P0180 = fuel temperature sensor A circuit malfunction

I don't know first hand what happens when the fuel temp signal goes outside of the allowed limits, but the trouble code says there's something wrong with it. Unfortunately it doesn't give any more details. Could be a missing signal (corroded or disconnected wires), or the sensor has gone bad and is either dead or returning signal that is way out of normal range.

That, or your fuel temperature for some reason really is abnormal :)

Here are other related codes for the fuel temp, maybe this will help you diagnose it further... since these codes are not stored in memory, it probably is NOT one of the described faults:

All of the other codes seem to indicate that there is SOME kind of response from the sender. Your code simply says malfunction, possibly no signal at all (Break in wiring or completely dead sensor)
