Step 2 (When indicating 44/P0130:)
1) Connect the ECM coupler and HO2 sensor coupler.
2) Insert the needle pointed probes to the HO2 sensor coupler.
3) Warm up the engine enough.
4) Measure the HO2 sensor output voltage between W/G wire
A
and Br/B wire
B
, when idling condition.

HO2 sensor output voltage at idle speed:
0.3 – 1.0 V (

5) If OK, 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 or 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.
