What does it mean when the fuel volume regulator control circuit is open?

– P0001 : “Fuel Volume Regulator Control Circuit – Open”. 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.

How do I fix error code P0003?

The most common procedure to repair the P0003 code are as follows: Connect a professional scan tool. Verify the code exists. Check for any other fault codes which may be related to the issue, then clear the fault codes to see which fault codes return.

How can you tell if fuel pressure regulator is bad?

Symptoms Of A Bad Fuel Regulator

  1. Engine misfires/poor acceleration.
  2. Black smoke coming from the exhaust.
  3. Spark plugs appear black.
  4. Reduced fuel mileage.
  5. Gasoline in the vacuum hose.
  6. Engine backfires.
  7. Engine won’t crank.
  8. Excessive fuel pump noise.

Why does my fuel pump have an open code?

Depending on the needs of the driver, the control circuit is responsible for turning the pump on and off. An open condition within this circuit could also cause this code, so take note of this before proceeding with any diagnosis.

How can I tell if my fuel volume regulator is open?

Disconnect the FVCV connector and touch one end of a test light to the ground pin. Connect the test light clamp to the battery positive post. Crank the engine. If the PCM is grounding the circuit, the test light should flash. If it does not, there is either an open in the ground side of the circuit or problems with the PCM.

Where to check for no start fuel pump?

The first thing you want to do is check the fuse panel to see if the fuse is blown. If your car has two fuse panels than the one in the engine compartment; should be the correct one to check. The fuse panel or circuit box is usually located near the battery; and is a small black box with a removable lid.

How to test for resistance to ground on fuel pump?

Test for resistance to ground on the secondary (fuel pump) circuit, which should measure at least 4 Ω to 6 Ω. Go back to the short circuit section above. The primary circuit is grounded by the ECM, so you should check for ground when you turn the key to the “On” position or try to crank the engine.
