P2667 code definition

The P2667 code identifies a problem with the fuel shutoff valve.

The P2667 code is often associated with the P2666 and P2667 trouble codes.

What the P2667 code means

P2667 is the OBD-II generic code for a problem with the fuel shutoff valve. A circuit is “closed” when it is functioning properly. If the circuit is “open”, then there is a disconnection within the circuit. An “open” circuit is indicated by the P2667 code. “Open” and “closed” are the only two positions possible with this type of circuit.

The location of the particular control circuit; “valve B” in this case, varies depending on the vehicle.

What causes the P2667 code?

The P2667 fuel shutoff valve code may have several causes:

  • A wire within the fuel shutoff valve circuitry has been disconnected.

  • Damage, often resulting from some sort of collision, has caused the fuel shutoff valve to become deactivated.

  • There was a short circuit within the circuitry of the fuel shutoff valve.

What are the symptoms of the P2667 code?

The Check Engine light on the vehicle's dashboard will illuminate to accompany the P2667 code. Depending on the vehicle, the engine may be totally unable to start once the P2667 code appears. In some cases the vehicle will start and run but suffer from problems within the fuel delivery system. The engine may run roughly and inconsistently.

How does a mechanic diagnose the P2667 code?

P2667 is diagnosed with an OBD-II code scanner that is capable of scanning the factory readings when connected to the vehicle via a special port. A qualified technician will perform the diagnosis. The first thing they will do is observe when exactly the code was first activated. Once that is done, they will reset the code and test the vehicle.

The vehicle should start and run once the code has been reset. If, during the course of the test, the same code appears again, then an inspection of the wiring and electrical connections surrounding fuel shutoff valve B will take place. If no observable problems are noted, then the technician will perform a test of the circuit using a multimeter and an oscilloscope to ensure that proper voltages are flowing through all of the test points.

Common mistakes when diagnosing the P2667 code

The P2667 code will be accompanied by the Check Engine Light illuminating. Despite this, the symptoms are still often misdiagnosed. Usually when this occurs, the fuel pump and other components of the fuel delivery system are repaired or replaced unnecessarily. To avoid this, clear the P2667 code and test drive the vehicle to see if the code appears again. If it does, then the P2667 code is the likely cause of the fuel delivery issues.

How serious is the P2667 code?

The P2667 code is capable of rendering the engine unable to start in many applications. In instances where the engine can still start and run, there will likely be problems with fuel delivery stemming from the P2667 code. For these reasons, the P2667 code is serious enough that it should be diagnosed and, if necessary, repaired by a qualified technician when it appears.

What repairs can fix the P2667 code?

The most common potential repairs to address the P2667 code are as follows:

  • Inspect the wiring and electrical connections in and around the fuel shutoff valve circuit for signs of corrosion, damage, or wear.

  • Any wires or connectors showing signs of damage should be replaced or repaired as necessary.

  • It is important to check the fuses that correspond to that part of the vehicle as well, as a random electrical issue could be the culprit if the code appears.

  • If the fuses and wiring are all in working order, then the fuel shutoff valve itself may require replacement.

  • If there is a problem with the circuitry surrounding the fuel shutoff valve or if a short in the circuit has caused serious damage, the circuitry may have to undergo significant repair or even total replacement.

Additional comments for consideration regarding the P2667 code

Given that the P2667 code corresponds with the fuel shutoff valve, it often appears after a rear collision. If this is the case, then there is probably damage in the fuel system that has caused this code to appear. If there has been no collision, the problem may still be within the fuel shutoff valve. To ensure that this is where the problem is, the code will be reset and then the vehicle will be test driven to see if it appears again. If it does not, then the problem may only be intermittent.
