Ford’s Code P0004 is an indication of fuel volume regulator control circuit high. This diagnostic trouble code is triggered when the output driver signal of the FVCV circuit moves beyond the minimum or maximum limit for what is commanded. This DTC can cause an engine crank no start condition, and if the engine does start and DTC P0001 is present, it can be an indication of an intermittent concern. It is important to understand the possible causes and possible solutions for Ford’s Code P0004 in order to fix the issue.
Causes and Solutions for Ford Code P0004
| Cause | Solution |
|---|---|
| Damaged Fuel Volume Control Valve Connector | Inspect and replace the connector |
| FVCV Circuit Open | Check the circuit and repair if necessary |
| Damaged Fuel Volume Control Valve | Replace the fuel volume control valve |
| Intermittent Concern | Check the voltage and inspect the FVCV circuit |
Ford’s Code P0004 is one of the most common diagnostic trouble codes that can appear in Ford vehicles. It is important to understand the possible causes and possible solutions for Ford’s Code P0004 in order to fix the issue and prevent further damage. Diagnosing and repairing the issue can be difficult and time consuming, but being aware of the issue and its potential solutions can help to identify and fix the issue more quickly.
Damaged Fuel Volume Control Valve Connector
One of the most common causes of Ford Code P0004 is a damaged or faulty fuel volume control valve connector. A damaged connector can cause the output driver signal of the FVCV to move beyond the minimum or maximum limit for what is commanded. In order to fix this issue, the connector should be inspected and replaced if necessary.
FVCV Circuit Open
Another cause of Ford Code P0004 is an open FVCV circuit. This can be caused by a faulty or damaged wiring harness or a bad connection. In order to fix this issue, the FVCV circuit should be checked and repaired if necessary.
Damaged Fuel Volume Control Valve
In some cases, Ford Code P0004 can be caused by a damaged or faulty fuel volume control valve. If the valve is damaged or faulty, it should be replaced in order to fix the issue.
Intermittent Concern
In some cases, Ford Code P0004 can be caused by an intermittent concern. This can be difficult to diagnose and can require checking the voltage and inspecting the FVCV circuit.
Conclusion
Ford Code P0004 is an indication of fuel volume regulator control circuit high. It is important to understand the possible causes and possible solutions for Ford Code P0004 in order to fix the issue and prevent further damage. Diagnosing and repairing the issue can be difficult and time consuming, but being aware of the issue and its potential solutions can help to identify and fix the issue more quickly.
