REMOVAL
1. Remove engine cover with power tool. Refer to EM-19, "INTAKE MANIFOLD COLLECTOR" .

This work is unnecessary when parts located forward of mass air flow sensor are removed/installed.
2. Remove air duct (inlet).
3. Disconnect mass air flow sensor harness connector.
4. Disconnect PCV hose.
5. Remove air cleaner case/mass air flow sensor assembly and air duct/resonator assembly disconnecting
their joints.

Add marks as necessary for easier installation.
6. Remove mass air flow sensor from air cleaner case.
CAUTION:
Handle mass air flow sensor with care.

Do not shock it.

Do not disassemble it.

Do not touch its sensor.
7. Remove resonator in fender, lifting left fender protector.
INSTALLATION
Note to the following, and install in the reverse order of removal.

Align marks. Attach each joint. Screw clamps firmly.

To position air cleaner case, refer to EM-18, "Changing Air Cleaner Filter" .
Changing Air Cleaner FilterABS004U1
INSPECTION
Check status (fouling, damage, etc.) of air cleaner filter at power duct
hole.
REMOVAL
Removal in the order below.
1. Remove air duct (inlet) from air cleaner case.
2. Disconnect harness connector from mass air flow sensor.
3. Loosen clamp bolts of air hose.
4. Remove mounting bolts for air cleaner case. Remove air cleaner
case/mass air flow sensor/air hose assembly.
5. Unclip and open air cleaner case, and remove air cleaner filter.
INSTALLATION
Note to the following, and install in the reverse order of removal.

If grommet at bottom of air cleaner case comes off together with
air cleaner case, fix it to vehicle before installation.

Look at internal bottom face through power duct hole, and posi-
tion air cleaner case with resonator upper end circle and air
cleaner case round hole aligned. Then push air cleaner case
straight down.

At this time, check by hand if protrusion at bottom of air cleaner
case has been inserted into grommet on vehicle side.

Clip power duct with bulge on reverse side of lower end
engaged with air cleaner case.

REMOVAL
WARNING:
Perform the work when the exhaust and cooling system have completely cooled down.
1. Remove engine cover with power tool. Refer to EM-19, "
INTAKE MANIFOLD COLLECTOR" .
2. Remove air cleaner case and air duct. Refer to EM-17, "
AIR CLEANER AND AIR DUCT" .
3. Remove front and rear engine undercover and front cross bar with power tool.
4. Disconnect heated oxygen sensors 2 (bank 1 and bank 2) harness connectors.
5. Using heated oxygen sensor wrench (SST), remove heated oxy-
gen sensors 2 (bank 1 and bank 2).
CAUTION:

Be careful not to damage heated oxygen sensor.

Discard any heated oxygen sensor which has been
dropped from a height of more than 0.5 m (19.7 in) onto a
hard surface such as a concrete floor; replace with a new
sensor.
