DTC P0505 Idle Control System Malfunction
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 are met:
Example: If the actual idling speed varies from the target idling speed by more than 200 rpm* 5 times in a drive cycle, the ECM illuminates the MIL and sets the DTC.
*: Threshold idling speed varies according to the engine load.

INSPECTION PROCEDURE
HINT:
(b)The accelerator pedal being not fully released.
1 CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0505)
Result
HINT: If any DTCs other than P0505 are output, troubleshoot those DTCs first.
2 CHECK PCV HOSE CONNECTIONS
OK: PCV hose is connected correctly and is not damaged.
3 CHECK INTAKE SYSTEM
OK: No leakage from intake system.
4 CHECK THROTTLE VALVE
OK: No foreign objects between the throttle valve and housing.
