error code 23 fuel thermosensor
 

Hello all,

I recently tossed a jdm motor into a usdm shell and am throwing a code 23. Not sure where this sensor is or what it looks like. I used a jdm main engine harness and to make the harness connect changed the jdm plugs on the harness for usdm. This leaves one misterious wire no one seems to know what its for. Is this the wire throwing the code? or would it be something else?

Thanks again,
