P2293 on Hyundai
Fuel Pressure Regulator 2 Performance
P2293 on Hyundai vehicles indicates fuel pressure regulator 2 performance. Au7o has documented this code across 1 Hyundai model — most commonly on Tucson. 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. Typical repair costs on Hyundai range from $450 to $800, depending on the specific model and root cause.
Common Causes of P2293
- •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
P2293 on Hyundai by Model
Hyundai Tucson(1 issue)
- High Pressure Fuel Pump Failure (GDI)2011-2018
The GDI high-pressure fuel pump on 2.4L Tucson models can fail, causing extended crank times, rough idle, and stalling. The pump cam follower wears prematurely, reducing fuel rail pressure below specification. This is especially common above 80,000 miles.

What does P2293 mean on Hyundai?▼
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 Hyundai specifically, this code is documented across 1 model.
What causes P2293 on Hyundai vehicles?▼
Common causes on Hyundai: 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.
