Description
The idling speed is controlled by the etcs (electronic throttle control system). The etcs is comprised of: 1) the one valve type throttle body; 2) the throttle actuator, which operates the throttle valve; 3) the throttle position (tp) sensor, which detects the opening angle of the throttle valve; 4) the accelerator pedal position (app) sensor, which detects the accelerator pedal position; and 5) the ecm, which controls the etcs. Based on the target idling speed, the ecm controls the throttle actuator to provide the proper throttle valve opening angle.
Monitor description
The ecm monitors the idling speed and idling air flow volume to conduct idle speed control (isc). The ecm determines that the isc system is malfunctioning if the following conditions apply:
Example: if the actual idling speed varies from the target idling speed by more than 200 rpm* 5 times during a drive cycle, the ecm illuminates the mil and sets the dtc.
Hint:
*: Threshold idling speed varies with engine load.

Hint:
Hint:
If any dtcs other than p0505 are output, troubleshoot those dtcs first.
Ok: pcv hose is connected correctly and is not damaged.
Ok:
no leakage from air induction system.
Ok: throttle valve is not contamainated with foreign objects and moves smoothly.
Different diameter tire malfunction
Description
The skid control ecu measures the speed of each wheel by receiving signals
from the speed sensor.
These signals are used for recognizing that all 4 wheels are operating properly.
Therefore, all wheel
signals must be equal.
Inspection procedure

Correct driving posture
Adjust the angle of the seatback
so that you are sitting
straight up and so that you do
not have to lean forward to
steer.
Adjust the seat so that you can
depress the pedals fully and so
that your arms bend slightly at
the elbow when gripping the
steering wheel.
