Be careful not to touch the connector (resin section) with
the tool when removing and installing.

1.

Drain  engine  coolant,  then  remove  the  engine  coolant
temperature sensor.

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)

3.

If resistance deviates from the standard value greatly, replace
the sensor.

4.

Apply 3M™ AAD part number 8731 or equivalent to threaded
portion.

1.

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

2.

Make sure that there is continuity [4.5-8.0 ohms at 20°C (68°
F)] between terminal No. 1 (red clip) and terminal No. 3 (blue
clip) on the heated oxygen sensor connector.

3.

If there is no continuity, replace the heated oxygen sensor.

4.

Warm up the engine until engine coolant is 80°C (176°F) or
higher.

5.

Rev the engine for 5 minutes or more with the engine speed
of 4,500 r/min.

6.

Connect a digital voltage meter between terminal No. 2 (black
clip) and terminal No. 4 (white clip).

7.

While  repeatedly  revving  the  engine,  measure  the  heated
oxygen sensor output voltage.

REMARKS

When
revving
engine

0.6 - 1.0 V

If  you  make  the
air/fuel  ratio  rich
by  revving  the
engine
repeatedly,

 a

normal

 heated

oxygen

 sensor

will

 output

 a

voltage  of  0.6  -
1.0 V.

｠

Be  very  careful  when  connecting  the  jumper  wire;
incorrect connection can damage the oxygen sensor.

｠

Be careful the heater is broken when voltage of beyond
8V is applied to the oxygen sensor heater.

NOTE: 

If the sufficiently high temperature (of

approximate 400°C or more) is not reached although the
oxygen sensor is normal, the output voltage would be
possibly low although the rich air-fuel ratio. Therefore,
if the output voltage is low, use a jumper wire to connect
terminal No. 1 (red clip of special tool) and terminal No.
3 (blue clip of special tool) of the oxygen sensor with a
(+) terminal and (-) terminal of 8 V power supply
respectively, then check again.

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 .
