Can drive — fix at your convenience.
This code means the computer detected an intermittent or erratic signal from the fuel level sensor circuit. It's usually caused by loose or corroded wiring and connectors, a worn fuel level sensor, or a float that occasionally sticks inside the tank. Repairs typically involve cleaning or repairing the wiring and connectors or replacing the fuel level sending unit.
$150 – $500
Varies by vehicle and root cause.
Yes, it's safe to keep driving. The engine isn't affected, but your fuel gauge may be unreliable, so keep an eye on your mileage so you don't run out of fuel unexpectedly.
Repairs usually cost between $150 and $500. A simple wiring or connector cleanup is on the low end, while replacing the in-tank fuel level sending unit costs more due to labor.
No, it's low severity. It mostly affects the accuracy of your fuel gauge and doesn't threaten the engine. The practical risk is misjudging how much fuel you have left.
The intermittent fault in the fuel level sensor circuit feeds bad data to your gauge, making it jump or stick. Once the wiring or sensor is repaired, the gauge should read correctly again.
