Fuel Composition Sensor
Measures ethanol content so flexible-fuel vehicles can adapt fuelling between petrol and high-ethanol blends. Usually mounted in the fuel line beneath the vehicle, where road damage to the harness is a real cause.
Also known as: flex fuel sensor, ethanol sensor, fuel sensor, e85 sensor

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.
