Maybe this?
The closed loop control has the one trip detection logic.
Malfunction is detected when the closed loop control function for
right bank does not operate even when vehicle is driving in the
specified condition, the closed loop control function for left bank
does not operate even when vehicle is driving in the specified
condition.
POSSIBLE CAUSES
The front heated oxygen sensor circuit is open or shorted.
Front heated oxygen sensor
Front heated oxygen sensor heater
ALSO
On Board Diagnosis Logic
To judge the malfunction of front heated oxygen sensor, this diagnosis
measures response time of front heated oxygen sensor signal.
The time is compensated by engine operating (speed and
load), fuel feedback control constant, and front heated oxygen sensor
temperature index. Judgment is based on whether the compensated
time (front heated oxygen sensor cycling time index) is inordinately
long or not.
Malfunction is detected when the response of the voltage signal
from the sensor takes more than the specified time.
POSSIBLE CAUSE
Harness or connectors (The sensor circuit is open or shorted.)
Front heated oxygen sensor
Front heated oxygen sensor heater
Fuel pressure
Injectors
Intake air leaks
Exhaust gas leaks
PCV valve
Mass air flow sensor (Image is of an Xterra Sensor)
