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.

Inspection procedure
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.
Data list / active test (2006/01- )
Read data list
Hint:
Using the intelligent tester's data list allows switch,
sensor, actuator and other item values to be read without
removing any parts. Reading the data list early in
troubleshooting is one way to save time.
Connect the intelligent tester (with can vim) to the
