What does engine code P0004 mean?

OBD-II Code P0004 is defined as a Fuel Volume Regulator Control Circuit High. The Fuel Volume Regulator allows the fuel system to release excessive fuel from the engine back to the fuel tank.

What does control circuit high mean?

If the fuel pump “A” control circuit is faulty, the P0629 code is stored. This often means that the malfunction is in a certain area of the system, as opposed to any one component or circuit. Usually, the P0629 code is caused by a defective fuel pump, or a problem with the fuel pump relay.

How do I fix code P0036?

The most common repairs to resolve a P0036 fault code are:Verify the code with an OBD-II scanner, and reset the fault code. Follow this with a test drive of the car to see if the trouble code clears. ... Repair or replace any loose or damaged wiring to the HO2S, including checking for proper voltage and ground.Replace HO2S.

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 cause of P0001?

The P0001 fault code could cause your vehicle from running, you may experience: Inefficient fuel economy. Fuel instability which may damage your engine. Potentially damage your catalytic converters, which is an expensive repair. Prevent you from passing emissions.

What is the phone number for a mobile mechanic?

What is the code for fuel pressure regulator?

The P0001 code is associated with the electrical circuit which connects to your fuel pressure regulator. It also may be related to other codes, such as: P0002, P0003, or P0004.

Can you clear the code and test drive a vehicle?

They may clear the code/light and test drive the vehicle while monitoring data to see if it returns. Based upon the conditions of the testing, possibly clearing the code and performing a road test, further diagnosis may be required. Diagnosis may require multiple electrical tools such as:

What Does Code P0001 Mean?

The diesel fuel system contains a low-pressure and high pressure side. The low pressure side consists of the tank, pump, filters, water separator, bleeder valves and necessary fuel lines. The high pressure side varies according to injection type, but typically consists of a high pressure pump and fuel rail.

What are the symptoms of code P0001 ?

Besides an illuminated check engine light, there are other symptoms that might accompany a P0001 code. These include lack of power and a no start condition.

What tools are needed to diagnose ECM?

Diagnosis may also require multiple tools, such as: Advanced scan tools for reading ECM data values. If after repeated tests you see code coming back, then you will have to inspect the connectors and wiring that connect to the fuel volume regular circuit and its system.

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.
