Trouble Shooting Hints
The most likely causes for this DTC to be set are:
- Fuel temperature sensor failed.
- Open or shorted fuel temperature sensor circuit, or loose connector.
- PCM failed.
If the engine and the radiator have been flushed repeatedly when the engine coolant temperature was high (or the fuel temperature was high), a DTC could be output. Because this is not a failure, the DTC must be erased. Test drive the vehicle in accordance with the drive cycle pattern in order to verify that a DTC will not be output.
