Daughter's car has the common coolant temperature fault. I think it has gone open circuit
Looking at the thermostat, I am unsure whether the sensor can be changed.
I would rather simply pop a new sensor in if possible.
It looks like it does not screw in and I don't want to force it.
I recently got a P0115 code on my Astra which is a coolant temperature sensor one.
The car had two sensors one at the radiator and one on the thermostat housing.
I decided to change them both as the cost of a sensor is about £8 and wasn't sure how to diagnose them.
It left me...
