I have a code P0118. From what I found on line it leads to a faulty Engine Coolant Temp Sensor. I cannot figure out where it is located. There's a few sensors I suspect, but I was hoping you'd be able to provide a picture. Or if you have anything else I should be checking too. Also, I'm not too sure if my fan is turning on. It works when the AC is on, but I let it idle for 15-20min w/o the AC and it doesn't turn on. Any ideas? Thanks.
