coolant temp sensor?

[NCjeeper]

does anyone know where the "engine coolant temp sensor" goes? "circuit high input" i threw a check gauge and this came up on the obd-II test. could this be causing my auxiliary fan to not come on? im having that problem as well.

okay i got the sensor. the only place i saw that it would go was the thermostat housing... so i replaced it, went by advance, and it showed up on the test again. still having the problem. any ideas? im also showing an o2 sensor is bad in the exhaust.

Which o2 sensor?? I'm a TJ owner so it might not be the same............had the same problems myself. My fourbanger has 2 - one up in the engine compartment just below the manifold (sensor 1/bank 1) and another underneath, just in front of the cat/muffler (sensor 2/bank 1 maybe????? - never threw a code for that one).

yeah, see, the same wiring that runs to the thermo housing temp. sensor come from the fuel rail, splits and also runs down the side of the block to the o2 sensor on the exhaust. auxiliary fan still isnt coming on at all. overheating. NEED HELP!

Man, that sucks! Sorry I can't help you............my wiring is much simpler. Gotta love the 4bangers!
