Judged when the average temperature of the air intake temperature sensor (built in the air flow sensor) and
the intercooler outlet temperature sensor is 30
C {86
F} or more while the average temperature of the inter-
cooler outlet temperature sensor and the intake manifold temperature sensor is 30
C {86
F} or more.
3.
Reset condition
•
After restoration to normal condition.
