EXHAUST MANIFOLD AND THREE WAY CATALYSTPFP:14004
Removal and InstallationEBS00KND
REMOVAL
1. Remove heated oxygen sensors with the following procedure:
a. Disconnect harness connector of each heated oxygen sensor, and harness from bracket and middle
clamp.
b. Using heated oxygen sensor wrench (special service tool),
remove heated oxygen sensors.
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
one.
2. Remove exhaust front tube. Refer to EX-2, "
EXHAUST SYSTEM" .
3. Remove alternator. Refer to SC-13, "
CHARGING SYSTEM" .

5. Loosen nuts in reverse order as shown in the figure to remove
exhaust manifold and three way catalyst assembly.
NOTE:
Disregard No. 6 and 7 when loosening.
6. Remove gasket.
CAUTION:
Cover engine openings to avoid entry of foreign materials.
7. Remove exhaust manifold cover (lower) and three way catalyst cover from exhaust manifold and three
way catalyst assembly.
INSPECTION AFTER REMOVAL
Surface Distortion

Using straightedge and feeler gauge, check the surface distor-
tion of exhaust manifold and three way catalyst assembly mating
surface.

If it exceeds the limit, replace exhaust manifold and three way
catalyst assembly.
INSTALLATION
Note the following, and install in the reverse order of removal.
Exhaust Manifold

If stud bolts were removed, install them and tighten to the specified torque below.

Tighten nuts in numerical order as shown in the figure.
NOTE:
No. 6 and 7 mean double tightening of bolts No. 1 and 3.
Heated Oxygen Sensor
CAUTION:

Before installing a new heated oxygen sensor, clean exhaust system threads using heated oxygen
sensor thread cleaner and apply anti-seize lubricant (commercial service tool).

Do not over torque the heated oxygen sensor. Doing so may cause damage to the heated oxygen
sensor, resulting in the “MI” coming on.

Removal and Installation (QR20DE)EBS00KNH
CAUTION:
Do not remove or disassemble parts unless instructed as shown in the figure.
REMOVAL
1. Release fuel pressure. Refer to EC-49, "FUEL PRESSURE RELEASE" (WITH EURO-OBD) or EC-562,
"FUEL PRESSURE RELEASE" (WITHOUT EURO-OBD).
2. Remove air cleaner case upper, mass air flow sensor and air duct assembly. Refer to EM-16, "
AIR
CLEANER AND AIR DUCT" .
3. Disconnect quick connectors at engine side and vehicle side as
follows, and remove fuel feed hose.
CAUTION:
Disconnect quick connector by using quick connector
release (special service tool), not by picking out retainer
tabs.
NOTE:
There is quick connector for the engine side and for the vehicle
side, and they have different shapes. But disconnection is same
procedure. The following procedure shows the engine side.
a. Remove quick connector cap (engine side).
1. Fuel feed hose 2. Quick connector cap (engine side) 3. Quick connector cap (vehicle side)
4. Centralized under-floor piping 5. Sub-harness 6. Fuel tube protector
