What's up, new here because of this issue. This thing has been breaking every time I ride it this summer. I just got finished replacing the final gear/rear diff., axles, fixed two current draws, and I replaced the exhaust. To replace the exhaust, I took the seat and the framing for the seats out, and I think it's related.

CURRENT ISSUE: As soon as I start the machine, the check engine light begins flashing, and it's telling me that it's overheating. I know it's not overheating within a second; it's just impossible, even if it is 95+ and 100% humidity. I did have to unplug the temperature sensor right beside the spark plug and remove that entire harness, to remove the seat framing and stuff. I don't see any broken wires or anything. I am an automotive technician, but I have no resources with this machine, no wiring diagrams or tech information. Can anyone point me in the right direction or help me to test the sensor? Does it work like an old two-wire temp sensor on a car/truck? Or is it completely different? It's only a two wire sensor. Please Help. I'm trying to get rid of this thing, because it's a money pit, but I want to make sure everything is copasetic, before I sell it.

Howdy and welcome from Northern Iowa
.
For any forum, year, make and model would help us help you.
Here is a link to a 2105 Service Manual, should help with your troubleshooting.
.
First best guess, is that you bent, possibly broke, one of the sensor pins when you plugged it back in.
Unplug it and look inside.
.
Have a good day

2017 Pioneer 500. Could really use some help on this guys. I've checked the wiring, visually. I haven't tested the wires for continuity, but I don't see where any of them have been pinched or rubbed or anything.
SYMPTOM: As soon as I turn the key to the on position, the fan immediately kicks on high, the overheating light comes on, and the check engine light begins flashing. I tied the leads together to try and maybe clear any memory issues, no luck.

1st post has backstory

wait a sec, I skipped over that earlier.
You said the check engine light is flashing?
You can not clear an active code.
Count the flashes, that should lead us to the problem.
That Service Manual I posted earlier should help.
