THROTTLE VALVE POSITION LEARNING

Description

INFOID:0000000010935601

Throttle valve position learning is an operation to learn the fully closed position of the throttle valve by monitor-
ing the throttle position sensor output signal. It must be performed each time harness connector of electric
throttle control actuator or ECM is disconnected.
• Electric throttle control actuator is removed.
• Electric throttle control actuator is replaced.
• ECM is replaced.

NOTE:
The necessary operation is different depending on the operation result of ECM data save or write. Always
perform the operation according to procedures. Refer to 

EC-944, "Work Procedure"

.

Work Procedure

Description

INFOID:0000000010935603

Exhaust throttle valve position learning is an operation to learn the fully closed position of the exhaust throttle
valve. It must be performed each time harness connector of exhaust electric throttle control actuator or ECM is
disconnected.
• Exhaust electric throttle control actuator is removed.
• Exhaust electric throttle control actuator is replaced.
• ECM is replaced.

NOTE:
The necessary operation is different depending on the operation result of ECM data save or write. Always
perform the operation according to procedures. Refer to 

EC-944, "Work Procedure"

.

EGR VOLUME CONTROL VALVE POSITION LEARNING

Description

INFOID:0000000010935605

EGR volume control valve position learning is an operation to learn the fully closed position of the high pres-
sure EGR volume control valve by monitoring the high pressure EGR volume control valve position sensor
output signal. It must be performed under any of the following conditions:
• High pressure EGR volume control valve is removed.
• High pressure EGR volume control valve is replaced.
• ECM is replaced.

NOTE:
The necessary operation is different depending on the operation result of ECM data save or write. Always
perform the operation according to procedures. Refer to 

EC-944, "Work Procedure"

.

Work Procedure

INFOID:0000000010935606

1.

START

1.

Turn ignition switch OFF and wait at least 10 seconds.

2.

Turn ignition switch ON and wait for 1 minute.
NOTE:
Check that high pressure EGR volume control valve moves by confirming the operating sound.

LOW PRESSURE EGR VOLUME CONTROL VALVE POSITION LEARNING

LOW PRESSURE EGR VOLUME CONTROL VALVE POSITION LEARNING

Description

INFOID:0000000010935607

Low pressure EGR volume control valve position learning is an operation to learn the fully closed position of
the low pressure EGR volume control valve by monitoring the low pressure EGR volume control valve position
sensor output signal. It must be performed under any of the following conditions:
• Low pressure EGR volume control valve is removed.
• Low pressure EGR volume control valve is replaced.
• ECM is replaced.

NOTE:
The necessary operation is different depending on the operation result of ECM data save or write. Always
perform the operation according to procedures. Refer to 

EC-944, "Work Procedure"

.

Work Procedure

INFOID:0000000010935608

1.

START

1.

Turn ignition switch OFF and wait at least 10 seconds.

2.

Turn ignition switch ON and wait for 1 minute.
NOTE:
Check that low pressure EGR volume control valve moves by confirming the operating sound.
