P117F - FUEL PRESSURE REGULATOR CONTROL EXCEEDED LEARNING LIMITS

Description:  The powertrain control module (PCM) monitors the operation of fuel pressure control valve and calculates parameters necessary for an ideal engine operation. These parameters are stored in the adaptive strategy table. The table is used as a correction factor when controlling engine operation and corrects for wear or aging of components. The DTC is set when the adaptive strategy has reached its minimum or maximum learning limits.
Possible Causes: 
  • Low pressure fuel system
  • Fuel pressure control valve
  • Fuel injectors internal leakage
Diagnostic Aids:  Use the high pressure fuel injection pump 4-pin inline connector to diagnose the fuel volume control valve and fuel pressure control valve.
