P008A Jeep Code - Low Pressure Fuel System Pressure Too Low

Quick Answer

The Powertrain Control Module (PCM) provides the Fuel Rail Pressure Sensor with a 5-Volt supply and sensor ground and receives a signal voltage back from the Fuel Rail Pressure Sensor. Common causes include Low fuel level, Faulty Fuel Pressure Sensor, Fuel Pressure Sensor harness is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P008A Jeep Description

The Powertrain Control Module (PCM) provides the Fuel Rail Pressure Sensor with a 5-Volt supply and sensor ground and receives a signal voltage back from the Fuel Rail Pressure Sensor. This sensor signal voltage changes based on the pressure in the fuel rail. The PCM will light the MIL lamp immediately after the diagnostic runs and fails. During this time the customer may experience the power and/or speed derate. The PCM will turn off the MIL light after the diagnostic runs and passes in four consecutive drive cycles. The Diagnostic Trouble Code (DTC) will set when the Powertrain Control Module (PCM) detects that the Low-Pressure Fuel Delivery pressure is below a calibrated value for a calibrated amount of time.
