Hello TTI,
I recently found out my sensor isn't working.
I know the relay and fan work.
Having trouble removing the sensor.
I decided to just make it so the fan is always on.
Will this cause any issues?

    It will not be great come winter when your car is trying to warm up to operating temp, and may cause a decrease in fuel economy year round.  The ecu uses the coolant temp in it's calculations for how much fuel is needed, and may result in running rich all the time with that sensor data missing.  I'd recommend a proper fix.  Is it not throwing a CEL?
