Inspection and Verification

NOTE: This service information provides mechanical diagnosis of the turbocharger assembly. If there is a Malfunction Indicator Lamp (MIL) illuminated, or Diagnostic Trouble Codes (DTCs) are present, these should be diagnosed prior to performing turbocharger mechanical diagnosis.
  1. For PCM  Diagnostic Trouble Codes (DTCs),

    or REFER to: ELECTRONIC ENGINE CONTROLS - 2.0L EcoBoost (184kW/250PS) - MI4 .

    See MIL Code List. For driveability symptoms without Diagnostic Trouble Codes (DTCs), Refer to ENGINE CONTROLS - SYMPTOM CHARTS (EXCEPT DIESEL & HYBRID) (SECTION 3) .

  2. Verify the customer concern.
  3. Visually inspect for obvious signs of mechanical or electrical damage.

SYMPTOM CHART

Symptom Possible Sources Action
  • Loss of power/performance
  • Clogged Air Cleaner (ACL) element
  • INSTALL a new Air Cleaner (ACL) element. TEST the system for normal operation.
  • Loose connections or damage to air intake hoses and tubes
  • TIGHTEN the hose clamps. INSPECT for damage and REPAIR as necessary.
  • Malfunctioning fuel system
  • Poor fuel quality
  • DRAIN and FILL with fresh fuel.
  • Engine wear (piston rings, valve guides)
  • REPAIR as required.
  • Turbocharger turbine or compressor wheel damage
  • Damaged exhaust or exhaust leaks at turbocharger housing
  • INSPECT for leaks. Leaks can usually be detected audibly or visually, by a discoloration caused by escaping hot exhaust gases. REPAIR as required.
  • Malfunctioning turbocharger bypass valve
  • Obstructed wastegate actuator linkage
  • INSPECT the turbocharger wastegate linkage for obstructions. REPAIR as required.
  • Damaged wastegate actuator linkage
  • INSPECT the turbocharger wastegate linkage for damage. INSTALL a new turbocharger as necessary.
  • Wastegate actuator operation
  • PCM  - Diagnostic Trouble Codes (DTCs)
Symptom Possible Sources Action
  • Excessive oil consumption
  • Incorrect type or grade of oil
  • DRAIN and FILL with specified oil.
  • Oil in the cylinder head to turbocharger flange
  • REPAIR as required.
  • Clogged Air Cleaner (ACL) element
  • INSTALL a new Air Cleaner (ACL) element. TEST the system for normal operation.
  • Blocked or restricted turbocharger oil drain tube
  • INSPECT the turbocharger oil drain tube. REPAIR as necessary.
  • Damaged or collapsed air intake hoses and tubes
  • TIGHTEN hose clamps. INSPECT for damage and REPAIR as necessary.
  • Damaged exhaust or exhaust leaks at turbocharger housing to cylinder head
  • INSPECT for leaks. Leaks can usually be detected audibly or visually, by a discoloration caused by escaping hot exhaust gases. REPAIR as required.
  • Turbocharger oil seals leaking
  • Damaged crankcase ventilation system
  • Visually INSPECT the crankcase ventilation system. REPAIR as necessary.
Symptom Possible Sources Action
  • Excessive noise
  • Turbocharger compressor air intake pipe leaking
  • REPAIR or INSTALL a new pipe as required.
  • Loose connections or damage to air intake hoses and tubes
  • TIGHTEN hose clamps. INSPECT for damage and REPAIR as necessary.
  • Air leaks at turbine housing, blown joints or damaged exhaust
  • INSPECT for leaks. Leaks can usually be detected audibly or visually, by a discoloration caused by escaping hot exhaust gases. REPAIR as required.
  • Carbon build up in the turbine housing causing contact with turbine wheel
  • Turbocharger imbalance due to foreign object/damage
  • REPAIR as required.
  • Turbine bearing failure
  • Inoperative turbocharger bypass valve
Symptom Possible Sources Action
  • Engine emits excessive smoke (black/blue/white)
  • Clogged Air Cleaner (ACL) element
  • INSTALL a new Air Cleaner (ACL) element. TEST the system for normal operation.
  • Incorrect type or grade of oil
  • DRAIN and FILL with specified oil.
  • Blocked or restricted turbocharger oil drain tube
  • INSPECT the turbocharger oil drain tube. REPAIR as necessary.
  • Damaged/restricted or leaking turbocharger compressor air intake pipe
  • REPAIR or INSTALL a new pipe as required.
  • Engine wear (piston rings, valve guides)
  • REPAIR as required.
  • Plugged crankcase ventilation system
  • Visually INSPECT the crankcase ventilation system. REPAIR as necessary.
  • Turbocharger oil seals leaking
