There indeed was a fuel temp sensor circuit. At least a wire at the pin.
Pinout chart said it should measure 2.8 to 3.4 volts key on, 77 degrees outside.
I measured it and it read about 5-6ish, don't recall excactly.
So I took the wire and soldered in a 270 ohm resistor on it in series to ground. Volts dropped on the pin to about 4.5
So I added in more resitors in series until I got the measurement to just under 3 volts.
Took 4, 270 ohm resistors to get there.
Cleared codes and bang, check engine light off for the first time since installation of the EJ engine (about a month)
I didn't like all the resitors in series, so I just went to radio shack and got a 1k ohm resistor (1/2 watt rated) and put it in instead. Works
So there you go eveybody.......1k resistor tricks the Fuel temp circuit FTW
