Troubleshooting 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.
• ECM (M/T) or PCM (A/T) failed.

If the engine and radiator have been flushed repeatedly when engine coolant temperature was high (or fuel temperature was high), a Diagnostic Trouble Code (DTC) could be output. Because this is not a failure, DTC must be erased. Make sure to test drive vehicle in accordance with drive cycle pattern in order to verify that a DTC will not be output.
