FI SYSTEM DIAGNOSIS 5-79
“C44” (P0156/P0161) or “C64” (P0130/P0135) HO2 SENSOR (HO2S)
CIRCUIT MALFUNCTION (FOR E-02, 19, 24)
INSPECTION
Step 1
(When indicating C44/P0156 for HO2 sensor #2)
(When indicating C64/P0130 for HO2 sensor #1)
1) Turn the ignition switch OFF.
2) Check the HO2 sensor for loose or poor contacts.
If OK, then check the HO2 sensor lead wire continuity.
3) Disconnect the HO2 sensor coupler.
4) Check the continuity between W/G (#1) or W/Bl (#2) wire
A
and ground.
5) Also, check the continuity between W/G (#1) or W/Bl (#2)
wire
A
and B/Br wire
B
. If the sound is not heard from the
tester, the circuit condition is OK.

DETECTED CONDITION
POSSIBLE CAUSE
C44/C64
(P0156/
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/C64
(P0161/
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.
