DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE
Is 1st trip DTC detected? YES >> Proceed to EC-180, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE POWER SUPPLY
Is the inspection result normal? YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE POWER SUPPLY CIRCUIT
Is the inspection result normal? YES >> Perform the trouble diagnosis for power supply circuit.
NO >> Repair or replace error-detected parts.
3.CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE GROUND CIRCUIT
Is the inspection result normal? YES >> GO TO 4.
NO >> Repair or replace error-detected parts.
4.CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE
Check the intake valve timing control solenoid valve. Refer to EC-181, "Component Inspection (IVT Control Solenoid Valve)".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Replace intake valve timing control solenoid valve. Refer to EM-48, "Exploded View".
Component Inspection (IVT Control Solenoid Valve)
1.CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-1
Is the inspection result normal? YES >> GO TO 2.
NO >> Replace intake valve timing control solenoid valve. Refer to EM-48, "Exploded View".
2.CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-2
CAUTION:
Do not apply 12 V DC continuously for 5 seconds or more.
Doing so may result in damage to the coil in intake valve timing control solenoid valve.
NOTE:
Always replace O-ring when intake valve timing control solenoid valve is removed.
Is the inspection result normal? YES >> INSPECTION END
NO >> Replace intake valve timing control solenoid valve. Refer to EM-48, "Exploded View".
P0506 ISC System
Description
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 ...
