Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition




The engine control module (ECM) checks the signal from the fuel temperature sensor.
The diagnostic trouble code (DTC) is stored if the control module detects that the value from the fuel temperature sensor deviates too much from the values for engine coolant and intake temperatures after the engine has been switched off for an extended period.
The diagnostic trouble code can be diagnosed at ignition on after the engine temperature has dropped by at least 55 °C from fully warm engine (higher than 70 °C).

Substitute value
- The signal from the engine coolant temperature (ECT) sensor is used.

Possible source
- Contact resistance in the connectors.
- Damaged fuel temperature sensor.

Fault symptom[s]
- Nothing.
