J-41413-OBD)] to the EVAP
service port may cause a leak.
1.EVAP LEAK CHECK
With CONSULT
1. Install EVAP service port adapter [commercial service tool: (J- 41413-OBD)] and pressure pump to EVAP service port.
2. Turn ignition switch ON.
3. Select the “EVAP SYSTEM CLOSE” in “WOR K SUPPORT” mode of “ENGINE” using CONSULT.
4. Touch “START”. A bar graph (Pressure indicating display) will appear on the screen.
5. Apply positive pressure to the EVAP system until t he pressure indicator reaches the middle of the bar
graph.
6. Remove EVAP service port adapter [commercial service tool: (J-41413-OBD)] and hose with pressure
pump.
7. Locate the leak using a leak detector [commercial service tool: (J-41416)]. Refer to EC-62, "EVAPORATIVE EMISSION SYS-
TEM : System Description".
Without CONSULT
1. Install EVAP service port adapter [commercial service tool: (J- 41413-OBD)] and pressure pump to EVAP service port.

EVAP LEAK CHECK
2. Apply battery voltage between the terminals of EVAP
canister vent control valve to make a closed EVAP
system.
3. 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).
4. Remove EVAP service port adapter [commercial service tool: (J-41413-OBD)] and hose with pressure
pump.
5. Locate the leak using a leak detector [commercial service tool: (J-41416)]. Refer to EC-62, "EVAPORATIVE EMISSION SYS-
TEM : System Description".

1.CHECK PCV VALVE
With engine running at idle, remove PCV valve from rocker cover. A
properly working valve makes a hissing noise as air passes through
it. A strong vacuum should be felt immediately when a finger is
placed over valve inlet.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Replace PCV valve. Refer to EC-21,
"Component Parts Location".
