7) Disconnect the ECM coupler.
8) Check the continuity between W/G wire
and terminal

Step 2 (When indicating C44/P0130:)
1) Connect the ECM couplers 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 ( W/G – B/Br)
4) If OK, then remove the air cleaner box ( 5-14) and pinch
the PAIR hoses with proper hose clamps.
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)
