What does the code p0004 stand for?
The combination of the FVCV and the fuel pressure control valve (FPCV) is used to correctly supply fuel to the engine. The fuel pressure sensor monitors FVCV and FPCV operation and informs the powertrain control module (PCM) of any changes. The code P0004 stands for fuel volume regulator control circuit.
What does p0004 stand for in Powertrain Control Module?
The fuel pressure sensor monitors FVCV and FPCV operation and informs the powertrain control module (PCM) of any changes. The code P0004 stands for fuel volume regulator control circuit. The PCM monitors the state of the FVCV circuit and sets this code when it finds a high circuit.
What does p0004 mean on a check engine light?
P0004 is a diagnostic trouble code (DTC) for “Fuel Volume Regulator Control Circuit High”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic.
How is a p0004 DTC related to a fuel pump?
These high pressure fuel pumps have a low pressure side and high pressure side, and a fuel volume regulator which controls the pressure. For this P0004 code, it refers to an electrical reading that is above expected parameters. This code is related to P0001, P0002, and P0003. Symptoms of a P0004 DTC may include:
What does p0004 mean in a fuel pump?
It’s job is to increase the fuel pressure for the very high pressure needed at the fuel rail for the injectors. These high pressure fuel pumps have a low pressure side and high pressure side, and a fuel volume regulator which controls the pressure. For this P0004 code, it refers to an electrical reading that is above expected parameters.
What is the diagnostic code for fuel volume regulator?
P0004 is a diagnostic trouble code (DTC) for “Fuel Volume Regulator Control Circuit High”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
What should I do if I have a p0004 fault code?
The most common procedure to repair the P0004 code are 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.
What is the code for a fuel pump?
This code relates to the the electrical system as part of the fuel volume regulator system. Automotive fuel systems consist of many components, the fuel tank, fuel pump, filter, lines, injectors, etc. One component in high pressure fuel systems is a high pressure fuel pump.
