P2293 on Ford by model: symptoms, diagnosis and fix
The 2011-2016 6.7L Power Stroke uses a Bosch CP4.2 high-pressure fuel injection pump that is fundamentally incompatible with North American diesel fuel specifications. US diesel fuel has lower lubricity than European fuel, and the CP4 pump relies on fuel for internal lubrication. Over time, the CP4 pump's internal metal components grind and generate metal shavings that are distributed throughout the entire high-pressure fuel system at 30,000+ PSI. Metal contamination destroys all downstream injectors, fuel rails, and low-pressure system components. A class action lawsuit filed against Ford alleges the company knew the CP4 was incompatible with US fuel. Catastrophic failure can occur as early as 80,000-120,000 miles and requires complete fuel system replacement costing $8,000-$15,000.
Common Symptoms
- Loss of power during acceleration
- Engine hesitation and stumbling under load
- Hard start or no-start condition
- Smoke from exhaust (black or white)
- Check engine light with fuel system pressure codes
- Loud ticking or knocking from injector area
- Fuel rail pressure too low codes (P0087, P0191)
- Complete engine shutdown on the road
How to Fix
Complete fuel system replacement required: CP4 pump, all 8 injectors, high-pressure fuel rails, low-pressure pump, fuel filter housing, all fuel lines (metal contamination spreads everywhere). Ford kit EC3Z-9B246-C covers the repair for some years. Total cost $8,000-$15,000. Prevention: add diesel fuel lubricity additive (Stanadyne Performance Formula, Hot Shots Secret DIESEL EXTREME) at every fill-up. Some owners install a CP3 conversion pump kit (eliminates the CP4 with a more reliable Bosch CP3).

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 $15,000 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.
