P2667 - OBD Trouble Code

<<See All OBD Codes

The trouble code P2667 can be explicated as Fuel Shutoff Valve “B” Control Circuit High. If the engine control module would detect a variation in the voltage coming from the fuel shutoff valve “B” control circuit delivered performance that is outside the parameters set by the automobile manufacturer, then it would store the P2667 fault code. This would give rise to the flashing up of the check engine light.

The P2667 error code is often related with the P2666 and P2667 trouble codes. This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it depends upon the vehicle make and model. The engine control module, powertrain control module or the transmission control module monitors this circuit depending upon the particular automobile.

What causes this problem with the Fuel Shutoff Valve “B” Control Circuit High?

• The fuel shutoff valve 'B' might be flawed
• Fuel shutoff valve 'B' harness is not shut or tiny
• There might be a poor electrical connection in the fuel shutoff valve 'B' circuit
• There can be inoperative powertrain control module

1. Engine Control Module - Want to know the most common reason behind the failure in the engine control module? Corrosion or damage because of moisture can cause ECM failure. Corrosion might enter the ECM through the wiring harness and moisture can enter by a failure in the seals in the ECM itself.
2. Fuel Injector - Facing some issues in starting your vehicle? Poor idle issues? Failed emissions? These are all the symptoms of bad, faulty, leaking and clogged fuel injectors. It would be a good decision to replace your defective fuel injector with a new one online.
3. Fuel Pressure Regulator - A fuel pressure regulator is a device used to control the pressure of fuel supplied to the fuel injectors on an engine, even during dramatic changes in fuel demand. Controlling this pressure is needed so that the fuel injectors can receive and dispense fuel at a known rate. So, it is important to replace faulty regulator now!
4. Powertrain Control Module - The PCM makes the engine and transmission work in tandem. Any issue with the powertrain control module will cause major problems with the efficient running of the vehicle.
5. Electronic Control Unit - If your vehicle fails to start for no apparent reason, this is also a good indicator that there can be some issues with the ECU. If you check the car battery, starter and other common electrical components, and the vehicle still does not start, a quirky electronic control unit should be the next logical thing to consider.
6. Diagnostic Tool - In order to fix these errors, you need a few diagnostic tools to get your car problems pointed out easily. Our diagnostic tools collection will come in handy to do so and resolve all your vehicle problems. Visit today!

It is vital to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P2667 here:

Common Symptoms

• Check engine light might come into signal
• Decline in the engine performance
• The overall fuel consumption might start rising
• Blocking of the car engine

The repairs which you will have to do to correct this fault code are simply straightforward; you can surely pinpoint the necessary repairs on the basis of your diagnosis. Have a look at some common fixes:

• Repair or replace the quirky fuel shutoff valve 'B' circuit
• The fuel shutoff valve should be restored to working order
• Recondition the non-functioning wiring and electrical connections in and around the fuel shutoff valve circuit
• It is necessary to perform proper service of the unsound fuel shutoff valve 'B' harness

Here are some steps which you should follow in order to diagnose this fault code:

• This is a general type of error code which is diagnosed with the help of a scanner.
• The mechanic will insert a scanner to diagnostic port of the vehicle and recover the codes and freeze frame data.
• If he happens to find any additional error codes, he has to address them as well.
• Once it is done, he has to reset the vehicle, and then test drive to see if the error code appears.
• If the error code does not return, then there can be an erratic condition.
• But, if the error code returns, then the mechanic has to check the wiring and electrical connections surrounding fuel shutoff valve B.
• If the fuel shutoff valve B is defective, then it has to be replaced.
• Also, the mechanic can check for any sign of defects in the related parts, then he should quickly fix the issue.
• Then the mechanic has to check the wires, connectors and other electrical components and quickly replace them if he finds them to be damaged or defective.
• If the issues are not yet sorted out, then the mechanic will use a digital voltmeter/ ohmmeter and connect it to the vehicle.
• Once the circuit is inspected, he will thoroughly check all the harness and repair them accordingly.
• Whenever the mechanic or a trained professional, repairs any of the component like wires or connectors, he will reset the code and test drive the vehicle again to see if the error code appears again.
• This can actually help the mechanic to know if the problem is fixed.

Common Mistakes When Diagnosing The P2667 Code

The P2667 fault code would be accompanied by the illumination of the Check Engine Light. Despite this, the symptoms are still often misdiagnosed. Generally when this would occur, then the fuel pump and other components of the fuel delivery system are repaired or replaced unnecessarily. This can be avoided by clearing the P2667 error code and then the vehicle should be taken out for a test drive to see if the code appears again.
