Fuel Shutoff Valve B Control Circuit High
What it means
P2667 means the control module detected high voltage (usually an open) in the "B" fuel shutoff valve control circuit — the valve that can cut fuel supply to the engine. Because this valve gates fuel, a circuit fault can, in some systems, cause stalling or a no-start, so it's worth checking promptly. The cause is usually wiring or connector damage, or a failed valve, rather than an engine problem.
Can I keep driving? Often drivable, but because this valve controls fuel supply a fault can cause stalling or a no-start in some systems — get it checked promptly.
Real-world scan data
Figures reflect only diagnostic scans recorded through our own apps and tools. Cars are typically scanned because a symptom or warning light prompted it, so these counts describe our scan records — not the incidence of faults in any model, and not the quality, reliability, or safety of any vehicle.

Common symptoms
What you'll notice
- Check-engine light on
- Possible stalling or hard/no-start in affected systems
- Engine may crank but not fire if the valve stays closed
- Often no symptom beyond the light if the valve still functions
Common causes
Most likely first
- High voltage / open in the fuel shutoff valve 'B' control circuitLikely
- Corroded, loose, or damaged connector at the valveCommon
- Chafed or broken control wiringCommon
- Failed fuel shutoff valve or its driverLess often
- On some vehicles, a shutoff valve deactivated by an inertia/rollover switch after an impactLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and inspect the fuel shutoff valve connector and wiring for an open or corrosion.
- On vehicles with an inertia/rollover switch, check that it hasn't tripped.
- Measure the valve's control-circuit voltage and the valve's resistance against spec.
- Repair wiring faults or replace the valve as needed.
- Clear the code and verify the engine starts and runs normally.
