Outline Of Diagnosis

Detect the malfunction of the engine coolant temperature sensor 2 characteristics.

After the engine starts for the first time after the specified period of soaking time has elapsed, diagnose by correlation between engine coolant temperature sensor 1 value, engine coolant temperature sensor 2 value and engine oil temperature sensor value.

Judge as NG when the differences are both above the specified value by comparing between engine coolant temperature 1 and engine coolant temperature 2, engine coolant temperature 2 and engine oil temperature.
