17519/P1111 Oxygen sensor control; Bank 1: System too lean

Possible Causes

  • Mass Air Flow Sensors (G70) faulty
  • Intake Air System faulty/leaking (false Air)
  • Fuel Injector(s) faulty
  • Insufficient Fuel Delivery
  • Exhaust System leaking
  • Faulty O2 Sensor(s)

Possible Solutions

  • Check Mass Air Flow Sensors (G70)
  • Check Intake Air System for Leaks
  • Check Fuel Injector(s)
  • Check Fuel Delivery Including Pump and Filter
  • Check Exhaust System for Leaks
  • Check O2 Sensor(s) Adaptation Values (Before Clearing Faults: Fuel Trim Information)
