What does this fault code mean?
The engine control module has found the fuel temperature sensor signal to be too high and treats this as a fault. The fault is checked only while the engine runs, so the lamp may take a while to go out after a repair. The sensor measures fuel temperature, and a wrong signal gives the control module incorrect data. The cause is either a signal wire that has come into contact with supply voltage or a damaged sensor.
Possible causes
- Signal wire shorted to supply voltage
- Damaged fuel temperature sensor
What you can do
- 1Read and note the code, clear it and road test to see whether it returns
- 2Check that the connector at the fuel temperature sensor is fully engaged and free from corrosion
- 3Follow the signal wire from the sensor and look for chafing, pinched sections and places where it may touch another wire
- 4With the ignition on and the sensor connector unplugged, use a multimeter to see whether the signal wire picks up voltage
- 5With a diagnostic tool, check that fuel temperature follows engine warm-up in live data. A value stuck high points to the sensor or wiring
- 6If the fault returns, have a workshop with diagnostic equipment decide whether the sensor needs replacing
