P0180 — Fuel Temperature Sensor Circuit Malfunction
| Meaning | The engine computer noticed an electrical problem with the fuel temperature sensor circuit. This sensor measures how hot or cold your fuel is, helping the system adjust injection properly. The signal coming from the sensor is either missing, out of the expected range, or completely dead. |
| Family | Powertrain (P) |
Typical symptoms
Engine might be harder to start when cold
Possible rough running until the engine warms up
Common causes
Faulty fuel temperature sensor itself
Internal issue inside the engine control computer
What to do
Frequently asked questions
What does code P0180 mean?
Fuel Temperature Sensor Circuit Malfunction. The engine computer noticed an electrical problem with the fuel temperature sensor circuit. This sensor measures how hot or cold your fuel is, helping the system adjust injection properly. The signal coming from the sensor is either missing, out of the expected range, or completely dead.
Can I keep driving with code P0180 active?
Yes, no known limitation
Common causes — P0180
Bad connection or damaged wiring at the fuel temperature sensor plug Faulty fuel temperature sensor itself Internal issue inside the engine control computer
How do you fix code P0180?
Have a mechanic check the wiring plug and the sensor itself for loose pins, corrosion, or broken wires. It is best to look at this during your next routine service, but address it promptly if you notice starting issues.
