Fuel Control Valve Position Sensor Circuit Low
The fuel control valve position sensor is reading a low signal.
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 control valve position sensor tells the computer where the valve is positioned. If it's reading low, it thinks the valve is closed when it shouldn't be.
What the computer is actually seeing
The computer expects a voltage signal from the sensor indicating the position of the fuel control valve. Low voltage (typically below 0.5V) means the valve is likely not moving as expected.
What a healthy reading looks like
Expected voltage from the sensor should be between 0.5V to 4.5V depending on valve position during operation.
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 wiring and connectors for damage or corrosion; repair as necessary.
- 22. Inspect the fuel control valve for proper operation and mechanical binding.
- 33. Test the fuel control valve position sensor with a multimeter; expected output should be 0.5V to 4.5V. If it’s lower, replace the sensor.
- 44. If the sensor output is okay, check for fluid contamination or blockage affecting the valve operation.
Common causes
- Damaged wiring or connectors
- Faulty fuel control valve position sensor
- Incorrectly set valve position due to mechanical issues

Frequently asked questions
Is it safe to drive with this code?
It's still drivable but fix it soon as fuel efficiency and performance can be affected.
Will this code come back if I just clear it?
If the underlying issue isn't resolved, this code will likely return.
Why does this code appear with SPN 3001?
SPN 3001 usually indicates a problem with the fuel control itself, which can affect the sensor readout.
