I'm worried that means the radiator fans won't switch on?

I went to check what codes it had, and the engine light just flashed without any pause. What could that mean?

Yeah, the temperature gauge doesn't work all that well, constantly reads as just above cold. I'm worried that means the radiator fans won't switch on.

Yep, I would replace the engine coolant sensor which should fix the gauge and allow the cooling fans to come on. Here is the location of the sensor below. Please let us know what happens.

Okay, so, I replaced the coolant temperature sensor, and it made it a little better, but the temperature gauge is still sitting low (just above cold) and I'm wondering if I need to replace the thermostat, your input would be much appreciated.
