Is the continuity OK?
11)After repairing the trouble, clear the DTC using SDS tool.
(Refer to the SDS operation manual for further details.)
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 B/G wire
and B/Br wire, when idling condition.
$ HO2 sensor output voltage at idle speed:
0 – 1.0 V (

4) If OK, then remove the lower leg shield (#AN650K3 9-10)
and pinch the PAIR hose

5) Measure the HO2 sensor output voltage while holding the
engine speed at 5 000 r/min.
