Fuel Volume Regulator Control Range/Performance Problem
There's a problem with the control of the fuel volume regulator.
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 car's computer is getting weird data from the fuel volume regulator that controls how much fuel gets to the engine. This could mean it's too high or too low, affecting performance.
What the computer is actually seeing
The engine control unit (ECU) expects the fuel volume to be within a specific range to maintain optimal performance. If it sees values outside of this range for more than a set number of cycles, it triggers this code. For example, if the fuel pressure is supposed to be between 30-60 psi, but the sensor reads below 20 psi or above 70 psi, it will throw the code.
What a healthy reading looks like
Expected fuel pressure at the rail is typically between 30-60 psi, but the exact value will depend on the vehicle specifications.
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 and make sure it's adequate; refill if it's low.
- 22. Inspect the wiring and connectors to the fuel volume regulator for damage or loose connections; repair as needed.
- 33. Test the fuel pressure using a gauge; it should be within the expected values.
- 44. If the fuel pressure is low, check and replace the fuel filter if clogged; then re-test fuel pressure.
- 55. If the pressure is still out of range, replace the fuel volume regulator; re-check after installation.
Common causes
- Faulty fuel volume regulator
- Bad fuel pressure sensor
- Clogged fuel filter
- Damaged wiring or connectors to the regulator
- Low fuel level or quality issue in the tank
Typical repair cost
$$ (150-400)

Frequently asked questions
Can I drive my vehicle with this code?
Yes, but expect reduced performance and efficiency; address it soon to avoid further issues.
Why does this code appear with others like P0087?
Both codes relate to fuel pressure issues, so they might appear together if there's a fuel system fault.
