5-80 FI SYSTEM DIAGNOSIS
6) Disconnect the ECM coupler. (

.
8) Also, check the continuity between B/Br wire

Step 2
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 or
W/Bl wire and B/Br wire, when idling condition.
$
HO2 sensor output voltage at idle speed:
0.4 V and less (
+
W/G or W/Bl –
-
B/Br)
4) If OK, then pinch the PAIR hose
1
with a proper hose clamp.
5) Remove the fuel tank (
#
6-3) and frame head covers
(
#
9-6).
6) Measure the HO2 sensor output voltage while holding the
engine speed at 3 000 r/min.
$
HO2 sensor output voltage at 3 000 r/min:
0.6 V and more (
+
W/G or W/Bl –
-
B/Br)

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.
YES Go to Step 2. (When indicating C44/P0130:)
NO
W/G or W/Bl wire shorted to ground, or W/G and
W/Bl or B/Br wire open.
