b) Turn lock lever to arrow direction until it stops.

4) Remove ECM (1) from its bracket by removing its

mounting bolts (2).

Installation
Reverse removal procedure noting the following:
• Connect connectors to ECM as follows.

a. Make sure that lock lever of ECM connector is

unlock position.

b. Insert ECM connectors to ECM until it stops with

unlocked lock lever.

c. Lock ECM connectors securely by pulling its lock

lever up.

Manifold Absolute Pressure (MAP) Sensor
Inspection

S6JB0A1316002

1) Disconnect connector from MAP sensor.
2) Remove MAP sensor from intake manifold.
3) Arrange 3 new 1.5 V batteries (2) in series (check

that total voltage is 4.5 – 5.0 V) and connect its
positive terminal to “Vin” terminal of sensor and
negative terminal to “Ground” terminal. Then check
voltage between “Vout” and “Ground”. Also, check if
voltage reduces when vacuum is applied up to 400
mmHg by using vacuum pump (3).
If check result is not satisfactory, replace MAP
sensor (1).

Output voltage (When input voltage is 4.5 – 5.5 V,
ambient temp. 20 – 30

°C, 68 – 86 °F)

4) Install MAP sensor securely.
5) Connect MAP sensor connector securely.

Electric Throttle Body Assembly On-Vehicle
Inspection

S6JB0A1316003

WARNING

!

Never touch throttle valve with finger while
ignition switch is turned ON and accelerator
pedal is depressed. Otherwise, injury may
result by pinching the finger between throttle
valve and throttle body housing.

CAUTION

!

• Do not disassemble electric throttle body

assembly.

• Do not expose electric throttle body

assembly to excessive shock like a
dropping it. If electric throttle body
assembly has been exposed to excessive
shock, it should be replaced.

• Be careful not to accrete a foreign material

(like dust and/or metallic particle) to the
throttle body housing and/or throttle valve.
Otherwise, the throttle body assembly is
breaking down by throttle valve accretion.

• Do not apply excessive moving force to

throttle valve for throttle valve operation
check and/or TP sensor performance
check.
Otherwise, the throttle body assembly is
breaking down by damaging the internal
resinous gear of throttle valve actuator.

Throttle Valve Visual Check

1) Remove air cleaner outlet hose (for J20 engine) or

air intake pipe (for M16 engine).

2) Check that there isn’t any foreign matter caught

between throttle valve and throttle body housing. If
there is, take it out after removing throttle body
referring to “Electric Throttle Body Assembly
Removal and Installation: For J20 Engine in Section
1D” or “Electric Throttle Body Assembly Removal
and Installation: For M16A Engine with VVT in
Section 1D”and clean inside of throttle body
thoroughly.

Throttle Valve Operation Check

1) Remove air cleaner outlet hose (for J20 engine) or

air intake pipe (for M16 engine).

2) Turn OFF ignition switch.
3) Move throttle valve with finger to its full open position

and check that it moves smoothly.

4) Move throttle valve with finger to its completely

closed position and check that it moves smoothly.

5) Take off finger from throttle valve (1) which is at full

open position and check that it moves smoothly by
its return spring and open spring force back to
default position (position where throttle valve is open
by 7

° (2) from completely closed position).

6) Take off finger from throttle valve (1) which is at

completely closed position and check that it moves
smoothly by its return spring and open spring force
back to default position.

If check result is not satisfactory, replace electric
throttle body assembly.

Electric Throttle Body Assembly Operation Check

1) Remove air cleaner outlet hose (for J20 engine) or

air intake pipe (for M16 engine).

2) Turn ON ignition switch.
3) Depress accelerator pedal gradually and check that

throttle valve moves smoothly until it opens fully.

4) Release accelerator pedal depressed in Step 3) and

check that throttle valve (1) moves back to default
position (position where throttle valve is open by 7

°

(2) from its completely closed position).

If check result is satisfactory, electric throttle body
system is in good condition. If check result is not
satisfactory, proceed to next step.

5) Perform “Accelerator Pedal Position (APP) Sensor

Assembly On-Vehicle Inspection”, “Throttle Actuator
(Motor) Check” and “Throttle Position Sensor
Performance Check”.
If check results are not satisfactory, replace electric
throttle body assembly.
If check results are satisfactory, wire circuit and/or
ECM are faulty.

Throttle Actuator (Motor) Check

1) Turn OFF ignition switch.
2) Disconnect connector from electric throttle body

assembly.

3) Measure resistance between “M1” terminal (1) and

“M2” terminal (2) of electric throttle body assembly.
If measured resistance is out of specified value,
replace electric throttle body assembly.
