ECTS Circuit And Output Features
The measure at sensor malfunction is to take the initial intake air temperature as basic substitution value of coolant temperature and increase it up to max. 110°C in the interval of 0.5 sec in response to the quantity of air.
In case of the intake air temperature sensor malfunction, first take the substitution value of coolant temperature at 20°C and increase it up to 110°C in the interval of 0.5 second by the air quantity.
In case of intake air temperature sensor malfunction during engine running, first determine a proper temperature before first finding the trouble cause, and then increase it up to 110°C in the interval of 0.5 second by the air quantity.
