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
• Exhaust Leak (sounds strange, but check for one!)

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
• Fix exhaust leak if one is found.

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 *
  • (* always refer to repair manuals for specific values for your engine)

• 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.
  • TFSI - Oil leak - TFSI - Oil leak - Not a VCDS related question? or is it?
