fuel level sensor does not change. If ECM senses sloshing signal from the sensor, fuel level sensor malfunc-
tion is detected.

P0506 ISC SYSTEM
P0506 ISC SYSTEM
Description
INFOID:0000000007577211
The ECM controls the engine idle speed to a specified level through the fine adjustment of the air, which is let
into the intake manifold, by operating the electric throttle control actuator. The operating of the throttle valve is
varied to allow for optimum control of the engine idling 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 the 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.).

P0507 ISC SYSTEM
P0507 ISC SYSTEM
Description
INFOID:0000000007577214
The ECM controls the engine idle speed to a specified level through the fine adjustment of the air, which is let
into the intake manifold, by operating the electric throttle control actuator. The operating of the throttle valve is
varied to allow for optimum control of the engine idling 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 the 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.).

PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure
before conducting the next test.
1.
Turn ignition switch OFF and wait at least 10 seconds.
2.
Turn ignition switch ON.
3.
Turn ignition switch OFF and wait at least 10 seconds.
If the target idle speed is out of the specified value, perform
, before con-
ducting 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).

P050A, P050E COLD START CONTROL
Description
INFOID:0000000007577217
ECM controls ignition timing and engine idle speed when engine is started with pre-warming up condition.
This control promotes the activation of three way catalyst by heating the catalyst and reduces emissions.

Cold start idle air control system
performance
ECM does not control engine idle speed properly
when engine is started with pre-warming up con-
dition.
• Lack of intake air volume
• Fuel injection system
• ECM
