Coolant Temp sensor the one which provide signal for ECU to activate/control fan speed, dashboard gauge and also input data fuel ratio.
However, coolant temperature is control by thermostat and temperature sensor.
thermostat will stay close to heat up the engine and open @ 89deg to allow coolant to flow thru radiator for cooling.
If coolant temperature sensor is faulty, it cant provide accurate signal to ECU to activate fan in time, causing engine to heat up.
Got error code P101, so i googled, it was temperature sensor error. Upstream pipe radiator is very hot, so i suspected the thermostat not open. Consulted my friend mechanic, who specialises in contis, he told me to change the whole thermostat assembly.
First weekend DIY project on my 408thp lol. Still waiting for parts from China. Wish me luck.
Why diy? Workshop quoted me 1k, 900 and lowest 864. When i google for parts, can get as low as 250, or in lazada i found 128:
