Item
Detail
Criterion
•
When oxygen sensor voltage is 1.4V or more
•
With air fuel ratio in closed loop control
-
When oxygen sensor voltage is 0.048 or less for 27 seconds
-
Except idling (more than certain rpm and negative pressure), when cooling
temperature is 15°C and in case of 0.348V < oxygen sensor voltage < 0.498V
for 27 seconds
Troubleshooting
1. Mixture adaptation control forbidden
•
Fix it as final value
2. Air fuel ratio in closed loop control
[NOTE]
By minimum to maximum value difference of oxygen sensor, injection fuel quan-
tity can be different up to 35%
Check lamp
Faulty sensor manage-
ment
SENSOR CHARACTERISTICS
•
OXYGEN SENSOR
Oxygen sensor/ Related circuit
1. Display oxygen sensor related circuit fault
2. Inspect bad connection of connector, faulty wiring
3. Check oxygen sensor for ground
-
Measure voltage between sensor body and engine ground :
If measured value is 20mv or less, inspect oxygen sensor parts.
If measured value is 20mv or more, clean sensor mounting part.
4. At sensor output function, inspect oxygen sensor
If fault code is detected, turned
ON
HI-SCAN
•
Possible to check fault
•
Possible to check oxygen sensor voltage
