IMPORTANT:
Take care when handling the mass air flow/intake air temperature (MAF/IAT) sensor. Do not dent, puncture, or otherwise damage the honeycell located at the air inlet end of the MAF/IAT. Do not touch the sensing elements or allow anything including cleaning solvents and lubricants to come in contact with them. Use a small amount of a non-silicone based lubricant, on the air duct only, to aid in installation. Do not drop or roughly handle the MAF/IAT sensor.
- Disconnect the MAF/IAT sensor electrical connector (1).
- Remove the air cleaner assembly. Refer to Air Cleaner Assembly Replacement .
- Loosen the clamp securing the MAF/IAT sensor to the air cleaner duct.
- Remove the MAF/IAT sensor bolts from the air cleaner assembly.
- Remove the MAF/IAT from the air cleaner.
