Diagnosis and Testing

Inspection and Verification

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

Visual Inspection Chart

Mechanical Electrical
  • Air cleaner element
  • Air cleaner intake pipe
  • Air cleaner outlet pipe
  • Charge air cooler (Vehicles with 1.6L Duratorq-TDCi (DV) Diesel engine)
  • Charge air cooler intake hose (Vehicles with 1.6L Duratorq-TDCi (DV) Diesel engine)
  • Charge air cooler outlet hose (Vehicles with 1.6L Duratorq-TDCi (DV) Diesel engine)
  • Mass air flow (MAF) sensor
  • Manifold absolute pressure (MAP) sensor (Vehicles with 1.6L Duratorq-TDCi (DV) Diesel engine)
