6-42 FI SYSTEM/ CVT SYSTEM
“C44” HO2 SENSOR (HO2S) CIRCUIT MALFUNCTION (E-02, 19)
INSPECTION
• Remove the foot board. (
9-18)
DETECTED CONDITION
POSSIBLE CAUSE
During O2 feedback control, O2 sensor voltage is
higher or lower than the specification.
No signal is detected during engine operation, or no
electrical power is supplied from battery.
• HO2 sensor or its circuit open or short.
• Fuel system malfunction.
• ECM malfunction.
1 Turn the ignition switch OFF.
Check the HO2 sensor coupler for loose or poor contacts.
Insert the copper wires to the HO2 sensor lead wire coupler.
Warm up the engine enough.
Measure the HO2 sensor output voltage at the coupler
(between Black and Gray wires) when idling condition.
Also, measure the HO2 sensor output voltage while
holding the engine speed at 3 000 r/min.
No
Yes
Replace the HO2 sensor with
a new one.
