Find your metal fuel return line on the drivers side of the engine, there is a port in the metal line where the fuel temp sensor screws into. I have this same code, even after changing that sensor. Might be another electrical connector issue. I Found out, to buy the electrical connector, the dealership wants about $40 more than what I paid for the sensor from the same dealer. There must be a better place to buy these electrical connectors from other than the dealer?
