ACCELERATOR PEDAL RELEASED POSITION LEARNING

Description

INFOID:0000000010702861

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.

Work Procedure

INFOID:0000000010702862

1.

START

1.

Make sure that accelerator pedal is fully released.

2.

valve by monitoring the throttle position sensor output signal. It must be performed each time the harness con-
nector of the electric throttle control actuator or ECM is disconnected or electric throttle control actuator inside
is cleaned.

Work Procedure

INFOID:0000000010702864

1.
