GI-41, "Intermittent Incident"

.

5.

CHECK INTAKE MANIFOLD RUNNER CONTROL VALVE FITTING CONDITION

Check intake manifold runner control valve fitting condition.
Is the inspection result normal?

YES

>> Check intermittent incident. Refer to 

GI-41, "Intermittent Incident"

.

NO

>> Repair or replace error-detected parts.
