Symptoms
- Fuel pump icon lit, often with a low-range estimate
- Fuel gauge needle near or below E
- No other symptoms
Likely causes
- CommonFuel tank genuinely lowThe most straightforward and common reason.
- PossibleFaulty fuel level sensor/sending unitCan cause an inaccurate low reading even with more fuel in the tank.
What to do
- Plan to refuel soon; most cars have some reserve range left, but it varies by model.
- Avoid aggressive driving, which uses more fuel and shortens remaining range.
- Refuel at the next safe opportunity rather than pushing to empty.
- If the light comes on with what you know is a full or half-full tank, suspect a sensor issue.
- Have the fuel level sending unit tested if the gauge behaves erratically or doesn't match actual fuel added.
When to call a pro
See a mechanic only if the light seems inaccurate compared to how much fuel you actually have.
