P2667 Fuel Shutoff Valve "B" Control Circuit High
P2667 is a generic OBD2 powertrain code. It means “Fuel Shutoff Valve "B" Control Circuit High” — the same on every make and model, because the definition comes from the SAE J2012 standard rather than from the carmaker.

What the wording tells you
“High” here is electrical: the module saw the voltage in this circuit stay above its expected window. The usual causes are a short to voltage, a broken ground, an unplugged connector (many sensors read high when disconnected) — or the component itself.
“B”: where a car has several identical components, SAE tells them apart with letters. Which physical part is “B” is defined by the manufacturer — check the service information for your car before replacing it.
Can I keep driving with P2667?
The rule of thumb for this area (computer & output circuits): If the car runs normally, get it checked soon. A reference-voltage or processor code can come with stalling or limp mode — don’t rely on the car for long trips until it’s fixed.
How P2667 breaks down
Powertrain. Engine, transmission, fuel and emissions — the codes behind the check engine lamp.
Generic code: defined by SAE, the same on every make.
Computer & output circuits.
The specific fault within this range.
Where to look: Computer & output circuits
The control modules themselves and the circuits they drive: internal memory and processor self-tests, sensor reference voltages, glow plugs, coolant pumps, relays and other outputs.
Typical causes in this area
- Low or unstable supply voltage and poor grounds
- A shorted sensor pulling down a shared reference voltage
- Software that needs an update
- Water damage or a failed module

Brimly reads stored, pending and permanent codes through a Bluetooth LE or Wi-Fi OBD2 adapter, explains each one offline from the same 2,693-code dictionary as this page, and clears them once the fault is fixed — each clear goes into the car’s service history with the codes it removed. OBD diagnostics are part of Brimly Forever, a one-time purchase; the PRO assistant explains a code for your exact car.

Frequently asked
What does P2667 mean?
P2667 is a generic OBD2 powertrain code. It means “Fuel Shutoff Valve "B" Control Circuit High” — the same on every make and model, because the definition comes from the SAE J2012 standard rather than from the carmaker.
Can I drive with P2667?

What causes P2667?
“High” here is electrical: the module saw the voltage in this circuit stay above its expected window. The usual causes are a short to voltage, a broken ground, an unplugged connector (many sensors read high when disconnected) — or the component itself. Typical causes in this area: Low or unstable supply voltage and poor grounds; A shorted sensor pulling down a shared reference voltage; Software that needs an update; Water damage or a failed module.
How do I clear P2667?
Fix the cause first, then clear it with any OBD2 scanner or app. Once the fault is gone the car also clears it on its own: the check engine lamp goes off after the self-test passes on three drive cycles in a row, and the stored code ages out after about 40 warm-ups. Clearing without a repair only hides it for a while — and resets the readiness monitors an emissions inspection looks at.
Is P2667 the same on every car?
Yes. P2667 is a generic SAE J2012 code, so its definition is identical on every make and model. What differs is the cause behind it and the repair procedure, which depend on the engine — that’s why the assistant on this page asks for your car.
