Code P0088 Ford Description

The Fuel Pump (FP) Assembly contains the fuel pump and sender assembly. The fuel pump is located inside the FP assembly reservoir and supplies fuel through the FP assembly manifold to the engine and FP assembly jet pump. The jet pump continuously refills the reservoir with fuel, and a check valve located in the manifold outlet maintains system pressure when the fuel pump is not energized. The Powertrain Control Module (PCM) regulates the fuel rail pressure by controlling the fuel volume regulator. This Diagnostic Trouble Code (DTC) is set when the PCM is no longer capable of maintaining the fuel pressure within the calibrated parameters.
