Circuit Description

For circuit description, see DTC P0115: ENGINE COOLANT TEMPERATURE CIRCUIT MALFUNCTION . Detecting conditions of DTC are:

• When engine starts, water temperature is 20°F (-7°C) or less. And 20 minutes or more after engine starts, engine coolant temperature sensor value is 68°F (20°C) or less (2 trip detection logic).
• When engine starts, water temperature is between 20°F (-7°C) and 50°F (10°C). And 5 minutes or more after engine starts, engine coolant temperature sensor value is 68°F (20°C) or less (2 trip detection logic).
