2GR-FE Intake

2GR-FE INTAKE: INTAKE SYSTEM: ON-VEHICLE INSPECTION

1. INSPECT INTAKE AIR CONTROL VALVE ASSEMBLY

(a) Inspection procedure when using the Techstream.

(1) Warm up the engine.

(2) Stop the engine.

(3) Connect the Techstream to the DLC3.

(4) Turn the ignition switch to ON.

(5) Turn the Techstream ON.

(6) Enter the following menus: Powertrain / Engine and ECT / Active Test / Activate the VSV for Intake Control.

(7) Make sure that a clicking sound is heard from the intake air control valve when current flows. If the result is not as specified, replace the intake air surge tank.





(b) Inspection procedure when applying voltage between the terminals.





(1) Disconnect the connector from the intake air control valve.

(2) Apply battery voltage between terminals 1 (-) and 2 (+) of the intake air control valve. Check that a clicking sound is heard from the intake air control valve.

If the result is not as specified, replace the intake air surge tank.

2. INSPECT VACUUM SWITCHING VALVE

(a) Perform the Active Test to operate the VSV .

3. INSPECT AIR CLEANER ASSEMBLY

(a) Inspect the actuator.

(1) Apply 80 kPa (600 mmHg, 23.6 in. Hg) of vacuum to the actuator. Check if the valve rotates open, as shown in the illustration.





(2) Apply the vacuum for 1 minute. The actuator should continue to keep the valve open.

If the result is not as specified, replace the air cleaner case assembly.

(b) Inspect the vacuum tank.

(1) Connect the vacuum pump to port A.





(2) Apply a vacuum of 66.7 kPa (500 mmHg, 20 in. Hg) to the vacuum tank.

(3) 1 minute after applying the vacuum, check that the pressure does not change.

(c) Check that there is no ventilation when pressure is applied to port B, and that there is ventilation when a vacuum is applied to port B.

If the result is not as specified, replace the air cleaner cap assembly.

4. INSPECT VACUUM SWITCHING VALVE

(a) Check the resistance of the VSV.





Standard resistance:





If the result is not as specified, replace the VSV.

(b) Check VSV operation.





(1) Check that air flows from port E to the filter.

(2) Apply battery voltage across the terminals. Check that air flows from port E to port F.





If the result is not as specified, replace the VSV.
