5. Use a jumper wire to connect terminal 1 (red clip) of
the oxygen sensor connector to the battery (+) terminal
and terminal 3 (blue clip) to the battery (-) terminal.
Caution
Be very careful when connecting the jumper wire;
incorrect connection can damage the oxygen sensor.
6. Connect a digital voltage meter between terminal 2 (black
clip) and terminal 4 (white clip).
7. While repeatedly racing the engine, measure the oxygen
sensor output voltage.
Standard value:
Engine
Oxygen sensor
output voltage
Remarks
When
racing the
engine
0.6 - 1.0 V
If you make the air/fuel ratio
rich by racing the engine
repeatedly, a normal oxy-
gen sensor will output a
voltage of 0.6 - 1.0 V.
8. If the sensor is defective, replace the oxygen sensor.
NOTE
For removal and installation of the oxygen sensor, refer
to GROUP 15 - Exhaust Pipe and Main Muffler.
<Oxygen sensor (rear)>
1. Disconnect the oxygen sensor connector and connect
the special tool (test harness set) to the connector on
the oxygen sensor side.
2. Make sure that there is continuity (11 - 18
W
at 20
_
C)
between terminal 1 and terminal 3 on the oxygen sensor
connector.
3. If there is no continuity, replace the oxygen sensor.
NOTE
(1) If the MUT-
II
does not display the standard value
although no abnormality is found by the above
mentioned continuity test and harness check, replace
the oxygen sensor (rear).
(2) For removal and installation of the oxygen sensor,
refer to GROUP 15 - Exhaust Pipe and Main Muffler.
