Fuel Level Sensor Circuit Range/Performance Problem
Fuel level sensor is not reading correctly or is out of 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 your tank is telling the computer that the fuel level is off. It might read too high or low, confusing the system about how much gas is really there.
What the computer is actually seeing
The powertrain control module (PCM) expects to see a signal from the fuel level sensor that represents the fuel level in volts (typically 0.5V to 4.5V). If the signal is outside this range or erratic, the code will trigger.
What a healthy reading looks like
Voltage should be between 0.5V (empty) and 4.5V (full). The expected resistance values for the sensor should be between 5 ohms (full) and 250 ohms (empty).
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. Inspect the wiring and connectors to the fuel level sensor for any visible damage or corrosion. Repair as needed. Decision: If wiring looks good, proceed to step 2. If damaged, repair and retest.
Common causes
- Faulty fuel level sensor
- Wiring issues or corroded connectors
- Faulty PCM
- Ground issues on the fuel level circuit
Typical repair cost
$150-$400

Frequently asked questions
Is it safe to drive with this code?
Yes, but fuel level readings may be inaccurate. Keep an eye on fuel levels manually.
Will this code come back after I clear it?
If the problem isn't fixed, it will likely return.
Why does this code show up with other codes?
Related codes may indicate issues in the same circuit or subsystem, which can affect fuel level readings.
