P119A/004506 - Fuel Pressure Sensor (G247) : Malfunction

Possible Symptoms

  • Malfunction Indicator Light (MIL) active
  • Reduced fuel economy and engine performance

Possible Causes

  • Faulty Fuel Pressure Sensor (G247)
  • Wiring and/or Connector(s) from/to Fuel Pressure Sensor (G247)
  • Faulty HPFP
  • Faulty (leaking) fuel injector

Possible Solutions

  • Replace Fuel Pressure Sensor (G247)
  • Check Wiring and/or Connector(s) from/to Fuel Pressure Sensor (G247)
  • Replace HPFP
  • Check fuel injectors for leak-down

Special Notes

  • The Fuel Pressure Regulator Valve (N276) or Fuel Metering valve (N290) on the HPFP can fail.
    • (N276) Fuel Pressure Regulating Valve resistance should be approximately 1 to 5 Ω
    • (N290) Fuel Metering valve resistance should be approximately 0.8 to 5 Ω
  • If found with a TFSI engine and 16555/P0171/000369 - Fuel Trim; Bank 1: System Too Lean is also flagged, this could be caused by a failed rear main seal.
