P2293 on Ford by model: symptoms, diagnosis and fix
The 2011-2016 6.7L Power Stroke uses a Bosch CP4.2 high-pressure fuel pump, which is lubricated by the diesel fuel passing through it. When the pump wears internally, it sheds metal particles. The pump feeds fuel to the injectors at very high pressure, so those particles can be carried into the injectors, fuel rails, high-pressure lines and the return side of the system. A diesel parts seller describes some early CP4 failures as sudden ("grenade") failures that send debris through the whole fuel system, and says flushing and cleaning will not restore it. Owners have sued Ford over the pump. The lawsuits claim the CP4 design is fragile and incompatible with U.S. diesel fuel, which they describe as low in lubricity, and that Ford knew this and did not disclose it. Ford disputes that the pump is defective. It says the pump was adequately designed and tested, and that failures can come from causes such as contaminated fuel. In Droesser v. Ford (E.D. Mich., No. 2:19-cv-12365), the court certified classes in California, Louisiana, Ohio, Pennsylvania and South Carolina on September 30, 2026. The classes cover owners of 2011-and-later 6.7L trucks who paid out of pocket for a CP4 repair. That ruling does not find Ford liable, and there is no settlement, payment amount or claim process yet. Once metal has spread, the repair usually means replacing the pump, injectors, rails and lines. One diesel shop reports that dealer bills for this job routinely run $8,000 to $12,000.
Common Symptoms
- Loss of power during acceleration
- Engine hesitation and stumbling under load
- Hard start, or cranks but will not start
- Fuel rail pressure too low codes (P0087, P0191)
- Check engine light with fuel system pressure codes
- Metal particles found in the fuel filter
- Engine shutting off while driving
How to Fix
Check first: if the truck is hard to start, cranks but won't start, loses power, or sets a fuel rail pressure code, have the fuel filters checked for metal. A diesel shop advises cutting open the return filter and inspecting the media. Metal in the filter means the pump is failing or has failed. If metal is confirmed, Ford sells a complete Motorcraft fuel system contamination repair kit. The part number depends on the truck: - 2011-2014 trucks (build dates 2/22/2010 to 3/17/2014): EC3Z-9B246-C. It includes a CP4 pump, 8 injectors, both fuel rails, and the high-pressure and return lines. - 2015-2016 F-250/F-350 pickups: FC3Z-9B246-F. It includes the CP4 pump, injectors, both rails, fuel lines, and the fuel pressure regulator and sensor. It does not fit cab-chassis trucks. Confirm the right kit for your VIN with a Ford dealer. Online sellers list the kits at roughly $3,400 to $5,300, plus a refundable core charge and labor. One diesel shop reports that dealer bills for the full job routinely run $8,000 to $12,000. Coverage: you may be a member of the certified class in Droesser v. Ford if you bought your truck in California, Louisiana, Ohio, Pennsylvania or South Carolina, paid out of pocket for a CP4 repair, did not sign a dealer arbitration agreement, and have not already been reimbursed by Ford. No settlement or claim process exists yet, so keep all repair invoices. Risk reduction is up to the owner, and none of these are Ford repairs. Some owners add a diesel lubricity additive. Others fit an aftermarket "disaster prevention" kit, which is a return-line filter and bypass meant to contain debris. It does not stop the pump from failing. A third option is replacing the CP4 with a different pump, such as a Stanadyne DCR-style conversion.

Frequently asked questions
What does P2293 mean on a Ford?
P2293 stands for "Fuel Pressure Regulator 2 Performance." This code means the engine computer has detected that the fuel pressure regulator 2 isn't performing as expected, so the system can't maintain the correct fuel pressure under varying conditions. On many direct-injection and high-pressure systems, regulator 2 controls the high-side fuel pressure, and the computer compares commanded pressure to what the fuel pressure sensor actually reports. When the measured pressure drifts too far from the target, it sets this performance code, which can cause hard starting, rough running, hesitation, reduced power, or stalling. Causes typically include a faulty regulator or high-pressure pump, a fuel delivery restriction, or a pressure sensor problem. On Ford it is documented across 1 model: F-250 Super Duty.
What are the most common causes of P2293?
The most common causes of P2293 are: Faulty fuel pressure regulator (regulator 2), Failing high-pressure fuel pump, Faulty or out-of-range fuel rail pressure sensor, Clogged fuel filter or restricted fuel supply, Weak low-pressure (lift) pump feeding the high-pressure system, Leaking fuel injector bleeding off pressure, Wiring or connector fault to the regulator/pump, Air or contamination in the fuel system. The specific cause varies by vehicle.
How much does it cost to fix P2293 on a Ford?
Published repair estimates on Ford range from $8,000 to $12,000 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
