ACCELERATOR PEDAL RELEASED POSITION LEARNING

ACCELERATOR PEDAL RELEASED POSITION LEARNING : Description

INFOID:0000000001096732

Accelerator Pedal Released Position Learning is a function of ECM to learn the fully released position of the
accelerator pedal by monitoring the accelerator pedal position sensor output signal. It must be performed each
time harness connector of accelerator pedal position sensor or ECM is disconnected.

THROTTLE VALVE CLOSED POSITION LEARNING

THROTTLE VALVE CLOSED POSITION LEARNING : Description

INFOID:0000000001096734

Throttle Valve Closed Position Learning is a function of ECM to learn the fully closed position of the throttle
valve by monitoring the throttle position sensor output signal. It must be performed each time harness connec-
tor of electric throttle control actuator or ECM is disconnected.

THROTTLE VALVE CLOSED POSITION LEARNING : Special Repair Requirement

INFOID:0000000001096735

1.

START

1.

Make sure that accelerator pedal is fully released.

2.

Turn ignition switch ON.

3.

Turn ignition switch OFF and wait at least 10 seconds.
Make sure that throttle valve moves during above 10 seconds by confirming the operating sound.

>> END

IDLE AIR VOLUME LEARNING

IDLE AIR VOLUME LEARNING : Description

INFOID:0000000001096736

Idle Air Volume Learning is a function of ECM to learn the idle air volume that keeps each engine idle speed
within the specific range. It must be performed under any of the following conditions:
• Each time electric throttle control actuator or ECM is replaced.
• Idle speed or ignition timing is out of specification.

IDLE AIR VOLUME LEARNING : Special Repair Requirement

INFOID:0000000001096737

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.
• Battery voltage: More than 12.9V (At idle)

-

Fully depress the accelerator pedal.

-

Fully release the accelerator pedal.

7.

Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the MI stops
blinking and turned ON.

8.

Fully release the accelerator pedal within 3 seconds after the MI turned ON.

9.

Start engine and let it idle.

10. Wait 20 seconds.

>> GO TO 4.

4.

CHECK IDLE SPEED AND IGNITION TIMING

Rev up the engine two or three times and make sure that idle speed and ignition timing are within the specifi-
cations.
