THROTTLE VALVE CLOSED POSITION LEARNING
Description
INFOID:0000000010379047
Throttle Valve Closed Position Learning is an operation to learn the fully closed position of the throttle valve by
monitoring the throttle position sensor output signal. It must be performed under the following conditions:
• Electric throttle control actuator is removed.
• Electric throttle control actuator is replaced.
• ECM is replaced.
• Battery is replaced.
Work Procedure
INFOID:0000000010379048
1.
PRECONDITIONING
Make sure that all of the following conditions are satisfied.
Learning will be cancelled if any of the following conditions are missed for even a moment.
• Make sure that no DTC is displayed with CONSULT.
• Engine stopped
• Accelerator pedal: Fully released
• Battery voltage: More than 10 V
• Intake air temperature: 5 - 90
°
C (41 - 194
°
F)
• Vehicle speed: Stopped
>> GO TO 2.
2.
PERFORM THROTTLE VALVE CLOSED POSITION LEARNING
1.
Turn ignition switch ON and wait at least 5 seconds. Make sure that throttle valve moves during above 5
seconds by confirming the operating sound.
2.
Turn ignition switch OFF and wait at least 12 minutes.
