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:
0.3 V and less (

- 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 (

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.
