What this code means

Common causes

  • VLOM (valve lifter oil manifold) stuck
  • Low oil pressure to lifters
  • Collapsed deactivation lifter
  • Oil passage blockage

Diagnostic steps

  1. Read cylinder deactivation status PIDs
  2. Command deactivation on/off with scan tool
  3. Check oil pressure at VLOM
  4. Test deactivation solenoid resistance
