DTC P0505 Idle Control System Malfunction


DESCRIPTION

The idling speed is controlled by the electronic throttle control system. The electronic throttle control system is comprised of: 1) the one valve type throttle body; 2) the throttle actuator, which operates the throttle valve; 3) the throttle position sensor, which detects the opening angle of the throttle valve; 4) the accelerator pedal position sensor, which detects the accelerator pedal position; and 5) the ECM, which controls the electronic throttle control system. Based on the target idling speed, the ECM controls the throttle actuator to provide the proper throttle valve opening angle.

DTC No.

  4. ECM

INSPECTION PROCEDURE

УКАЗАНИЕ:
  1. The following condition may also cause DTC P0505 to be set:
    1. The throttle valve is not fully closed. (e.g. The accelerator pedal is slightly depressed by something such as a floor carpet overlapping the accelerator pedal.)
  2. Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
1.CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0505)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch on (IG) and turn the tester on.

  1. Select the following menu items: Powertrain / Engine and ECT / DTC.

  1. Read the DTCs.

    Result:

    Result
    		Proceed to
    DTC P0505 is output
    		A
    DTC P0505 and other DTCs are output
    		B
    УКАЗАНИЕ:
    If any DTCs other than P0505 are output, troubleshoot those DTCs first.

2.CHECK PCV HOSE CONNECTIONS

  1. Check for PCV hose connection (See page Нажмите здесь).

OK:
PCV hose is connected correctly and is not damaged.


NG
REPAIR OR REPLACE PCV HOSE
OK


3.CHECK INTAKE SYSTEM

  1. Check the intake system for vacuum leakage (See page Нажмите здесь).

    OK:
    No leakage from intake system.


NG
REPAIR OR REPLACE INTAKE SYSTEM
OK


4.CHECK THROTTLE VALVE

  1. Check the throttle valve condition (See page Нажмите здесь).

    OK:
    Throttle valve is not contaminated with foreign objects and moves smoothly.


NG
