7) Disconnect the ECM coupler.
8) Check the continuity between W/G wire A and terminal 6.
9) Also, check the continuity between B/Br wire B and terminal B.

$ HO2 sensor lead wire continuity: Continuity (*)
# 09900-25008: Multi-circuit tester set
09900-25009: Needle pointed probe set
+ Tester knob indication: Continuity test (*)
Is the continuity OK?
Step 2 (When indicating C44/P0130:)
1) Connect the ECM coupler and HO2 sensor coupler.
2) Warm up the engine enough.
3) Measure the HO2 sensor output voltage between W/G wire
and B/Br wire, when idling condition.
$ HO2 sensor output voltage at idle speed:
0.4 V and less (+ W/G – - B/Br)
4) If OK, then pinch the PAIR hose 1 with a proper hose clamp.
5) Measure the HO2 sensor output voltage while holding the
engine speed at 5 000 r/min.
$ HO2 sensor output voltage at 5 000 r/min:
0.6 V and more (+ W/G – - B/Br)

' Tester knob indication: Voltage (()
When using the multi-circuit tester, do not strongly
touch the terminal of the ECM coupler with a needle
pointed tester probe to prevent the terminal damage
or terminal bend.
YES Go to Step 2. (When indicating C44/P0130:)
NO
W/G wire shorted to ground, or W/G or B/Br wire
open.
