The P0002 code is assigned to the circuit that is connected to your fuel pressure regulator. It can also refer to other codes, e.g. E.g; P0001, P0003 or P0004.
P0002 is a generic OBD-II code that indicates a problem with reading engine control module (ECM) signals from your fuel pressure regulator on your fuel rail mounted on the engine.
The ECM regulates the fuel pressure from your fuel pump that flows to your engine via this circuit and receives information about your actual fuel pressure. If the computer detects a pressure that is not sent to the fuel pump, it sets a Check Engine Light. The code affects fuel consumption and may damage the engine.
The range / performance code of the fuel quantity regulator can have several causes:
The P0002 code generates a Check Engine Light on the dashboard / dash and probably has the following effects:
The most common ways to repair the P0002 code are as follows:
Also diagnose the problem with the above device if the problem is present. Sensor signals should be analysed to determine where the problem is. If the signals are OK, we should go to the wiring, computer, or fuel system.
