P149C - Fuel Volume Regulator Current Performance

DTC DESCRIPTION P149C - FUEL VOLUME REGULATOR CURRENT PERFORMANCE

Description:  This DTC sets when fuel volume control valve setpoint current is persistently higher than actual measured current.
Possible Causes: 
  • FVCV circuit short to voltage
  • FVCV circuit short to ground
  • Damaged fuel volume control valve
Diagnostic Aids:  The presence of this DTC may indicate that the vehicle is operating in derate mode and may experience a loss of power. After repair, the vehicle may still display a system warning message. Drive the vehicle until the system warning message has cleared from the instrument cluster message center. Check the harness for intermittent concerns, incorrect connections, routing, alterations and damage due to contact with other components.
