P2291 - Injector Control Pressure Too Low - Engine Cranking

WARNING: This page is about a different car, the 2012 Ford Pickup, 2012 Ford F550 Super Duty, 2012 Ford F450 Super Duty, and 2012 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
P2291 - INJECTOR CONTROL PRESSURE TOO LOW - ENGINE CRANKING

Description:  The powertrain control module (PCM) monitors the fuel rail pressure (FRP) during the engine cranking. If the FRP does not increase to the calibrated threshold while the engine is cranked this DTC is set.
Possible Causes: 
  • FRP sensor or circuitry
  • Fuel pump control - low pressure pump
  • Fuel pump control - high pressure fuel injection pump
  • Fuel volume control valve or circuitry
  • Fuel pressure control valve or circuitry
  • Poor fuel quality
Diagnostic Aids:  The FRP sensor, fuel pressure control valve and fuel volume control valve values can be monitored by accessing the FRP_A PID, the F_PCV and the F_VCV PID.
