INSPECTION (E-02,
19)
Remove the seat. (W7-4)
Disconnect the
H02
sensor coupler.
Remove the
H02
sensor unit.
I
Do not remove the H02 sensor while it is hot.
I
Be careful not to expose it to excessive shock.
Do not use an impact wrench while removing or
installing the H02 sensor unit.
Inspect the
H02
sensor and its circuit referring to flow table of
the malfunction code (C44).
Disconnect the
H02
sensor coupler.
Check the resistance between the terminals (white
-
white) of
the
H02
sensor.
Resistance: 4
-
5 R (at 23 "Cn3.4 OF)

g)
Tester knob indication: Resistance (R)
If the resistance is not within the standard range, replace the
H02
sensor with a new one.
NOTE:
*
Temperature of the sensor affects resistance value largely.
*
Make sure that the sensor heater is at correct temperature.
Connect the
H02
sensor coupler securely.
Installation is in the reverse order of removal.

Route the
H02
sensor lead wire into the frame.
Connect the
