Where is the fuel volume regulator control circuit?

Where is the fuel volume regulator control circuit?

What the P0001 code means. P0001 is the OBD-II generic code describing an issue with the circuit which runs from your engine computer (ECM) to your fuel pressure regulator on your fuel injection rail on your engine. The ECM regulates your fuel pressure from your fuel pump going to your engine through this circuit.

How do I fix code P0002?

The most common procedure to repair the P0002 code are as follows:

  1. Connect a professional scan tool.
  2. Check for any other fault codes.
  3. Analyze scan tool data from the ECM.
  4. Road test the vehicle while analyzing the scan tool data from the ECM.
  5. Check to see if the P0002 code returns.
  6. Inspect all of the items listed above.

What is a fuel volume control regulator?

The fuel volume control valve (otherwise known as a fuel volume control regulator) regulates the volume of fuel produced by the injection pump. The fuel volume control valve (FVCV) is controlled by a solenoid.

How do you fix a P0001 fuel volume regulator control circuit open?

How to diagnose and repair P0001

  1. Perform a preliminary inspection. Sometimes P0001 can pop up intermittently.
  2. Check the FVCV solenoid. Typically, the next thing a technician will do is check the FVCV solenoid.
  3. Check the circuit.
  4. Check the fuel pressure sensor.
  5. Check the PCM.

What does p0001 mean on a fuel volume regulator?

Error Code P0001 shows up when there’s an electrical problem that causes the fuel volume regulator to malfunction and open. It’s quite an unusual problem and likely intermittent.

What is the trouble code for a fuel pressure regulator?

P0001 trouble code definition. 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.

How do you open a fuel volume regulator?

Disconnect the FVCV connector and touch one end of a test light to the B+ pin. Connect the test light clamp to the battery negative post. The test light should illuminate. If it does not, there is problem in the power supply circuit and you will need to consult the factory wiring diagram.

Where is the fuel volume control valve located?

The fuel volume control valve (FVCV) is found on high pressure pump on most modern common rail diesel engines. It regulates the volume of fuel from the internal transfer pump to the high pressure pumping components. The valve adjusts the low pressure side of the system to meet the demands of the engine.
