AIR INTAKE ACTUATOR INSPECTION

id074000701400

Actuator inspection

1.  Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

2.  Remove the air intake actuator. (See AIR INTAKE ACTUATOR REMOVAL/INSTALLATION.)

3.  Connect the air intake actuator connector.

4.  Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

5.  Switch the ignition ON (engine off or on).

6.  Connect the M-MDS to the DLC-2.

7.  Operate the air intake actuator using the simulation function [INTAKE_ACTAT_MODE] of the dash-electrical supply unit. (See SIMULATION INSPECTION)(See SIMULATION TABLE [DASH-ELECTRICAL SUPPLY UNIT].)

8.  Verify that the air intake actuator operation condition is as shown in the figure.

Caution

•  If the lever position exceeds the operation range shown in the figure, the circuit in the actuator could be damaged. Always perform an actuator operation inspection with the lever movement within the range shown in the figure.

9.  If it does not operate as shown in the figure, replace the air intake actuator. (See AIR INTAKE ACTUATOR REMOVAL/INSTALLATION.)

Position sensor inspection

1.  Connect the M-MDS to the DLC-2.

2.  Switch the ignition ON (engine on).

3.  Display PID [INTAKE_ACTAT_POS] using the M-MDS. (See PID/DATA MONITOR INSPECTION.)(See PID/DATA MONITOR TABLE [DASH-ELECTRICAL SUPPLY UNIT].)

4.  Operate the REC switch.

5.  Verify that the PID value switches according to the REC switch operation.

6.  If the PID value does not switch, replace the air intake actuator. (See AIR INTAKE ACTUATOR REMOVAL/INSTALLATION.)
