Removal Procedure
- Disconnect the mass air
flow/intake air temperature (MAF/IAT) sensor electrical connector.
- Loosen the intake air duct clamp at the throttle body.
- Remove the bolts retaining the upper housing cover to the lower
housing.
- Remove the upper housing cover and air intake duct from the throttle
body and lower housing.
- Remove the powertrain control module (PCM) and connector assembly
from the lower housing.
- Pull upwards to remove
the lower housing from the locating pins.
Notice:
| • | Handle the MAF sensor carefully. |
| • | Do not drop the MAF sensor in order to prevent damage to the MAF
sensor. |
| • | Do not damage the screen located on the air inlet
end of the MAF. |
| • | Do not touch the sensing elements. |
| • | Do not allow solvents and lubricants to come in contact with the
sensing elements. |
| • | Use a small amount of a soap based solution in order to aid in
the installation. |
- If replacing the upper housing cover, be sure to transfer the air intake
duct and MAF/IAT sensor to the replacement housing cover.
Installation Procedure
- Align the lower housing
to the front locating pin.
- Gently push downward to secure the lower housing to the rear locating
pins.
- Install the PCM and connector
assembly to the lower housing.

Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
- If replacing the
upper housing cover, transfer the MAF/IATsensor, intake air ducting, and the
clamps to the replacement cover.
Tighten
Tighten the clamp to 3 N·m (27 lb in).
- Install the upper housing cover and air intake duct assembly to
the throttle body.
Tighten
Tighten the clamp to 3 N·m (27 lb in).
- Install the upper housing cover to the lower housing.
Tighten
Tighten the bolts to 4 N·m (35 lb in).
