P0183: Fuel Temperature Sensor A Circuit High
What to do
Usually driveable. Have the connector inspected before the sensor is replaced.
What this code means
The fuel temperature signal is above its valid range, usually an open circuit or a short to supply. A corroded connector that has lost contact presents identically to a broken wire, and on an underfloor sensor corrosion is the more common of the two.
Likely causes
Start here
- Open circuit in sensor wiring · moderate
- Corroded or loose connector · easy
- Faulty fuel temperature sensor · moderate
Less common
- Wiring shorted to voltage · moderate

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
