P0006 code definition

The P0006 code is associated with an electrical circuit which connects from your engine computer to your fuel system and is most commonly found on diesel engines.

It also may be related to other codes, such as P0005 or P0007.

What the P0006 code means

P0006 is a generic OBD-II code indicating an issue with the engine control module (ECM) not receiving correct signals from your fuel shut-off valve. The fuel shut-off valve is located at the fuel supply rail mounted to your engine.

The ECM uses the fuel shut-off valve to prevent fuel from entering the engine when you turn it off. By doing this, the valve prevents your engine from continuing to run after you turn the key off (a term we call “dieseling”). The code will possibly cause dieseling or prevent the engine from starting. The Check Engine Light will also turn on.

What causes the P0006 code?

The Fuel Shutoff Valve "A" Control Low code may have several causes:

  • Possible short in the sensor connector
  • A shorted wire going to the ECM
  • A defective fuel shutoff valve
  • The ECM is damaged

What are the symptoms of the P0006 code?

The P0006 code will produce a Check Engine Light on the dashboard. Likely symptoms include:

  • Your engine continuing to run after the key is turned off
  • Your engine not starting because it cannot build fuel pressure
  • Possible stalling while driving

How does a mechanic diagnose the P0006 code?

P0006 is properly diagnosed with an advanced scan tool capable of factory sensor readings (not just one from an auto parts store) and a voltage meter. A qualified technician can read the data from the advanced scan tool to determine when the problem occurred, or if it is still occurring. They may clear the code and test drive the vehicle while monitoring the scan tool data to see if the fault returns or is constant.

Wiring may have to inspected for damage (which may require) cutting open the protective covering, inspecting the wiring harness, repairing the problem, and replacing the covering.

Based upon the conditions of the testing, possible clearing of the code(s), and a road test while monitoring the data, further diagnosis may be required. Diagnosis may require multiple tools such as:

  • An advanced scan tool to read the ECM data values
  • A digital voltage meter with attachments
  • Basic hand tools to access the sensor and wiring
  • A razor blade for wiring harness coverings

Common mistakes when diagnosing the P0006 code

Just replacing the fuel pressure shutoff valve doesn’t guarantee a successful repair and may be very expensive and labor intensive. It may be caused by several components in the electrical system and wiring as listed above or even more. Visual inspection and testing with the special equipment listed above will verify your issue before replacing the fuel shutoff valve unnecessarily.

I have seen people spend hundreds of dollars replacing this valve only to find out the problem was just a shorted wire or a damaged connector.

How serious is the P0006 code?

The P0006 fault code may cause your vehicle to have:

  • Lower fuel economy
  • Inability to start
  • Dieseling issues (not turning off)
  • Stalling issues at anytime while driving
  • Inability to pass emissions testing

A qualified technician can diagnose the problem with proper tools and can verify these potential issues and any effects on your other systems.

What repairs can fix the P0006 code?

The most common procedure to repair the P0006 code is as follows:

  • Connect a professional scan tool to verify the code exists.

  • Perform research from professional sources for testing and values based upon the code.

  • Check for any other fault codes which may be related to the issue.

  • Perhaps clear the fault codes to see which fault codes return.

  • Analyze scan tool data from the ECM.

  • Road test the vehicle while analyzing the scan tool data from the ECM with other tools attached.

  • Verify if the P0006 code returns or the symptoms exist.

  • Inspect all of the items listed above (wiring, voltages, etc.)

  • Further diagnose the problem with the special tools listed above if the problem appears to repeat.

  • The signals and wiring from the sensor require analyzing to determine where the problem exists. If the signals are fine, then further testing of the the wiring, computer, or fuel system is required.

  • Replace the fuel shutoff valve, wiring, or the faulty component.

Additional comments for consideration regarding the P0006 code

Any electrical related code may persist all of the time or may occur intermittently. Some fault codes will require additional time to diagnose. With this code, the solution may be simple to replace or require extensive time to diagnose and repair. Depending on your vehicle, it may take several hours to determine the root cause and repair of the faulty component.

The P0006 code involves many systems and requires extensive diagnosis. After using a scan tool and monitoring the voltage readings, a qualified technician can determine if the fuel shutoff valve, wiring, or other component is at fault. With the scan tool connected, I evaluate the data while checking the voltage meter to ensure all the values match, meet specifications, and perform a visual inspection. From there, pinpointing where to start further diagnosis can begin.

The fuel shutoff valve may be the cause, wiring might be burning/rubbing on another engine component, rodents may have chewed through wiring anywhere in the vehicle, connectors may have shorts or damage, or you may have a bad ECM.

Vehicles with higher mileage may just need a fuel shutoff valve replacement. However, replacing parts based upon a code is not recommended and has caused problems or not resolved the issue after spending a large amount of money. I have seen the part replacement cost people hundreds of dollars and not repair the problem.
