2024年10月30日 · The P0004 code is a general powertrain issue that signals a problem with the fuel volume regulator control circuit, which directly affects how fuel is delivered and how the engine performs. When this code pops up, it means your fuel system isn’t regulating properly, leading to uneven fuel flow.

2022年2月7日 · If your vehicle logs a P0004 code, it means that the fuel volume regulator’s electrical readings have gone above the normal range, which can lead to performance issues. A failed fuel volume regulator solenoid as well as wiring issues are potential causes of a logged P0004 trouble code.

2023年4月10日 · - Diagnosing OBDII code P0004 typically involves checking the wiring and connections related to the fuel volume regulator control circuit, as well as testing the regulator itself for proper functioning.

A P0004 is not a very common trouble code and is more often seen on common rail diesel (CRD) and/or diesel engine, and gasoline direct injection (GDI) equipped vehicles. This code relates to the the electrical system as part of the fuel volume regulator system.

2016年6月2日 · 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.

P0004 is a generic OBD-II code indicating an issue with the engine control module (ECM) not reading signals from your fuel shut-off on your fuel injection rail mounted to your engine. The ECM uses the fuel shut-off valve to stop fuel from entering the engine when you turn it off.

2023年7月3日 · What does the P0004 code mean? The P0004 code is a generic powertrain code that indicates a problem with the fuel volume regulator control circuit. In simpler terms, it means that there is an issue with the fuel system of your car. The appearance of this code can be concerning, and it’s essential to understand what it means and how to fix it.
