The P1154 code for Jeep indicates a Fuel Rail Pressure Malfunction, specifically that the rail pressure is too low. This means that there is an issue with the fuel system that is preventing the fuel rail pressure from reaching the necessary levels for proper engine performance. The fuel rail is responsible for supplying pressurized fuel to the fuel injectors, which then deliver the fuel to the engine cylinders for combustion. When the fuel rail pressure is too low, the engine may experience a variety of performance issues, including rough idling, hesitation, lack of power, and even stalling.

- Faulty fuel pump: A failing fuel pump may not be able to maintain the necessary fuel pressure in the rail.
- Clogged fuel filter: A dirty or clogged fuel filter can restrict fuel flow, leading to low fuel pressure.
- Fuel pressure regulator malfunction: A malfunctioning fuel pressure regulator may not be able to regulate the fuel pressure effectively.
- Fuel system leak: A leak in the fuel system can cause a loss of fuel pressure, resulting in low rail pressure.
