THROTTLE BODY ASSEMBLY

REMOVAL AND INSTALLATION

M1131007701495

CAUTION

• When the throttle body assembly replacement is performed, use the M.U.T.-III to initialize the 

learning value (Refer to GROUP 00, Precautions Before Service 

− Initialization Procedure for 

Learning Value in MPI Engine 

P.00-20

).

• Do not loosen the fixing screws for the resin cover of throttle body assembly. If the screws are 

loosened, the sensor incorporated in the resin cover becomes misaligned and the throttle body 
can not work normally.

Pre-removal Operation
• Engine Cover Removal (Refer to GROUP 11A, Camshaft 

P.11A-17

)

• Engine Coolant Draining (Refer to GROUP 14, On-vehicle 

Service 

− Engine Coolant Replacement 

P.14-4

).

• Air Cleaner Assembly Removal (Refer to GROUP 15, Air 

Cleaner 

P.15-5

).

Post-installation Operation
• Air Cleaner Assembly Installation (Refer to GROUP 15, 

Air Cleaner 

P.15-5

).

• Engine Coolant Supplying (Refer to GROUP 14, On-vehi-

cle Service 

− Engine Coolant Replacement 

P.14-4

).

• Engine Cover Installation (Refer to GROUP 11A, Cam-

shaft

MULTIPORT FUEL INJECTION (MPI) <4A9>

13A-371

INSTALLATION SERVICE POINTS
>>A<< THROTTLE BODY GASKET 
INSTALLATION

Securely insert the throttle body gasket in the groove 
of the inlet manifold without causing any torsion or 
damage to the gasket. 

>>B<< SCREW INSTALLATION

CAUTION

Do not over-tighten. As the self-forming-type 
screw is used, the excessive torque can damage 
the inlet manifold threads.

>>C<< INITIALIZATION

When the throttle body is installed, removed or 
replaced, initialize the electronic-controlled throttle 
valve system according to the procedure below 
beforehand.

Turn the ignition switch from "ON" position to 
"LOCK" (OFF) position, and then hold "LOCK" 
(OFF) position for approximately 10 seconds or 
more.

ENGINE-ECU AND ENGINE-CVT-ECU

REMOVAL AND INSTALLATION

M1131025800031

CAUTION

• When the engine-ECU <M/T> or engine-CVT-ECU <CVT> replacement is performed, always refer to 

GROUP 54A, Ignition Switch 

− Encrypted Code Registration Criteria Table 

P.54A-8

.

• After the engine-ECU <M/T> or engine-CVT-ECU <CVT> is replaced, idling speed may be unstable 

because the MPI engine learning is not completed. To make it stable, make the system learn the 
idling (Refer to GROUP 00 

− Precautions before Service, Learning Procedure for Idling in MPI 

Engine 

P.00-21

).

INSTALLATION SERVICE POINT
>>A<< INITIALIZATION

When the engine-ECU <M/T> or engine-CVT-ECU 
<CVT> is removed, initialise the electronic-controlled 
throttle valve system according to the following pro-
cedure after installing the ECU.

Turn the ignition switch from "ON" position to 
"LOCK" (OFF) position, and then hold "LOCK" 
(OFF) position for approximately 10 seconds or 
more.
