7) Remove the left frame upper cover. (!VL1500 Service
Manual 6-3) and disconnect the ECM coupler.
8) Check the continuity between W/G wire A and terminal 7.
9) Also, check the continuity between B/Br wire B and terminal D.
" HO2S 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?
YES Go to Step 2. (When indicating C44/P0130:)

NO
open.
10)After repairing the trouble, clear the DTC using SDS tool.

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:
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:
# 09900-25008: Multi-circuit tester set
09900-25009: Needle pointed probe set
* Tester knob indication: Voltage (+)
0.4 V and less (+ W/G – - B/Br)
0.6 V and more (+ W/G – - B/Br)
