Injector Control Pressure Too Low — Engine Cranking

Understand P2291, common causes, and the right TOPDON scanner to diagnose it.

ICP below minimum during cranking — classic 6.0L/6.4L Ford no-start code.

Typowe objawy

  • Extended crank no-start
  • ICP reads low on scan tool

Typowe przyczyny

  • Failed HPOP
  • Injector stiction
  • ICP sensor fault
  • Low oil level

Jakiego skanera potrzebujesz?

Full-system scanner (engine, ABS, SRS, transmission, service resets)

Użyj danych na żywo i freeze frame przed wymianą części. Kody ABS, SRS i U zwykle wymagają skanera full-system.

Wskazówki diagnostyczne

  • Zapisz freeze frame, gdy pojawi się kod
  • Kasuj kod dopiero po usunięciu przyczyny
  • Sprawdź powiązane kody pending
  • Sprawdź, czy napięcie akumulatora jest powyżej 12,4 V przed podejrzeniem czujników
