Inspection

INSPECTION

PROCEDURE

1. INSPECT INTAKE AIR CONTROL VALVE ACTUATOR (for TCV)

(a) Check the intake air control valve actuator operation.

(1) Check that the motor operates when the battery is connected to the terminals of the intake air control valve actuator.

NOTICE:

If the positive (+) and negative (-) battery leads contact the sensor terminals, the actuator may be damaged.

Standard:

Tester Connection

Specified Condition

Positive (+) battery voltage applied to terminal 4 (M-), and negative (-) battery voltage applied to terminal 5 (M+)

Motor rotates clockwise

Positive (+) battery voltage applied to terminal 5 (M+), and negative (-) battery voltage applied to terminal 4 (M-)

Motor rotates counterclockwise

If the result is not as specified, replace the intake air control valve actuator.


Installation

INSTALLATION

PROCEDURE

1. INSTALL INTAKE AIR CONTROL VALVE ACTUATOR (for TCV)

NOTICE:

  • Make sure that foreign matter, such as water, oil, sand and iron particles, does not enter the gear chamber or actuator at the locations marked by the circles in the illustration.

  • Do not loosen or remove the bolt and 2 nuts shown in the illustration.

(a) Close the tumble control valves.

HINT:

If the tumble control valves are not closed, close them by hand.
