Its not false info. So let me get this right. A coolant temp. sensor works different on a honda than a GM? Thats like saying a fuel pump on a honda works different than one on a GM. The temp. sensor is the sensor for the gauge on the dash, the coolant temp. sensor and the fan switch work together. I had the same problem as this guy and it ended up being the coolant temp. sensor. That is why I gave my input. And that picture is from a single cam motor. I dont know if you have noticed he has a single cam motor. Also has this guy even fixed the problem yet? I still wanna know what he has done and if it has fixed it.

coolant temp sensor is what tells the fan to turn on i believe its located by the thermostat if the fan works when u jump it thats prolly what it is

Dude that is the correct CIRCUIT DIAGRAM from the HONDA MANUAL. The picture YOU posted is not a wiring diagram. Nor do I see the part you speak of in the same circuit.

I never said it was a wiring diagram. I was proving there is a coolant temp. sensor. Which is number 13. Number 12 is the fan switch. The point isnt if there is one or not though. The point Im making is that the coolant temp. sensor could be the reason the fan isnt coming on. YES the fan switch is the obvious answer, but it may not be what is wrong. The coolant temp. sensor and the fan switch work together with the ecu. The link I provided was to explain what a coolant temp. sensor does, and yes it maybe from a GM site. But just because its from a GM doesnt mean it works different. A starter, battery, fuel pump, thermostat, radiator, brake rotor, clutch all WORK the same no matter what kind of car they are on.

Did we say there wasn't one? He jumped the switch and it worked , doesn't that tell you something?
Right those parts work the same, but they have different parts controlling them on their respective circuits. You need to listen bro, it's good for you.

He may have rigged it to work, but that doesnt solve the problem. And the listening thing should be left up to you guys. freakasis was saying the coolant temp. sensor had nothing to do with the fan switch and the fan turning on.

just stop talking, cuz your so pissed off that you might be wrong that your not even making sense anymore.

yes the sensor itself does work the same, but its the circuit that dictates what it can control. and in this case the temp sensor has nothing to do with the fan working.

everyone knows what the prob is except you. its either the thermostat not opening and thus the water not being hot enough to trip the switch. or its the switch itself. there are no other possibilities that fit with the info he has provided.

yes but his rigging had nothing to with the coolant temp sensor, so how can that be the prob? it cant be.

thats correct

Problem fixed, it was the thermostat. Freakasis was correct. And he is a good tech cause I posted different problems here and he always has good suggestions.

Thanks TR for all the help.
