Okay. Unless theres a different place I should be checking it all looks okay. I've checked where the sensor plugs in, and where the harness comes from under the tank which is kinda twisted up but otherwise I think it looks good. Only thing is theres an orange and white cable that has some pinching but afaik it isnt to anything important or related, am I wrong? And the connection to the ecm looks good.

Update: I was thinking about everything on the bike and everything looked fine, everything was plugged in right as far as I could tell, I didn't think there was any reason I should doubt the integrity of the ECM, any wires as far as pinches or breaks, the battery, the sensor, or anything so it didn't make any sense to me that I should have any issues and the only thing that bugged me was all the wires attached to my positive terminal on my battery(like 3) so I checked it and there was maybe a tether? Still not sure but I just disconnected it and everything was fine, no more P0374 and I finally took it for a ride. Moral of the story is, if you have an error but everything looks fine and should be fine, could be something else entirely. So if this helps anyone, awesome.

Hey man, i'm having the exacte same issue you've mentionned. is there anything else you did ?!
Mine just happened one day, stopped starting, just cranks. i've check my ECM pins 12 and 30 and i'm receiving the right signals, 3-4 VAC in pulses as it cranks.
Yet the code stays and the bike doesn't start.
Thanks

Man, its been a while since that happened lol
I think.. I had a few wires connected to the battery that I didnt even know what they were attached to and they didnt need to be and they were interfering somehow. So I think, after replacing the sensor like twice, clearing the codes, changing the fuses, and it still didnt work, I just ended up being as basic as possible with how I connected a new fully charged battery(basically, minus anything extra) and it started. I really had no idea wtf happened or how I fixed it but I was so thrilled I hopped on and immediately got it out onto the road and up into triple digits lol
might not be your issue and Im by no means a mechanic but maybe you attached something wrong somewhere, maybe someone ****ed with your battery if they thought about stealing your bike, maybe youre experiencing some kind of other electrical issue. Could be something unrelated. As far as I can tell my issue wasnt even the sensor, it just registered that way for some reason. My only other electrical issue I had with that bike was the stator going bad.
good luck dude.
