Left bank heated oxygen sensor (rear)

1. Disconnect the heated oxygen sensor connector and

connect special tool MB991316 to the connector on the
heated oxygen sensor side.

2. Measure the resistance between terminal No. 1 (red clip)

and terminal No. 3 (blue clip) on the heated oxygen sensor
connector.

Standard value: 11

− 18 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.
6. Connect a digital voltage meter between terminal No. 2

(black clip) and terminal No. 4 (white clip).

7. Measure the output voltage of the heated oxygen sensor

under the following driving.

• Transaxle: 2 nd

• Drive with wide open throttle

• 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 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 Manifold

.

Right bank side (number 1, 3, 5 cylinders)

1. Disconnect the intermediate connector B-21.

2. Measure the resistance between the injector intermediate

connector terminals.

Standard value:

3. Connect the injector intermediate connector.

.

Left bank side (number 2, 4, 6 cylinders)

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.

<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

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.

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)]

3. If resistance is outside the standard value, replace the

throttle body assembly.

ENGINE OIL CONTROL VALVE CHECK

M1131053200456

Required Special Tools

• MB991658: Test Harness

.

Checking the Operation Sound

1. Disconnect the 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 engine oil control

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

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

oil control valve.

.

Checking the Coil Resistance

No. 2 of the connector at the 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

engine oil control valve.
