- Refer to Code No. P0130: Right bank oxygen sensor (front) circuit
.
- Refer to Code No. P0201: No. 1 injector system
.
- Refer to Code No. P0203: No. 3 injector system
.
- Refer to Code No. P0205: No. 5 injector system
.

- The engine-ECU <M/T> or engine-A/T-ECU <A/T>
effects air/fuel ratio feedback control in accordance with the signals
from the right bank oxygen
sensor (front).
- If the right bank oxygen sensor (front) has deteriorated, corrections
will be made
by the right bank oxygen sensor (rear).
- Code No. P0134 becomes stored in memory if a failure is detected in
the above air/fuel
ratio feedback control system.

|
Check Conditions
- 20 seconds or more have passed since the engine starting sequence was
completed.
- Engine coolant temperature is 76°C or more.
- Engine speed is higher than 1,200 r/min.
- Volumetric efficiency is 30 % or more.
- Throttle position sensor output voltage is 4 V or less.
- Except while fuel is being shut off.
- Monitoring time: 30 seconds.
|
|
Judgment Criterion
- Right bank oxygen sensor (front) output voltage does not get across
approximately
0.5 V within about 30 seconds.
|
|
- Failed right bank oxygen sensor (front)
- Exhaust leak
- Incorrect fuel pressure
- Failed engine-ECU <M/T> or engine-A/T-ECU
<A/T>
