2. With the temperature sensing portion of engine coolant 

temperature sensor immersed in hot water, check the 
resistance.

Standard value:

14 

− 17 kΩ [at -20°C (-4°F)]

5.1 

− 6.5 kΩ [at 0°C (32°F)]

2.1 

− 2.7 kΩ [at 20°C (68°F)]

0.9 

− 1.3 kΩ [at 40°C (104°F)

0.48 

− 0.68 kΩ [at 60°C (140°F)]

replace the sensor.

4. Apply LOCTITE 262 or equivalent to threaded portion.
5. With the special tool MB992042 (engine coolant 

temperature sensor wrench) tighten the engine coolant 
temperature sensor to the specified torque.

Tightening torque: 30 

± 9 N⋅m (22 ± 6 ft-lb)

HEATED OXYGEN SENSOR CHECK

M1131005003775

Required Special Tool:

• MB991658: Test Harness

.

Heated oxygen sensor (rear)

1. Disconnect the heated oxygen sensor connector and 

connect special tool MB991658 to the connector on the 
heated oxygen sensor side.

2. Measure the resistance between terminal No. 1 and terminal 

No. 2.

Standard value: 4.5 

− 8.0 Ω [at 20 °C (68 °F)]

3. If the resistance deviates from standard value, replace the 

heated oxygen sensor.

4. Warm up the engine until engine coolant is 80

°C (176°F) or 

higher.

5. Drive at 50 km/h (31 mph) or more for 10 minutes.

MULTIPORT FUEL INJECTION (MFI) <2.4L ENGINE>

13A-876

• Engine: 3,500 r/min or more

Standard value:

NOTE: If the temperature of sensing area does not reach 
the high temperature [of approximately 400

°

C (752

°

F) or 

more] even though the heated oxygen sensor is normal, the 
output voltage would be possibly low in spite of the rich 
air-fuel ratio. 
NOTE: When the vehicle is driven with high loads, the tem-
perature of the sensing area of the heated oxygen sensor is 
sufficiently high. Thus, it is not necessary to apply the volt-
age to the heater.

8. If the output voltage is not within the standard value, replace 

the heated oxygen sensor.
NOTE: For removal and installation of the heated oxygen 
sensor, refer to GROUP 15, Exhaust Pipe and Main Muffler

LINEAR AIR-FUEL RATIO SENSOR CHECK

M1131055300040

1. Disconnect the linear air-fuel ratio sensor connector and 

connect special tool MB991658 to the connector on the 
linear air-fuel ratio sensor side.

2. Measure the resistance between terminal No. 2 and terminal 

No. 3.

Standard value: 2.3 

− 4.2 Ω [at 20 °C (68°F)]

3. If the resistance deviates from standard value, replace the 

linear air-fuel ratio sensor.

NOTE: For removal and installation of the linear air-fuel ratio 
sensor, refer to GROUP 15, Exhaust Pipe and Main Muffler

INJECTOR CHECK

M1131005201988

<Checking the Operation Sound>

Using a stethoscope or long blade screwdriver, check the oper-
ation sound ("tick-tick-tick") of injectors during idling or during 
cranking. Check that as the engine speed increases, the fre-
quency of the operating sound also increases.
1. If the injector you are checking is not operating, you may 

hear the operating sound of the other injectors.

2. If no operating sound is heard from the injector that is being 

checked, check the injector drive circuit. If there is nothing 
wrong with the circuit, a defective injector or ECM is 
suspected.

<Checking the Coil Resistance>

.

1. Disconnect the injector connector.
2. Measure the resistance between injector side connector 

terminals 1 and 2.

Standard value: 10.5 

− 13.5 Ω [at 20°C (68°F)]

3. Connect the injector connector.

THROTTLE ACTUATOR CONTROL MOTOR 
CHECK

M1131051000810

.

<Operation Inspection>

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. Disconnect the air intake hose from the throttle body.
2. Set the ignition switch to the "ON" position.
3. Operate the accelerator pedal and confirm that the throttle 

valve is opening and closing accordingly.

.

<Checking the Terminal Resistance>

WARNING

If the throttle valve is operated in service, a finger 
might be injured as the result of being caught by the 
throttle valve. Make sure that the ignition switch is 
surely in "LOCK" (OFF) position before the service in 
order that the throttle valve cannot be operated.

1. Disconnect the throttle position sensor connector.

2. Measure the resistance between terminal No. 1 and No. 2.

Standard value: 0.3 

− 80 Ω [at 20°C (68°F)]

NOTE: If the measured resistance deviates from the stan-
dard value, fully open the throttle valve with your finger more 
then 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 resistance is outside the standard value, replace the 

throttle body assembly.

ENGINE OIL CONTROL VALVE CHECK

M1131053200605

Required Special Tools:

• MB991658: Test Harness

Intake engine oil control valve

.

<Checking the Operation Sound>

1. Disconnect the intake engine oil control valve connector.

CAUTION

To prevent the coil from burning, keep the duration of the 
voltage application as short as possible.
2. Check that the operation sound of the intake engine oil 

control valve can be heard when the positive battery voltage 
is supplied to the intake engine oil control valve. (Use the 
special tool MB991658 to connect terminal No. 2 of the 
intake engine oil control valve connector to the positive 
battery terminal and terminal No. 1 to the negative battery 
terminal.)

3. If the operation sound cannot be heard, replace the intake 

engine oil control valve.

.

<Checking the Coil Resistance>

1. Disconnect the intake engine oil control valve connector.
2. Measure resistance between terminal No. 1 and terminal 

No. 2 of the connector at the intake engine oil control valve 
side.

Standard value: 6.9 

− 7.9 Ω [at 20°C (68°F)]

3. If resistance is not within the standard value, replace the 

intake engine oil control valve.

Exhaust engine oil control valve

.

<Checking the Operation Sound>

1. Disconnect the exhaust engine oil control valve connector.
