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 P.15-16.

1.

Disconnect the heated oxygen sensor connector and connect
special tool MD998464 to the connector on the heated oxygen
sensor side.

2.

Make sure that there is continuity [11-18 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.

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).
