December 28, 200520 yr my milage has started to suck, but a CEL poped up, fuel temp sensor! d'oh! and you can't just buy the sensor.. you've gotta replace the WHOLE fuel sending unit... arg! :-\ maybe i should bash the gas tank in with rocks...Check the manual for the wire routing and connector locations on the section of harness that runs back there. There's a better chance that that you've got a wire problem than a bad sensor (a rub-through to ground, corroded connector pin, etc.). If it does end up that the sensor is bad, it might work to build a "dummy sensor" using a resistor ... maybe you can fake the 'puter into turning off the light. I think the manual usually gives the acceptable resistance range of the all the sensors. If it's based on the same thermistor that's used in the AIT sensor, the range is around 1k - 10k. 2k-3k for ambient 60-80 temp.
