Probable Cause

Fuel temperature sensor failed.
Open or shorted fuel temperature sensor circuit, or loose connector.
PCM failed.

NOTE: A DTC could be output if the engine and radiator have been flushed repeatedly when the engine coolant temperature was high (or fuel temperature was high). Because this is not a failure, erase the DTC. Then test drive vehicle following OBD-II drive cycle Other Monitor pattern. See OTHER MONITOR under OBD-II DRIVE CYCLES under VERIFYING REPAIRS. Check for DTCs. Verify DTC is not output.
