P0506 ISC SYSTEM
Description INFOID:0000000004780224
The ECM controls the engine idle speed to a specified leve l through the fine adjustment of the air, which is let
into the intake manifold, by operating the electric thrott le control actuator. The operating of the throttle valve is
varied to allow for optimum control of the engine idli ng speed. The crankshaft position sensor (POS) detects
the actual engine speed and sends a signal to the ECM.
The ECM controls the electric throttle control actuator so that the engine speed coincides with the target value
memorized in the ECM. The target engine speed is t he lowest speed at which the engine can operate steadily.
The optimum value stored in the ECM is determined by taking into consideration various engine conditions,
such as during warming up, deceleration, and engine load (air conditioner, power steering and cooling fan
operation, etc.).
DTC Logic INFOID:0000000004780225
DTC DETECTION LOGIC NOTE:
If DTC P0506 is displayed with ot her DTC, first perform the trouble diagnosis for the other DTC.
DTC CONFIRMATION PROCEDURE IDLE AIR VOLUME LEARNING :
Special Repair Requirement " , before conducting DTC Confirmation Procedure.
TESTING CONDITION:
• Before performing the following procedure, confirm that battery voltage is more than 11 V at idle.
• Always perform the test at a temperature above −10 °C(14 °F).
>> GO TO 2. YES >> Go to
EC-349, " Diagnosis Procedure " .
NO >> INSPECTION END

DTC Confirmation Procedure INFOID:0000000004537084
CAUTION:
Always drive at a safe speed.
NOTE:
• If DTC P0011 is displayed with DTC P0075, first perform trouble diagnosis for DTC P0075.
See EC-650 .
• If DTC Confirmation Procedure has been previously conduc ted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confi rm that battery voltage is between 10V and 16V at
idle.
WITH CONSULT-III
1. Turn ignition switch ON and select “DATA MONITOR” mode with CONSULT-III.
2. Start engine and warm it up to the normal operating temperature.
3. Maintain the following conditions for at least 6 consecutive seconds. Hold the accelerator pedal as steady as possible.
4. Let engine idle for 10 seconds.
5. Check 1st trip DTC. If 1st trip DTC is detected, go to EC-638, " Diagnosis Procedure " .
If 1st trip DTC is not detected, go to next step.
6. Maintain the following conditions for at least 20 consecutive seconds.
