How long does it take to diagnose a fault code?
Some fault codes may require more time to diagnose. With this particular code, the solution could be simple or require extensive time to diagnose and repair. Depending on your vehicle, it may take several hours to determine the root cause and repair. I have experienced this code in the past mostly on Ford vehicles.
What does ECM do?
The ECM regulates your fuel pressure from your fuel pump going to your engine through this circuit . When the computer detects a fault in the circuit, it will set a Check Engine Light. The code will affect fuel economy and possibly damage the engine.

What is the low pressure side of a diesel engine?
The low pressure side includes the filters, pump, tank, bleeder valves, water separator, and the important fuel lines. The components of the high pressure side on will vary depending on the type of injection, but it usually includes a fuel rail and pressure pump. Most modern common rail diesel engines have FVCV or fuel volume control valve as ...
What is the purpose of FVCV?
Its job is to regulate the volume of fuel to the high pressure pumping components from internal transfer pump. The valve meets the demands of the engine by adjusting the low pressure side.
What is the code for a catalytic converter?
Though quite an uncommon error code, P0001 must be properly addressed as it may cause drastic increase in fuel consumption of your vehicle, instability that may damage the engine, may compromise the catalytic converter (which can be an expensive repair) and prevent you from passing emission tests.
What causes fuel to leak back to low pressure circuit?
A fault in the fuel injector return system will cause the fuel pressure to be lower than expected. This causes fuel from the high-pressure circuit to be leaked back to the low-pressure circuit. A faulty maximum pressure relief valve will also cause this situation.
