4-88 FI SYSTEM DIAGNOSIS
“C44” (P0130/P0135) HO2 SENSOR (HO2S) CIRCUIT MALFUNCTION

INSPECTION
Step 1 (When indicating C44/P0130:)
1) Turn the ignition switch OFF.
2) Remove the left under cowling. (8-5)
3) Check the HO2 sensor coupler  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  and ground.
6) Also, check the continuity between W/G wire  and B/Br wire
. 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 < 1.0 V)
In other than the above value, C44
(P0130) is indicated.
• HO2 sensor circuit open
C44
(P0135)
The heater can not operate so that
heater operation voltage is not supplied
to the oxygen heater circuit.
• HO2 sensor lead wire/coupler connection
• Battery voltage supply to the HO2 sensor.
