ON-VEHICLE INSPECTION
PROCEDURE
1. INSPECT INTAKE SYSTEM
HINT:
Perform "Inspection After Repair" after repairing vacuum leaks in the intake
system (See page ).
(a) Check that there are no vacuum leaks at the points shown in the illustration.
2. PERFORM INITIALIZATION
(a) Perform "Inspection After Repair" after repairing vacuum leaks in the intake
system (See page ).
3. INSPECT INTAKE AIR CONTROL VALVE (for ACIS)
(a) Connect the Techstream to the DLC3.
(b) Start the engine and turn the Techstream on.
(c) Warm up the engine.
(d) Enter the following menus: Powertrain / Engine and ECT / Active Test / Activate the VSV for Intake Control. |
|
(e) When "Activate the VSV for Intake Control" is turned on, check that the actuator rod operates.
If the operation is not as specified, inspect the intake air control valve, vacuum
tank and check valve (See page ).
(f) When "Activate the VSV for Intake Control" is turned off, check that the actuator rod returns to its original position.
If the operation is not as specified, inspect the intake air control valve and
vacuum hose (See page ).
4. INSPECT INTAKE AIR CONTROL VALVE ACTUATOR (for TCV)
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON (do not run the engine).
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine and ECT / Active Test / All Data / Control the IAC Duty Ratio.
(1) Set the duty ratio to 60% or -60% for 1 to 3 seconds, and then return the duty ratio to 0%. Check Intake Air Control Position in the Data List.
Specified Condition:
Condition (Active Test) |
Specified Condition (Data List) |
---|---|
Control the IAC Duty Ratio set to 60% |
Intake Air Control Position 35° or more |
Control the IAC Duty Ratio set to -60% |
Intake Air Control Position 17° or less |
NOTICE:
HINT:
The standard duty ratio for inspections is 60% or -60%. However, if the value in the Data List is not as specified, set the duty ratio to 100% or -100% for 1 to 3 seconds, and check the value in the Data List again.
(e) When the result is not as specified during the Active Test, perform the following procedure.
(1) Remove the intake manifold (See page ).
HINT:
When removing the intake manifold, the tumble control valves are half open.
(2) Check that the valves move when connecting the battery to the terminals of the intake air control valve actuator.
Standard:
Tester Connection |
Specified Condition |
---|---|
Positive (+) battery voltage applied to terminal 4 (M-), and negative (-) battery voltage applied to terminal 5 (M+) |
Open → Closed |
Positive (+) battery voltage applied to terminal 5 (M+), and negative (-) battery voltage applied to terminal 4 (M-) |
Closed → Open |
NOTICE:
(3) When the results are not as specified, perform the following inspections.
Check that the valves are not cracked or deformed.
Remove the intake air control actuator, and check that the valves move smoothly.
If there are no problems with the valves, inspect the intake air control valve
actuator (See page ).

(a) Apply a light coat of gasoline or spindle oil to new O-rings, and
then ...
If your vehicle overheats
The following may indicate that your vehicle is overheating.
• The engine coolant temperature gauge reaches the maximum, or a loss of
engine power is experienced. (For example, the vehicle speed does not increase.)
• Steam comes out from under the hood ...
