Nissan Primera P11. Instruction — part 152
I
The voltage never exceeds 1.0V.
CAUTION:
I
Discard any heated oxygen sensor which has been
dropped from a height of more than 0.5 m (19.7 in) onto a
hard surface such as a concrete floor; use a new one.
I
Before installing new oxygen sensor, clean exhaust sys-
tem threads using Oxygen Sensor Thread Cleaner tool
and approved anti-seize lubricant.

ECM Terminals and Reference Value
NLEC0138
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM’s transistor. Use a ground other than ECM terminals, such as the ground.

DTC Confirmation Procedure
NLEC0140
NOTE:
If “DTC Confirmation Procedure” has been previously conducted,
always turn ignition switch “OFF” and wait at least 9 seconds
before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that bat-
tery voltage is between 10.5V and 16V at idle.
With CONSULT-II
1)
Turn ignition switch “ON” and select “DATA MONITOR” mode
with CONSULT-II.
2)
Start engine and run it for at least 5 seconds at idle speed.
3)
If 1st trip DTC is detected, go to “Diagnostic Procedure”, EC-
QG-169.
With GST
1)
Start engine and run it for at least 5 seconds at idle speed.
2)
Turn ignition switch “OFF” and wait at least 9 seconds.
3)
Start engine and run it for at least 5 seconds at idle speed.
4)
Select “MODE 3” with GST.
5)
If DTC is detected, go to “Diagnostic Procedure”, EC-QG-169.
I
When using GST, “DTC Confirmation Procedure” should
be performed twice as much as when using CONSULT-II
because GST cannot display MODE 7 (1st trip DTC) con-
cerning this diagnosis. Therefore, using CONSULT-II is
recommended.
