WARNING: This page is about a different variant/trim than selected.

NOTE: The engine coolant temperature (ECT) sensor is mounted on the engine and the radiator coolant temperature (RCT) sensor is mounted on the radiator.

As the thermostat opens, the radiator coolant temperature sensor signal should rise steadily, then stabilize once the thermostat opens completely.
Inspect for the correct operation of the engine cooling system and verify the correct coolant level.
