      *a	Inlet Air Temperature Sensor

      Disengage the 10 claws and 10 guides to remove the 2 No. 1 hybrid vehicle battery cover ducts from the HV battery.

      CAUTION:

      Be sure to wear insulated gloves and protective goggles.

      Note

      
      

      • Do not disconnect the inlet air temperature sensor from the No. 1 hybrid vehicle battery cover duct.

      • Do not apply excessive force to the inlet air temperature sensor wire harness when removing the No. 1 hybrid vehicle battery cover duct.

   7. 

      Disengage the 10 claws and 10 guides to remove the 2 hybrid vehicle battery cover exhaust ducts from the HV battery.

      CAUTION:

      Be sure to wear insulated gloves and protective goggles.

   8. Inspect HV battery:
