This one?

all i can see has only 3 sensors 2of3 is after run sensor,MFTS and last one is
at the back of block see in da pic.
May be my car didn't has that kinda sensor.
All i can see is the rubber hose at the back go to the after running pump.no any sensor.

Heater hose is being cutted off.So i really didn't know where is it come from.mostly the European car that being sold in Thailand after running for 2-3 years the heater system will be cutted off.Because the weather in Thailand around 35C. further more to protect the risk that water coolant leak from the bad heater core.

This is the coolant temperature sensor used by the ECU

If you temporarily unplug the connector, the ECU will use 80C as a constant value. It will probably also set a fault code.

You could rule out the fake cold start possibility by unplugging the connector and driving around for a while.
