P2667 — Fuel Shutoff Valve "B" Control Circuit High

powertrain (engine/transmission)

Is it safe to drive?

Short-term driving is OK In most cases the car remains drivable, possibly with reduced performance or a disabled auxiliary system. If symptoms include stalling, no-start or brake/steering warnings, treat it as urgent.

How to diagnose with an OBD scanner

  1. Read the code and freeze frame Connect an OBD2 scanner, confirm P2667 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
  2. Check for companion codes and TSBs Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many P0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
  3. Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the fuel shutoff valve "B" control for damage, corrosion, chafing or poor contact.
  4. Subsystem check With the fuel shutoff valve "B" control disconnected, measure signal voltage at the harness connector: a high reading with the component unplugged indicates a short to power in the harness; if it drops to normal, the component itself is faulty.
  5. Subsystem check Measure reference voltage, ground and signal continuity at the component connector.
  6. Subsystem check Wiggle-test the harness while watching the signal in live data — dropouts reveal broken wires.
  7. Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P2667 does not return.

Approximate repair cost

Repair cost depends on which component actually failed. Typical scenarios for P2667 (parts and labor, USD, independent shop rates): Control module repair: $300–$1,000; Repair wiring or connectors: $80–$250; Replace the faulty sensor or actuator: $150–$500. Overall, fixing P2667 usually costs between $80 and $1,000. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.

Common questions

Will P2667 clear itself?

Sometimes P2667 clears after a few drive cycles if the fault was intermittent — for example a loose connector or a tank of bad fuel. The underlying cause usually remains, so the code tends to return. Clear it once; if it comes back, diagnose rather than erase it repeatedly.

How do I diagnose P2667 myself?

Start with a scan: confirm P2667, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the fuel shutoff valve "B" control, and verify the suspect component against live data before buying parts.

Is it safe to drive with P2667?

In most cases the car remains drivable, possibly with reduced performance or a disabled auxiliary system. If symptoms include stalling, no-start or brake/steering warnings, treat it as urgent.

What are the symptoms of P2667?

Drivers most often notice: the affected system operates intermittently or not at all, increased fuel consumption in some cases, Check Engine Light on, possible limp mode depending on the affected component.

What does OBD2 code P2667 mean?

Fuel Shutoff Valve "B" Control Circuit High (P2667): a powertrain (engine/transmission) fault affecting the sensor and actuator circuits. The car is usually drivable while you plan the repair. Most often caused by blown fuse feeding the circuit, corroded, loose or damaged connector, control module driver fault.

What does P2667 mean?

When P2667 appears on a scan, it means the control module has flagged a problem in the sensor and actuator circuits: fuel shutoff valve "B" control circuit high. The fault sits in the powertrain (engine/transmission) group of the OBD2 standard.

“Circuit high” means the control module sees a voltage on the fuel shutoff valve "B" control circuit that is above the expected range — typically close to battery voltage. Physically this points to a short to a power feed, a broken ground return, or a failed component pulling the signal line high.

This code does not appear from a single bad reading: the module must see the fault condition repeat under defined operating conditions before it turns on the warning light. The freeze frame captured with P2667 — engine load, rpm, temperature, speed — tells you exactly when the problem occurs, so reproduce those conditions when testing.

What causes P2667?

  • open ground return of the fuel shutoff valve "B" control
  • failed fuel shutoff valve "B" control pulling the signal high
  • signal wire shorted to battery positive
  • poor ground connection
  • open or shorted wiring in the circuit
  • blown fuse feeding the circuit
  • corroded, loose or damaged connector

Common symptoms of P2667

  • the affected system operates intermittently or not at all
  • increased fuel consumption in some cases
  • Check Engine Light on
  • possible limp mode depending on the affected component

How to diagnose P2667

  1. Connect an OBD2 scanner, confirm P2667 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
  2. Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many P0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
  3. Visually inspect the wiring harness and connectors related to the fuel shutoff valve "B" control for damage, corrosion, chafing or poor contact.
  4. With the fuel shutoff valve "B" control disconnected, measure signal voltage at the harness connector: a high reading with the component unplugged indicates a short to power in the harness; if it drops to normal, the component itself is faulty.
  5. Measure reference voltage, ground and signal continuity at the component connector.
  6. Wiggle-test the harness while watching the signal in live data — dropouts reveal broken wires.
  7. Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P2667 does not return.

How to fix P2667

Start with the cheapest and most common causes before replacing expensive parts:

  • Control module repair — $300–$1,000
  • Repair wiring or connectors — $80–$250
  • Replace the faulty sensor or actuator — $150–$500
