13A-189

CAUTION

Cover the hose connection with rags to prevent 
splash of fuel that could be caused by some 
residual pressure in the fuel pipe line.

2. Remove the fuel high-pressure hose at the 

delivery pipe.

3. Remove the injector.

4. Assemble the special tool called injector test set 

(MB992076) as shown in the figure according to 
the following procedure.

a. Disconnect the injector mounting hose.
b. Remove the adapter for mounting injector and 

attach the special tool Injector test nipple 
(MB992088) instead.

c. After attaching the injector on the special tool 

Injector test nipple (MB992088), secure it with the 
special tool injector holder (MB992184).

5. Mount the injector test set (MB992076) prepared 

with the special tool hose adapter (MB992001) 
onto the fuel high-pressure hose.

6. Connect the M.U.T.-III to the diagnosis connector.

7. Turn the ignition switch to the ON position. (But do 

not start the engine.)

8. Select "Item No. 9" of the M.U.T.-III actuator test 

to drive the fuel pump.

9. Connect the special tool Injector test harness 

(MB991607) between the injector and battery to 
drive the injector.

10.Check each injector for spray conditions. The 

condition can be considered satisfactory unless it 
is extremely poor.

11.Stop the actuation of the injector, and check for 

leakage from the injector nozzle.

Standard value: 1 drop or less per minute

12.After turning the ignition switch to the "LOCK" 

(OFF) position, remove the M.U.T.-III.

13.Actuate the injector until it does not spray fuel any 

longer, then drain the fuel inside the special tool.

14.Remove the special tool.

15.When the spray condition is extremely poor or 

any fuel leaks from the injector nozzle, replace the 
injector.

16.Replace the injector and fuel high-pressure hose 

in the original places.

THROTTLE VALVE CONTROL SERVO 
CHECK

M1131051001631

OPERATION CHECK

WARNING

When checking the throttle valve operation, 
never insert fingers into the throttle valve. 
The extremely strong power of the throttle 
valve motor might trap and injure fingers.

1. Remove the air intake hose from the throttle body 

assembly.

2. Turn the ignition switch to the ON position.

3. Verify that the throttle valve opens or closes 

according to the accelerator pedal operated.

CHECK THE COIL RESISTANCE

WARNING

When touching the throttle valve, surely shut 
off the driving circuits of the throttle valve. In 
the event that the throttle valve is operated, a 
finger might be injured as the result of being 
caught by the throttle valve.

Equipment side connector

Electronic-controlled
throttle valve

1. Disconnect the electronic-controlled throttle valve 

connector.

2. Measure the resistance between terminal No. 1 

and No. 2 of the electronic-controlled throttle 
valve connector.

Standard value: 0.3 

− 80 Ω (at 20°C)

NOTE: If the measured resistance deviates from the 
standard value, fully open the throttle valve with your 
finger more than five times, then check the result 
again.
If the throttle valve control serve is not used for an 
extended period of time, the resistance may be 
increased as a result of internal forming of oxide film. 
Therefore, it means that the oxide film can be 
removed through a self cleaning capability of the 
throttle valve control servo, if forcibly moved.

3. If the resistance deviates from the standard value, 

replace the throttle body assembly.

1. Disconnect the inlet oil feeder control valve 

connector.

CAUTION

To prevent the coil from burning, keep the dura-
tion of the voltage application as short as possi-
ble.
2. Make sure that the inlet oil feeder control valve 

generates a tick sound when the battery voltage is 
applied between the connector terminals at the 
inlet oil feeder control valve side.

RESISTANCE BETWEEN TERMINALS

1. Disconnect the inlet oil feeder control valve 

connector.

2. Measure the resistance between the terminals of 

the connector at the inlet oil feeder control valve.

Standard value: 6.9 

− 7.9 Ω (at 20°C)

3. If the resistance deviates from the standard value, 

replace inlet oil feeder control valve.
