The Ford Code P0002 is a diagnostic trouble code (DTC) associated with the fuel volume regulator control circuit range/performance. This code can be triggered when the output driver signal for the fuel volume control valve (FVCV) circuit moves outside the minimum or maximum limit for the commanded state. The causes of this code may vary, ranging from damaged fuel volume control valves to extremely high temperatures in the PCM power stage driver. To properly diagnose and fix the issue, it’s important to understand the different causes and potential solutions for the Ford Code P0002.

Causes and Solutions for Ford Code P0002
| Cause | Solution |
|---|---|
| Damaged fuel volume control valve | Replace the faulty FVCV |
| Faulty PCM power stage driver | Replace the PCM power stage driver |
| Incompatible fuel type | Replace the fuel with the correct type |
| Loose wiring | Check and tighten any loose wiring |
The Ford Code P0002 is one of many diagnostic trouble codes that can be triggered when something goes wrong with the vehicle’s fuel system. Acting quickly when this code is activated is important, as the underlying cause can be anything from a damaged fuel volume control valve to an incompatible fuel type. You can quickly identify and fix the issue by understanding the causes and potential solutions for the Ford Code P0002.
Damaged Fuel Volume Control Valve
The most common cause for the Ford Code P0002 is a damaged fuel volume control valve (FVCV). This valve is responsible for regulating the fuel pressure in the fuel system. When it becomes damaged, it can cause the output driver signal to move outside the minimum or maximum limit. To fix the issue, the FVCV will need to be replaced.
Faulty PCM Power Stage Driver
Another potential cause for the Ford Code P0002 is a faulty Powertrain Control Module (PCM) power stage driver. This component is responsible for controlling the fuel volume, and when it fails, it can cause the output driver signal to move outside the minimum or maximum limit. The PCM power stage driver will need to be replaced to fix the issue.

Incompatible Fuel Type
In some cases, the Ford Code P0002 can be triggered by an incompatible fuel type. If the vehicle uses a fuel type that is incompatible with the fuel system, it can cause the output driver signal to move outside the minimum or maximum limit. The fuel type will need to be replaced with the correct one to fix the issue.
Loose Wiring
The Ford Code P0002 can also be triggered by loose wiring in the fuel system. If the wiring becomes loose, it can cause the output driver signal to move outside the minimum or maximum limit. The wiring should be checked to fix the issue, and any loose connections should be tightened.
