Fuel Level Sensor Voltage Out of Range
The fuel level sensor voltage is outside the 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 in the tank measures how much fuel is left. If it shows a voltage that doesn't match what's expected, there’s a problem with the sensor or its connections.
What the computer is actually seeing
The ECM expects the fuel level sensor to output a voltage between 0.5V (empty) and 4.5V (full). If the voltage is less than 0.5V or more than 4.5V, it triggers this code.
What a healthy reading looks like
0.5V (empty) to 4.5V (full) for the fuel level sensor output.
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 — Verify that the tank has fuel. If low, fill it and see if the code returns.
- 22. Inspect the wiring and connections to the fuel level sensor for damage or corrosion. Repair as necessary.
- 33. With the key on (engine off), measure the voltage at the sensor connector. It should range from 0.5V to 4.5V. If it's out of range, go to step 4.
- 44. If voltage is outside the expected range, substitute the fuel level sensor with a known good one and check if the code clears.
- 55. If the code clears, replace the faulty sensor. If it doesn't, inspect the ECM for issues.
Common causes
- Faulty fuel level sensor
- Wiring issues or shorts in sensor circuit
- ECM malfunction
- Bad ground connection

Frequently asked questions
Is it safe to drive with this code?
It's generally drivable, but keep an eye on your fuel level. It could give inaccurate readings.
Will the code come back after clearing it?
If there’s an underlying problem, the code will likely return after a short drive.
Why does this code sometimes pair with SPN 1008?
SPN 1008 relates to fuel level too, indicating that both codes may emerge from the same sensor issue.
