OBD-II trouble code
P0002: Fuel Volume Regulator Control Circuit Range/Performance
SAE J2012: fuel volume regulator control circuit range/performance. The signal is in a readable span and does not match the condition this monitor uses. On the 2016 Ford 6.7L and 3.2L diesel summary, and on the 2016 F-450 diesel chart, that condition is powerstage temperature above 170°C, not a restricted fuel filter.

What does P0002 mean?
Range/performance means the circuit or the component is in range and still wrong for the conditions. It is not automatically a comparison of commanded volume with rail pressure. On the 2016 Ford 6.7L and 3.2L diesel OBD summary, P0002 sets when the volume-control powerstage driver is above 170°C (338°F). The 2017 summary (DOBDSM1701, revision 29 July 2016) marks that temperature test "(6.7L only)" and does not print a 3.2L threshold for it. The monitor does not use the rail-pressure sensor. Rail-pressure learning and over-pressure on that document are P000E and P228D. The low-pressure lift pump has its own codes, including P0627, P0628, P0629, and P0230–P0232. The 2016 F-450 diesel chart says the same thing: driver signal outside the commanded limit, aid is PCM powerstage temperature above 170°C, and the listed possible cause is a damaged fuel volume control valve. The chart sends you to pinpoint ME.
A restricted filter or a weak lift pump was not found as the enable condition for this Ford diesel monitor. Two neighboring procedures do check supply first, for other codes. Volkswagen technical bulletin 201502 (10 April 2015), for 2008–2015 CCTA/CBFA crank/no-start or rough running with P0087, checks low-pressure pump pressure before the high-pressure pump function test, and it says not to replace the high-pressure pump when actual rail pressure is within ±1 bar of 40 bar (580 psi) at idle. Detroit GHG17 publication 03 12-17 (March 2017), SPN 157/FMI 16, includes filter integrity and a compensation-pressure check of 620–758 kPa (90–110 psi) at 800 rpm before a quantity-control valve. Those limits belong to those codes and those engines. They are not a P0002 specification.
The EcoSport 2.0L chart does not list P0002. Its pressure codes are P0087, P0088, P00C6, and P053F, and those steps say to diagnose the regulator circuit codes first.
Common causes
- A fuel volume control valve that has driven the powerstage above 170°C, the cause listed on the 2016 F-450 diesel chart
- A connector or a control wire that pulls the driver outside the commanded limit on that chart
- A module powerstage, when pinpoint ME on that F-450 chart says the valve and the wiring are not the source of the temperature
- A repair aimed at a fuel filter or a lift pump, which this Ford diesel monitor does not use
- A gasoline direct-injection diagnosis copied from a diesel chart, or the reverse
- A high-pressure pump replaced on a P0087 complaint that the VW bulletin says to leave alone when idle rail pressure is within ±1 bar of 40 bar
Symptoms
- Check engine light with P0002
- A no-start or a limit on power if the volume valve has stopped metering
- The code stored with a powerstage-temperature fault on the Ford diesels named above
- Rail pressure that is a different code on the 2016 Ford diesel summary
- No confirmation from a new fuel filter, because that part is not in the Ford diesel monitor
- Companion codes for the lift pump, which stay with the lift pump
Diagnostic steps
- 1.Read the monitor description for this engine before you buy a filter or a pump. On the 2016 Ford 6.7L, 3.2L, and F-450 diesel charts, confirm powerstage temperature and follow pinpoint ME. The failed part that chart names, when the driver test points there, is the fuel volume control valve.
- 2.Do not open a high-pressure fitting to chase this code. Electrical checks stay on a closed system. Relieve the pressure only when the procedure you are in tells you to open a line.
- 3.Ignition off. Inspect the valve connector and measure the coil only against this engine's table. The 0.3–3.1 ohm operating-temperature table from the 2012 Ford gasoline pinpoint is for the engines that pinpoint lists. It is not the F-450 diesel test.
- 4.Separate supply problems that belong to other codes. A Ford diesel lift-pump code stays on that circuit. A VW CCTA/CBFA with P0087 follows bulletin 201502, including the 40 bar idle check, and that bulletin is not a P0002 procedure.
- 5.Replace the valve or the pump only when the pinpoint says the part is damaged. On the gasoline pages that replace the whole pump for a coil fault, the part is the pump. On the F-450 chart the named part is the volume control valve.
- 6.Clear the code and rerun the monitor the chart uses. A filter that was not in the monitor is not the confirmation.
Repair cost
$2,600 – $4,000 (diesel injection pump replacement)
The only parts-and-labor pump total found for this family is RepairPal's diesel injection pump replacement, $2,630–$4,034, updated 3 September 2026. The printed pair rounds it. Use it when the sold part is that pump. The 2016 F-450 chart's named part, when the driver test points there, is the fuel volume control valve, and no shop estimator priced that valve alone. A fuel filter and a lift pump are not this Ford diesel monitor and are not given a price here. The 2012 Ford gasoline pinpoint's fuel-injection pump is a different part from RepairPal's diesel injection pump page.

DIY vs shop
This is an advanced DIY job. It typically requires specialty tools, scan-tool access, lifting equipment, or careful sequencing to avoid causing new failures. Plan for extended downtime and have a backup vehicle. Most owners are better served by a shop that has done this repair before.
