Where is Coolant Teperature Sensor & fuse located?
I've had the Low Coolant idiot light on constantly for months. The coolant level is fine, looks fine and always has been. I'm 99% sure its just a bad coolant sensor, or maybe the fuse for the sensor?
Problem is, I can't find either one. I have a '94 3800 TPI (non supercharged) engine. The Haynes is fuzzy on where to find the sensor. Is it hiding below/behind my alternator on manifold on pass. side??) Is it near the throttle body on driver'* side?
Also, where is the fuse for this sensor? Thanks as always.

Unplugged, coolant light still on
OK, so I located wiring that plugs into the passenger side of the radiator. The wiring plugs into a housing which in turn plugs into the radiator. I unplugged the wiring but left the housing in. There was no change on the dash- all trouble lights come on when starting the car, then go off, then the 'Low Coolant' light comes back on. I'm assuming that I need to unplug the whole housing to make the dummy light go away?

the sensor is probably bad, you can replace it then plug it back in, or sounds like a short on the connector (like a paper clip, wire between the wires that go into the harness) would turn the light off.

Sensor Circuit
So you are saying, just closing the circuit will turn the light off? And connecting/jumping the two wire ends will NOT blow a fuse or worse?

sensors like that are open or closed, if you have it open( unplugged) and it thinks the coolant is low then closed( shorted together) is what is going to make it think the coolant is good. personally i would just replace the sensor. thats one of those things thats good to have if you have a leak it may save you from getting into a bad situation. when it went in my bonnie i dont remember it being that expensive.
