What is the P0002 Fault Code and what does it mean? What does it signify?
The fuel system of your vehicle consists of several components, including the fuel tank, fuel pump and fuel filter, as well as fuel pipes, fuel injectors, and fuel pipes. Fuel pressure must be within the correct range to allow fuel injectors proper functioning. A fuel volume regulator, also known as a fuel control valve, controls fuel pressure on some vehicles, especially diesels. The PCM regulates the fuel volume and pressure through the control of the solenoid fuel volume regulator. When the PCM detects an issue with the fuel volume regulator circuit, a code P0002 will be set.
P0002 is not a common fault code. This fault code is most commonly found in common rail diesel (CRD), diesel engines, and gasoline direct injection vehicles (GDI). This code is often associated with the wiring that connects to the vehicle’s fuel pressure regulator.
Similar fault codes include P0001, P0003 or P0004.
What causes the P0002 fault code?
- – Defective fuel volume regulator
- – Defective fuel volume regulator solenoid
- – Circuit problems like loose or damaged connections and wiring
- – Defective fuel pump
- – Defective fuel pressure sensor
- – A PCM that is not working or requires a software upgrade
What are the symptoms for P0002 fault code?
- – Illumination for the check engine light
- – Reduced engine performance
- – Engine stalling during driving
- – Increased fuel consumption
- Engine not running
- – Exhaust smoke – White or black
- – Catalytic converter damage
How to Fix the P0002 Fault Code
- – Clear all codes first and then run a road test to verify if the code returns.
- – Wiring and connections should always be checked and fixed if P0002 is returned.
- – Replacing solenoid fuel volume regulator
- If it is defective, the voltage signal on the fuel volume regulator must be tested and should be replaced.
- – If it is defective, the fuel pressure sensor’s voltage signal should be checked and replaced.
How Serious Is the P0002 Fault Code
Fault code P0002 can affect your vehicle’s driving comfort. If it isn’t addressed quickly, it could cause serious damage to the engine and catalytic convert.
