“C44” (P0130/P0135) HO2 SENSOR (HO2S) CIRCUIT MALFUNCTION
(FOR E-02, 19, 24, 41)
INSPECTION
NOTE:
After repairing the trouble, clear the DTC using SDS tool.
Step 1 (When indicating C44/P0130:)
1) Turn the ignition switch OFF.
2) Remove the seat. (!DL650K4 7-4)
3) Check the HO2 sensor for loose or poor contacts.
If OK, then check the HO2 sensor lead wire continuity.
4)Disconnect the HO2 sensor coupler.
5) Check the continuity between W/G wire A and ground.
6) Also, check the continuity between W/G wire A and B/Br wire
B. If the sound is not heard from the tester, the circuit condi-
tion is OK.
# 09900-25008: Multi-circuit tester set
+ Tester knob indication: Continuity test (*)
DETECTED CONDITION POSSIBLE CAUSE
C44
(P0130)
HO2 sensor output voltage is not input
to ECM during engine operation and
running condition.
(Sensor voltage < 0.45 V)
• HO2 sensor circuit open or shorted to ground.
• Fuel system malfunction.
• ECM malfunction.
C44
(P0135)
The heater can not operate so that
heater operation voltage is not supply to
the oxygen heater circuit.
• Battery voltage supply to the HO2 sensor.
