P2293: Fuel Pressure Regulator 2 Performance
13 vehicles · 8 makes · $150-$18,000 repair
Most Reported On
P2293 is an OBD-II diagnostic trouble code meaning “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. This code is most commonly reported on 2019-2025 RAM 2500 (Big Horn, Laramie, Laramie Longhorn, Limited, Limited Longhorn, Lone Star, Rebel, SLT, Tradesman), 2011-2016 Ford F-250 Super Duty, and 2007-2012 MINI Cooper S, plus 10 other vehicles, with repair costs ranging from $150 to $18,000.

FAQ
What does P2293 mean?
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.
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?
Repair costs for P2293 range from $150 to $18,000, depending on the vehicle and root cause.
