Code P008A Lincoln Description

The Fuel Rail Pressure (FRP) Sensor is a diaphragm strain gauge device. The FRP sensor measures the pressure difference between the fuel rail and atmospheric pressure. The FRP sensor is located on the fuel rail and provides a feedback signal to indicate the fuel rail pressure to the Powertrain Control Module (PCM). The PCM uses the FRP signal to command the correct injector timing and pulse width for correct fuel delivery at all speeds and load conditions. The PCM regulates the fuel rail pressure by controlling the fuel volume regulator. This Diagnostic Trouble Code (DTC) is set when the low pressure fuel system pressure falls below an expected threshold.
