P0006 Error code fuel shut off valve
P0006 Error code is associated with an electrical circuit that connects from your engine computer to your fuel system and is most commonly found on diesel engines. It may also be associated with other codes such as P0005 or P0007.
Meaning of error code P0006
Error Code P0006 is a common OBD-II code that indicates an issue with the engine control module (ECM) not receiving the correct signals from your fuel shutoff valve. The fuel shutoff valve is located on the fuel feed rail mounted on your engine. The ECM uses the fuel shutoff valve to prevent fuel from entering the engine when you shut it off. By doing this, the valve prevents your engine from continuing to run after you turn the key off.
What causes the P0006 Error code?
There may be several causes for the P0006 Error Code Fuel Shutoff Valve "A" Control Low code:
Possible short circuit in the sensor connector
A shorted wire to the ECM
A faulty fuel shutoff valve
ECM Malfunction
What are the symptoms of the P0006 Error code?
The P0006 Error Code will produce a Malfunction Engine Light on the dashboard. Possible symptoms include:
Your engine continues to run after the key is turned off
Your engine won't start because it can't create fuel pressure.
Possible stalling while driving
How to diagnose the P0006 Error code?
The P0006 Error Code is accurately diagnosed with an advanced scan tool and a voltage meter capable of taking factory sensor readings. can read data from the advanced scan tool to determine when the problem occurred or if it still persists. They can clear the code and test the vehicle while monitoring the scan tool data to see if the fault returns or is fixed. It may be necessary to cut the protective covering, inspect the wiring harness, repair the problem, and replace the covering. Further diagnostics depending on test conditions, possible deletion of the code(s) and a road test while monitoring data
It may be necessary. Diagnostics may require multiple tools, such as: An advanced scan tool to read ECM data values A digital voltage meter with attachments Basic hand tools to access the sensor and wiring A cutting tool for wiring harness shrouds
Common errors when diagnosing error code P0006
P0006 Error Code, Simply replacing the fuel pressure shutoff valve does not guarantee a successful repair and can be very expensive and labor intensive. It can be caused by one or more of the various components in the electrical system and wiring as listed above. Visual inspection and testing with the specialized equipment listed above will confirm your problem before unnecessarily replacing the fuel shutoff valve. The problem may simply be a shorted cable or a damaged connector.
How serious is the P0006 Error code?
P0006 Error Code can cause the following in your vehicle:
Lower fuel economy
Engine not starting
Diesel problems (inability to stop)
Problems stopping at any time while driving
Failure to pass emissions test
How to fix P0006 Error code?
The most common procedure to repair the P0006 Error Code is as follows:
Connect a professional scan tool to verify the code is present. Research professional sources for code-based testing and readings. Check for other error codes that may be related to the problem. Perhaps clear the error codes to see what error codes return. Analyze scan tool data from the ECM. Road test the vehicle while analyzing scan tool data from the ECM with other attached tools. Verify if code P0006 returns or if symptoms are present. Check all items listed above (wiring, voltages, etc.) If the problem seems to reoccur, further troubleshoot the problem with the specific tools listed above.
diagnose. Signals from the sensor and wiring require analysis to determine where the problem lies. If signals are good, further testing on the wiring, computer or fuel system is required. Replace the fuel shutoff valve, wires, or faulty component.
Additional comments to consider regarding the P0006 Error code
P0006 Error Code Any electrical related code may persist all the time or occur intermittently. Some error codes require additional time to diagnose. With this code, the solution may be simple to replace or may require a long time for diagnosis and repair. Depending on your vehicle, it may take several hours to determine the root cause and repair the faulty component. Code P0006 involves many systems and requires extensive diagnostics. After a qualified technician uses a scan tool and
After monitoring voltage readings, it can determine if there is a malfunction in the fuel shutoff valve, wiring, or other components. With the scan tool connected, it evaluates the data while checking the voltage meter to ensure all readings match, meets specifications, and performs a visual inspection. From there, pinpointing where to begin further diagnosis can begin. This could be due to the fuel shut off valve, the wires could be rubbing on another engine component, rodents may have chewed through the wires elsewhere in the vehicle, the connectors may be shorted or damaged, or your ECM may be bad. On vehicles with higher mileage, only the fuel shutoff valve may need to be replaced. However, replacing parts based on a code is not recommended.
