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).
