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:


P0180Fuel Temperature Sensor A Circuit Malfunction
P0181Fuel Temperature Sensor A Circuit Range/Performance
P0182Fuel Temperature Sensor A Circuit Low Input
P0183Fuel Temperature Sensor A Circuit High Input
P0184Fuel Temperature Sensor A Circuit Intermittent
P0185Fuel Temperature Sensor B Circuit Malfunction
P0186Fuel Temperature Sensor B Circuit Range/Performance
P0187Fuel Temperature Sensor B Circuit Low Input
P0188Fuel Temperature Sensor B Circuit High Input
P0189Fuel Temperature Sensor B Circuit Intermittent



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)
