P2291 - INJECTOR CONTROL PRESSURE TOO LOW - ENGINE CRANKING

Description:  The DTC sets when the PCM does not detect any ICP during crank (long crank time).
Possible Causes: 
  • empty/low oil reservoir at crank

  • high-pressure oil system repair
  • ICP sensor
  • ICP sensor circuit concern
  • IPR valve
  • low engine oil level or incorrect viscosity
