Caution:
– The fresh-air duct valve position sensor cannot be removed as single unit. When replacing the fresh-air duct valve position sensor, replace it together with the fresh-air duct as a single unit.
– IAT sensor No.1 is built into the MAF sensor. When replacing IAT sensor No.1, replace MAF sensor/IAT sensor No.1.

1. Disconnect the negative battery terminal.
2. Disconnect the MAF/IAT sensor No.1 connetor.
3. Remove the MAF sensor/IAT sensor No.1.
