Nissan Primera P11. Instruction — part 239
Without CONSULT-II
1)
Start engine and warm it up to normal operating temperature.
2)
Set voltmeter probes between ECM terminal 62 (Heated oxy-
gen sensor 1 (front) signal) and engine ground.
3)
Check the following with engine speed held at 2,000 rpm con-
stant under no load.
I
Malfunction indicator goes on more than five times within 10
seconds in Diagnostic Test Mode II (HEATED OXYGEN SEN-
SOR 1 (FRONT) MONITOR).
I
The maximum voltage is over 0.6V at least one time.
I
The minimum voltage is below 0.3V at least one time.
I
The voltage never exceeds 1.0V.
CAUTION:
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.

(FRONT) (LEAN SHIFT MONITORING)

Component Inspection (Cont’d)
EC-155
Component Description
NCEC0111
The heated oxygen sensor 1 (front) is placed into the exhaust
manifold. It detects the amount of oxygen in the exhaust gas com-
pared to the outside air. The heated oxygen sensor 1 (front) has a
closed-end tube made of ceramic zirconia. The zirconia generates
voltage from approximately 1V in richer conditions to 0V in leaner
conditions. The heated oxygen sensor 1 (front) signal is sent to the
ECM. The ECM adjusts the injection pulse duration to achieve the
ideal air-fuel ratio. The ideal air-fuel ratio occurs near the radical
change from 1V to 0V.

On Board Diagnosis Logic
NCEC0114
To judge the malfunction, the output from the heated oxygen sen-
sor 1 (front) is monitored to determine whether the “rich” output is
sufficiently high. The “lean” output is sufficiently low. When both the
outputs are shifting to the rich side, the malfunction will be
detected.
DTC No.

DTC Confirmation Procedure
NCEC0115
CAUTION:
Always drive vehicle at a safe speed.
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:
I
Always perform at a temperature above −10°C (14°F).
I
Before performing the following procedure, confirm that
battery voltage is more than 11V at idle.
With CONSULT-II
1)
Start engine and warm it up to normal operating temperature.
2)
Stop engine and wait at least 9 seconds.
3)
Turn ignition switch “ON” and select “HO2S1 (B1) P0132” of
“HO2S1” in “DTC WORK SUPPORT” mode with CONSULT-II.
4)
Touch “START”.
5)
Start engine and let it idle for at least 3.5 minutes.
NOTE:
Never raise engine speed above 3,200 rpm after this step. If
the engine speed limit is exceeded, return to step 5.
6)
When the following conditions are met, “TESTING” will be dis-
played on the CONSULT-II screen. Maintain the conditions
continuously until “TESTING” changes to “COMPLETED”. (It
will take approximately 20 seconds or more.)

Overall Function Check
NCEC0116
Use this procedure to check the overall function of the heated oxy-
gen sensor 1 (front) circuit. During this check, a 1st trip DTC might
not be confirmed.
Without CONSULT-II
1)
Start engine and warm it up to normal operating temperature.
2)
Set voltmeter probes between ECM terminal 62 (Heated oxy-
gen sensor 1 (front) signal) and engine ground.
3)
Check the following with engine speed held at 2,000 rpm con-
stant under no load.
I
The maximum voltage is below 0.8V at least one time.
I
The minimum voltage is below 0.35V at least one time.
4)
If NG, go to “Diagnostic Procedure”, EC-SR-159.
