Fuel Level Sensor Out of Range
The fuel level sensor is reporting a voltage that is out of expected range.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The fuel level sensor measures how much fuel is in the tank, but its signal is too high or low for the engine computer to accept.
What the computer is actually seeing
The ECU monitors the fuel level sensor, expecting a voltage between approximately 0.5V (empty) and 4.5V (full). If it reads below 0.1V or above 4.9V, it triggers this fault code.
What a healthy reading looks like
Expected voltage from the fuel level sensor should be between 0.5V and 4.5V while the engine is running.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Check the fuel level in the tank. If it's very low, refill to a reasonable level and recheck the code.
- 22. Inspect wiring and connectors to the fuel level sensor for any visible damage or corrosion. Repair as necessary and retest.
- 33. Using a multimeter, measure the voltage at the fuel level sensor while the ignition is on. Look for values between 0.5V and 4.5V.
- 44. If voltage is out of range, replace the fuel level sensor and recheck.
- 55. If voltage is normal, check for shorts or opens in the wiring harness leading to the ECU.
Common causes
- Faulty fuel level sensor
- Wiring issues to the fuel level sensor (shorts or opens)
- Corroded connectors
- Faulty engine control unit (ECU)
- Low fuel levels affecting sensor output

Frequently asked questions
Is it safe to drive with this code?
It's drivable but may lead to inaccurate fuel level readings, so fill up as needed.
Will this code come back?
If the underlying issue isn't fixed (like a bad sensor or wiring), the code will likely return.
Why do I see this code with SPN 0562?
SPN 0562 indicates an out-of-range low signal, while SPN 0563 indicates an out-of-range high signal; they both point to issues with the fuel level sensor or its circuit.
