14-86 VL800K5 (’05-MODEL)
“C44” (P0130/P0135) HO2 SENSOR (HO2S) CIRCUIT MALFUNCTION
(E-02, 19, 24)
INSPECTION
Step 1 (When indicating C44/P0130:)
1) Remove the right frame cover. ($7-2)
2) Turn the ignition switch OFF.
3) Check the HO2 sensor coupler for loose or poor contacts.

(P0130)
HO2 sensor output voltage is not input
to ECM during engine operation and
running condition.
(Sensor voltage 0.1 V)
• HO2 sensor circuit open or shorted to ground.
• HO2 sensor malfunction.
• ECM malfunction.
C44
