Maintenance
1. Locate and disconnect the mass
air flow sensor electrical connector
on the air outlet tube.
2. Reposition the locking clip on the
connector (connector shown from
below for clarity). Squeeze the
connector and pull it off the air
outlet tube.
3. Clean the area around the air
tube-to-air cover connection to
prevent debris from entering the
system. Loosen the bolt on the air
tube clamp so the clamp is no
longer snug to the air tube. It is not
necessary to remove the clamp
completely.
4. Pull the air tube off the air
cleaner housing.
